APT (Advanced Package Tool)¶

Basic Usage¶

Update package list: sudo apt update
Upgrade all packages: sudo apt upgrade
Install software: sudo apt install <package-name>
Uninstall software: sudo apt remove <package-name>
Search for software: apt search <keyword>
Display package information: apt show <package-name>
Display Version table, installed, next version: apt policy <package-name>

sudo rm /etc/apt/sources.list.d/<package>

Principles¶

APT is an advanced package management tool that uses dpkg as its backend. APT can:

Resolve dependencies
Fetch packages from configured sources
Perform complex package management operations

PPA Configuration¶

PPA (Personal Package Archive) allows developers and users to create their own software repositories.

Add PPA: sudo add-apt-repository ppa:<repository-name>
Remove PPA: sudo add-apt-repository --remove ppa:<repository-name>

PPA source files are located in the /etc/apt/sources.list.d/ directory.

Add Personal Repo¶

https://wiki.debian.org/DebianRepository/Format?action=show&redirect=RepositoryFormat Here's how to configure GPG signing in CI:

https://wiki.debian.org/DebianRepository/Setup

Generate GPG key (locally):

gpg --full-generate-key
gpg --list-secret-keys --keyid-format LONG
gpg --armor --export-secret-key YOUR_KEY_ID > private.key
gpg --armor --export YOUR_KEY_ID > public.key

Add keys as GitHub Secrets: - Go to repo Settings -> Secrets and variables -> Actions -> Repository secrets - Add two secrets - GPG_PRIVATE_KEY: private key content - GPG_PASSPHRASE: key passphrase

Flatpak ¶

Flatpak is a system for building and distributing desktop applications.

Install the Software Flatpak Plugin¶

The Flatpak plugin for the Software app makes it possible to install apps without needing the command line. To install, run:

sudo apt install gnome-software-plugin-flatpak

Note

the Software app is distributed as a Snap since Ubuntu 20.04 and does not support graphical installation of Flatpak apps. Installing the Flatpak plugin will also install a deb version of Software and result in two Software apps being installed at the same time.

Add the Flathub Repository¶

Flathub is the best place to get Flatpak apps. To enable it, run:

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

Restart¶

To complete setup, restart your system. Now all you have to do is install some apps!
