Ubuntu 22.04: Top Things to Do After Installation

Some recommendations of mine what you can do after installing Ubuntu 22.04 LTS “Jammy Jellyfish”.

 

1. Remove Snap

sudo snap remove snap-store core18 snapd
rm -rf ~/snap
sudo rm -rf /snap
sudo rm -rf /var/snap
sudo rm -rf /var/lib/snapd
sudo rm -rf /var/cache/snapd
sudo apt autoremove --purge snapd

Prevent repository packages from triggering the installation of snap

sudo gedit /etc/apt/preferences.d/nosnap.pref

    # this file forbids snapd from being installed by APT

    Package: snapd
    Pin: release a=*
    Pin-Priority: -10

 

2. Install Firefox

Add Mozilla repository.

sudo add-apt-repository ppa:mozillateam/ppa
sudo apt update

Blocks Firefox installation based on snap packages.

echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox

echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | 
sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox

# install firefox
sudo apt install firefox 

 

3. Rename Network interfaces

Edit the file “/etc/default/grub” and change the line:

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Update grub and reboot.

sudo update-grub
sudo reboot

 

4. Change Boot animation

Edit the file “/etc/default/grub” and change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="noplymouth"

sudo update-grub
sudo reboot

 

5. Install Gnome Shell Extension

Install Gnome Shell Extension.

sudo apt-get install chrome-gnome-shell

Open the this link in Firefox and install the Add-on.

Open the address: https://extensions.gnome.org and install the following extensions:

applications-menu
dash-to-panel
Clipboard Indicator
Status Area Horizontal Spacing 
Arc menu
