The Complete Installation Guide for Xubuntu 22.04

This is a guide for installing Xubuntu 22.04 – the hard way. The partitioning scheme is laid out as:

+-------------------------++-----------++-----------++---------------------------+

+-------------------------++-----------------------------------------------------+

Warnings

  1. You may need to change some options for your install.
  2. Test in a virtual machine before use. Real hardware will still be different.
  3. If grub gets installed on the USB installation device, simply reboot with the installation USB, log in, and run sudo dpkg-reconfigure grub-pc. This will show a text interface where you can choose the installation disk(s).

Install Xubuntu 22.04 with dm-crypt LUKS encryption for all partitions

  1. Download Xubuntu 22.04 at https://xubuntu.org/download.

  2. Create a bootable USB. I suggest using https://github.com/jsamr/bootiso.

  3. Make sure you are using UEFI on the computer.

  4. Reboot computer from USB.

  5. Installer boot menu

    1. Try Xubuntu without installing

  6. Follow directions from https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019 for full partition encryption.

    1. Open the terminal

      #----------------------------------------------------------------------
# Identify installation device
#----------------------------------------------------------------------
# Switch to root user.
sudo -i

# Determine the target drive location.
lsblk

# Save shortcut reference to drive location (non-NVME drive).
#export DEV="/dev/sda"

# Save shortcut reference to drive location (NVME drive).
export DEV="/dev/nvme0n1"

# Shortcut reference to encrypted device mapper without leading `/dev/`.
export DM="${DEV##*/}"

# NVME devices need a 'p' before partition number. i.e. "nvme0n1p1".
export DEVP="${DEV}$( if [[ "$DEV" =~ "nvme" ]]; then echo "p"; fi )"
export DM="${DM}$( if [[ "$DM" =~ "nvme" ]]; then echo "p"; fi )"

#----------------------------------------------------------------------
# Partitioning
#----------------------------------------------------------------------
# Check for pre-existing partitions.
sgdisk --print $DEV

# ***If safe to delete all partitions***
#sgdisk --zap-all $DEV

# If anything goes wrong, check Gparted or `fdisk -l $DEV`.
sgdisk --new=1:0:+768M $DEV
sgdisk --new=2:0:+2M $DEV
sgdisk --new=3:0:+128M $DEV
sgdisk --new=5:0:0 $DEV
sgdisk --typecode=1:8301 --typecode=2:ef02 --typecode=3:ef00 --typecode=5:8301 $DEV
sgdisk --change-name=1:/boot --change-name=2:GRUB --change-name=3:EFI-SP --change-name=5:rootfs $DEV
sgdisk --hybrid 1:2:3 $DEV

#----------------------------------------------------------------------
# LUKS Encryption
#----------------------------------------------------------------------
# Make sure to use luks version 1 on /boot/ since GRUB requires it.
cryptsetup luksFormat --type=luks1 ${DEVP}1

# Set up LUKS on the system partition.
cryptsetup luksFormat ${DEVP}5

#  Open the encrypted devices.
cryptsetup open ${DEVP}1 LUKS_BOOT
cryptsetup open ${DEVP}5 ${DM}5_crypt
ls /dev/mapper/

#----------------------------------------------------------------------
# Format file systems
#----------------------------------------------------------------------
mkfs.ext4 -L boot /dev/mapper/LUKS_BOOT
mkfs.vfat -F 16 -n EFI-SP ${DEVP}3

#----------------------------------------------------------------------
# LVM Logical Volume Manager
#----------------------------------------------------------------------
# Naming scheme for different releases of ubuntu
flavour="$( sed -n 's/.*cdrom:\[\([^ ]*\).*/\1/p' /etc/apt/sources.list )"
release="$( lsb_release -sr | tr -d . )"
if [ ${release} -ge 2204 ]; then VGNAME="vg${flavour,,}"; else VGNAME="${flavour}--vg"; fi 
export VGNAME

# Create Volumes
pvcreate /dev/mapper/${DM}5_crypt
vgcreate "${VGNAME}" /dev/mapper/${DM}5_crypt
# If you want a swap partition/volume
#lvcreate -L 1G -n swap_1 "${VGNAME}"
lvcreate -l 80%FREE -n root "${VGNAME}"

    2. Keep terminal open, but switch back to proceeding with installation.

  7. Installer main menu

    1. Keyboard layout

      1. English (US)

    2. Updates and other software

      1. Download updates while installing Xubuntu
      2. Install third-party software

    3. Installation type

      1. Something else
        1. Select the root file-system device for formatting (/dev/mapper/vgxubuntu-root), press the Change button, choose Use As Ext4 and Mount point /.
        2. If you created a swap volume: Select the swap device (/dev/mapper/vgxubuntu-swap_1), press the Change button, choose Use as swap area.
        3. Select the Boot file-system device for formatting (/dev/mapper/LUKS_BOOT), press the Change button. choose Use as Ext4… and Mount point /boot
        4. Select the boot-loader device (/dev/nvme0n1p1 for example). Boot-loader device should always be a raw disk not a partition or device-mapper node.
        5. Press the Install Now button to write the changes to the disk and press the Continue button.

    4. Where are you

    5. Who are you

      • After finishing this step, immediately perform next step. The next step needs to be run before installation is finished in the background?

    6. Open the terminal

      1. while [ ! -d /target/etc/default/grub.d ]; do sleep 1; done; echo "GRUB_ENABLE_CRYPTODISK=y" > /target/etc/default/grub.d/local.cfg
        • Check file for successful addition of text.

    7. After successful installation, choose continue testing.

    8. Open the terminal

      #-----------------------------------------------------------------------
# Change-root environment to work in the newly installed OS
#-----------------------------------------------------------------------
mount /dev/mapper/${VGNAME}-root /target
for n in proc sys dev etc/resolv.conf; do mount --rbind /$n /target/$n; done
chroot /target
mount -a

#-----------------------------------------------------------------------
# Configure cryptsetup-initramfs and key file
#-----------------------------------------------------------------------
apt install -y cryptsetup-initramfs

# Note that since we chroot'd to `/target` the following changes will be
# made in the files at the /target path.
echo "KEYFILE_PATTERN=/etc/luks/*.keyfile" >> /etc/cryptsetup-initramfs/conf-hook
echo "UMASK=0077" >> /etc/initramfs-tools/initramfs.conf

# Create a randomised key-file of 4096 bits (512 bytes), secure it, and add it to the LUKS volumes
mkdir /etc/luks
dd if=/dev/urandom of=/etc/luks/boot_os.keyfile bs=512 count=1

chmod u=rx,go-rwx /etc/luks
chmod u=r,go-rwx /etc/luks/boot_os.keyfile

cryptsetup luksAddKey ${DEVP}1 /etc/luks/boot_os.keyfile
cryptsetup luksAddKey ${DEVP}5 /etc/luks/boot_os.keyfile

# Add the keys to the crypttab
echo "LUKS_BOOT UUID=$(blkid -s UUID -o value ${DEVP}1) /etc/luks/boot_os.keyfile luks,discard" >> /etc/crypttab
echo "${DM}5_crypt UUID=$(blkid -s UUID -o value ${DEVP}5) /etc/luks/boot_os.keyfile luks,discard" >> /etc/crypttab

# Update the initialramfs files to add the cryptsetup unlocking scripts and the key-file
update-initramfs -u -k all

  8. Reboot the computer and remove installation media. You should be asked for the password at GRUB.

Post install options

  1. Set audio/sound/volume level using keyboard shortcuts.

    In Settings -> Keyboard -> Application Shortcuts, click add, then insert

    amixer -D pulse set Master 5%+
amixer -D pulse set Master 5%-
amixer -D pulse set Master toggle

  2. Set window tile keybinds.

    1. Open terminal and run
      1. xfce4-settings-manager
    2. Go to window manager
      1. Open the Keyboard tab
        1. Set the “Tile window to the left” (and right)

  3. Set backbutton in firefox to backsapce.

    1. Type about:config in the address bar
    2. Look for browser.backspace_action in the list
    3. Change the Value to 0.

  4. Change desktop lock keybind.

    1. Go to settings editor
    2. xfce4-keyboard-shortcuts
    3. new commands custom property
      1. property: /commands/custom/<super>l
      2. type: string
      3. value: xflock4

  5. Fix laptop screen brightness steps

    In Settings -> Power Manager -> General, there is an option for “Brightness step count”. Increase this to a value such as 20.

    Otherwise, tools such as acpilight, light, and xbacklight may be of help. If you sudo make install acpilight, then you will need to run sudo usermod -a -G video USERNAME so that sudo is not required to execute xbacklight. You can then bind the command to a key combo under Settings -> Keyboard -> Application Shortcuts.

  6. Enable the firewall.

    # https://help.ubuntu.com/community/UFW
# https://www.linode.com/docs/security/firewalls/configure-firewall-with-ufw/
sudo ufw enable
sudo ufw default deny outgoing
sudo ufw default deny incoming

sudo ufw allow out to any port 80
sudo ufw allow out to any port 443
sudo ufw allow out to any port 53

# additional ports to allow out
# https://www.cups.org/doc/firewalls.html
# brother printer: 54925, 54926, 137, 161

sudo ufw reload
sudo ufw status verbose

# If anything goes wrong, you can reset ufw
#sudo ufw --force reset

  7. Edit the hosts file

    1. Grab the hosts file from https://github.com/StevenBlack/hosts
    2. paste into /etc/hosts

  8. Update the Linux kernel.

    1. If you want a specific kernel
      1. Download the following from http://kernel.ubuntu.com/~kernel-ppa/mainline/
        1. linux-headers-5.*-generic_*_amd64.deb
        2. linux-headers-5.*_all.deb
        3. linux-image-unsigned-5.*-generic_*_amd64.deb
        4. linux-modules-5.*-generic_*_amd64.deb
      2. Open terminal in download location and run
        1. sudo dpkg -i linux-headers*.deb
        2. sudo dpkg -i linux-modules*.deb
        3. sudo dpkg -i linux-image*.deb
        4. sudo update-grub
      3. Restart computer
      4. Check kernel being used with
        1. uname -a
      5. Remove old kernels if /boot gets full

  9. Check disk io/r/w transactions

    1. sudo iotop -oPa

  10. If there is a separate partition or disk that needs to be mounted and unencrypted at boot. Reference http://ubuntuforums.org/showthread.php?t=837416.

    1. Check UUID of partitioning
      1. sudo blkid
    2. Check block size of / (root) partition for nice key size (likely 4096)
      1. sudo blockdev --getbsz /dev/mapper/system-root
    3. Create random keyfile in /root
      1. sudo dd if=/dev/urandom of=/root/keyfile bs=4096 count=1
        • the bs= value should be the block size we just found
    4. Make keyfile read only to root
      1. sudo chmod 0400 /root/keyfile
    5. Add keyfile to LUKS partition of /dev/sdX#_crypt
      1. sudo cryptsetup luksAddKey /dev/sdX#_crypt /root/keyfile
        • Enter existing password for /dev/sdX#_crypt
    6. Create mapper
      1. sudo mousepad /etc/crypttab
      2. add ‘/root/keyfile’ to replace ’none’ for /dev/sdX#_crypt
        • example: sdX#_crypt UUID=XXX /root/keyfile luks
    7. Mount the drive (if needed)
      1. sudo mousepad /etc/fstab
        • example: /dev/mapper/sdX#_crypt /<mount point> btrfs relatime 0 2
    8. Update settings in initramfs images
      1. sudo update-initramfs -u -k all

  11. TRIM for SSDs.

    1. Reference http://blog.neutrino.es/2013/howto-properly-activate-trim-for-your-ssd-on-linux-fstrim-lvm-and-dmcrypt/.
    2. Enable Trim on dm-crypt
      1. Open /etc/crypttab
        1. sudo mousepad /etc/crypttab
        2. If needed, add ‘discard’ to the options for sdX#_crypt.
    3. Make sure LVM has ‘issue_discards=1’ in
      1. sudo mousepad /etc/lvm/lvm.conf
    4. Check encrypted drive with
      1. sudo dmsetup table /dev/mapper/sdX#_crypt
      2. make sure it has ‘1 allow_discards’
    5. Remove or check “discard” is not used in the fstab
      1. sudo mousepad /etc/fstab
    6. Run TRIM manually or check for errors
      1. sudo fstrim -v /home
    7. If any changes were made, run
      1. sudo update-initramfs -c -k all

  12. If installing in Virtualbox, install additions by

    1. sudo apt install virtualbox-guest-utils virtualbox-guest-dkms dkms
    2. To share a folder, make a permanent machine folder then run
      1. sudo usermod -a -G vboxsf username
    3. To share a USB port
      1. sudo usermod -a -G vboxusers username

  13. If needed, install Intel wireless driver.

    1. Download driver from http://intellinuxwireless.org/?n=Downloads
    2. Navigate to download folder
      1. tar xvzf iwlwifi-XXX.tgz
      2. cd iwlwifi-XXX/
      3. sudo cp iwlwifi-XXX.ucode /lib/firmware

  14. Check partition sizes.

    1. df -h

  15. Modify or redirect home folder names.

    1. change in /home/username/.config/user-dir.dirs

  16. Change ownership of extra storage drives or partitions.

    1. sudo chown -R username /partition

  17. Format a USB drive.

    1. df
    2. umount /dev/sdc1
    3. mkfs.vfat /dev/sdc1

  18. Create a dm-crypt LUKS encrypted external drive.

    Reference https://gitlab.com/cryptsetup/cryptsetup/wikis/FrequentlyAskedQuestions.

    1. Find the external drive (assume the filesystem is /dev/sdb1 and it’s mount location /media/USERNAME/*)

      df

    2. Unmount it

      umount /media/USERNAME/*

    3. Quickly wipe old filesystems. wipefs clears the first superblock.

      sudo wipefs -a /dev/sdb1

    4. Create the LUKS container (follow on-screen intructions)

      sudo cryptsetup luksFormat /dev/sdb1

    5. Check the passphrase iteration count. The key slot default is 1 second of PBKDF2 hashing. The volume key default (MK iterations) is 0.125 seconds. You can set the key slot with cryptsetup luksFormat -i 15000 <target device>

      sudo cryptsetup luksDump /dev/sdb1

    6. Map the container to /dev/mapper/backup1

      sudo cryptsetup luksOpen /dev/sdb1 backup1

    7. Create a filesystem in the mapped container

      sudo mkfs.btrfs --label backup1 /dev/mapper/backup1

    8. Mount the filesystem (right after creation; using lzo compression)

      mount -o compress=lzo /dev/mapper/backup1 /mnt

    9. Mount the filesystem (day to day use as a portable external drive; using lzo compression). You can either create an fstab entry or mount using the command line.

      • Using an fstab entry

        # Get the UUID of the mounted and unlocked /dev/mapper/ filesystem
sudo blkid

        Add the following entry to /etc/fstab

        UUID=YOUR-UUID /media/backup1 btrfs noauto,defaults,noatime,compress=lzo 0 0

        Now it will automatically mount at /media/backup1. The noauto option is used in the fstab entry to prevent automatically mounting the drive at boot time. If you leave this option off, then your computer will fail to boot and you will need to edit the fstab in recovery mode. The nofail option can be used for drives that are usually going to be mounted at boot time.

        Change ownership of the new mount point so you can perform cut/copy/paste, etc.

        sudo chown -R USERNAME /media/backup1

      • Using the terminal

        # The OS will automatically mount the drive and ask for passphrase to unlock. Then...
df
sudo umount /media/USERNAME/*
sudo mount -o compress=lzo /dev/dm-4 /media/backup1
sudo chown -R USERNAME /media/backup1

  19. Stop system error pop ups.

    Sometimes a system error will be reported and cause a warning pop up over multiple restarts. You can remove this by either

    1. sudo rm /var/crash/*
    2. gksu nano /etc/default/apport and set enabled=0

  20. Randomize MAC address.

    This is based on https://fedoramagazine.org/randomize-mac-address-nm/. To randomize wifi connections, create the file /etc/NetworkManager/conf.d/00-macrandomize.conf and add the following:

    # can use 'random' or 'stable' below
[device]
wifi.scan-rand-mac-address=yes

[connection]
wifi.cloned-mac-address=stable
ethernet.cloned-mac-address=stable
connection.stable-id=${CONNECTION}/${BOOT}

    Then restart networkmanager with systemctl restart NetworkManager.

  21. Change owner of entire directory.

    sudo chown -R <username> *

  22. Let apt fix dependency issues automatically.

    sudo apt --fix-broken install

  23. GPG bug fix when adding keys behind a proxy: use the option http-proxy=

    sudo apt-key adv --keyserver keyserver.ubuntu.com --keyserver-options http-proxy=http://PROXYADDRESS --recv-keys GPGKEY

  24. Fix bluetooth audio stuttering.

    Open a terminal and run

    sudo mousepad /etc/bluetooth/audio.conf

    Then add the following text to the new file:

    [General]
Enable=Source,Sink,Media,Socket

    Finally, restart the bluetooth service

    sudo service bluetooth restart

  25. Fix bluetooth audio not working.

    Open a terminal and run

    lsmod | grep btusb
sudo rmmod btusb
lsmod | grep btusb
sudo modprobe btusb
lsmod | grep btusb
bluetoothctl
scan on

  26. Fix QT scaling for hidpi displays.

    Open ~/.profile and append

    export QT_SCALE_FACTOR=2

Manual packages

  1. Install rig

    rig automatically installs pak in the user library. pak is nice because it installs R packages as binaries instead of from source. However, OS package dependencies are installed in the background using sudo, and we need to allow a graphical interface to insert the password. So we solve that by running:

    sudo apt install ssh-askpass ssh-askpass-gnome

    then append to the file /etc/sudo.conf

    # append to /etc/sudo.conf
Path askpass /usr/bin/ssh-askpass

    Each OS package dependency is executed in a seperate process, which means each process requires its own password authentication. We need to add a global sudo time limit for all processes.

    sudo visudo -f /etc/sudoers.d/timestamp_type

    then paste in the following text:

    # specify the timeout type (usual default=tty)
Defaults:USERNAME timestamp_type=global

# specify the timeout interval (usual default=15)
Defaults:USERNAME timestamp_timeout=2

    Finally, we install rig:

    curl -Ls https://github.com/r-lib/rig/releases/download/latest/rig-linux-latest.tar.gz | sudo tar xz -C /usr/local

    and then install R

    rig add release

    and can use pak::pkg_install() without any issues.

  2. Install GnuCash

    flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

flatpak install flathub org.gnucash.GnuCash

# uninstall
#flatpak uninstall org.gnucash.GnuCash

# Update stock quotes
# https://wiki.gnucash.org/wiki/Flatpak
flatpak run --command=gnucash-cli org.gnucash.GnuCash --quotes get /path/to/file.gnucash

  3. Install texlive 2022

    Reference http://tex.stackexchange.com/a/95373.

    1. Run

      sudo apt install wget perl-tk

wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
tar -zxvf install-tl-unx.tar.gz
cd install-tl*
sudo ./install-tl --gui
      • Choose the small scheme (just download fonts and packages as you need them)
      • Choose Recommended fonts, Mathematics packages, and LuaTeX packages
      • Make sure to “create symlinks in system directories”

    2. Run following from the shell. It will add the lines to /etc/environment. Or add to ~/.profile manually.

      export MANPATH="$MANPATH:/usr/local/texlive/2022/texmf-dist/doc/man"
export INFOPATH="$INFOPATH:/usr/local/texlive/2022/texmf-dist/doc/info"
export PATH=/usr/local/texlive/2022/bin/x86_64-linux:$PATH

    3. Make apt see the local install by:

      sudo apt install equivs --no-install-recommends
sudo apt install freeglut3
mkdir /tmp/tl-equivs
cd /tmp/tl-equivs
equivs-control texlive-local
# copy this http://www.tug.org/texlive/files/debian-equivs-2022-ex.txt to
mousepad texlive-local
equivs-build texlive-local
sudo dpkg -i texlive-local_2022-1_all.deb
