How to Install and Use Incus Container in Ubuntu 22.04 LTS
This simple tutorial shows how to install and use Incus container in Ubuntu 22.04 and Ubuntu 20.04 LTS.
Incus is a free open-source system container and virtual machine manager developed by Linux Containers community. It supports images for a large number of Linux distributions.
With it, you can manage your containers and VMs either with a simple command line tool, directly through the REST API or by using third-party tools and integrations.
Incus was started as community fork of Canonical’s LXD. Now, it’s led and maintained by much of the same people that once created LXD.
Step 1: Install Incus
Incus is available in Zabbly repository maintained by the software developer. So far, it supports Ubuntu 22.04, Ubuntu 20.04, Debian 12 and Debian 11.
To install it, first open terminal from system start menu or Gnome activities overview screen. Ubuntu users can simply press
Ctrl+Alt+T on keyboard.
1. First, run 2 commands one by one to make sure
/etc/apt/keyrings exist, then download & install the key file:
sudo mkdir -p /etc/apt/keyrings
wget -qO - https://pkgs.zabbly.com/key.asc | sudo tee /etc/apt/keyrings/zabbly.asc
For Debian, run
sudo apt install wget first if wget command not found.
2. Then, run command to create source file and edit it with nano text editor:
sudo nano /etc/apt/sources.list.d/zabbly-incus-stable.sources
When it opens in the command line text editor, paste following lines:
Enabled: yes Types: deb URIs: https://pkgs.zabbly.com/incus/stable Suites: jammy Components: main Architectures: amd64 Signed-By: /etc/apt/keyrings/zabbly.asc
NOTE: You may need to replace jammy (for 22.04) with focal for Ubuntu 20.04, or bookworm/bullseye for Debian 12/11. Also replace amd64 according to
dpkg --print-architecture command output.
3. After properly adding the Zabbly repository and its key file, run the command to refresh system package cache:
sudo apt update
It should output with line says something “Get:x https://pkgs.zabbly.com/incus/stable …”. Finally, you can install the incus container by running command:
sudo apt install incus
For choice, you may also install the
incus-ui-canonical package for the web UI support.
Step 2: setup incus
After installed the container, you may run command first to verify its version:
Then, run command below and answer the questions to configure the daemon:
sudo incus admin init
To allow running incus commands without sudo privilege, you can add current user into incus-admin group:
sudo gpasswd --add $USER incus-admin
newgrp incus-admin in any terminal to interacts with Incus.
Step 3: Create/Delete containers
To create a container, for example called
mycontainer using the Debian 12 image, run command:
incus launch images:debian/12 mycontainer
Then list instances:
In the case, I can run command to get into bash shell for the Debian 12 container.
incus exec mycontainer bash
To delete the container instance
mycontainer, use command:
incus delete mycontainer
-f to force deleting running instance, and/or add
-i to require user confirmation.
Incus has many other command options, including
copy and more. You may run
incus --help to list them, and run
incus <command> --help to get help for each command.
For example, run the command below to tell how to create instances from images:
incus create --help

Uninstall incus container
To uninstall the container installed from Zabbly repository, open terminal and run command:
sudo apt remove --autoremove incus
You may also remove the Zabbly repository by deleting the source and key files via command:
sudo rm /etc/apt/sources.list.d/zabbly-incus-stable.sources /etc/apt/keyrings/zabbly.asc
Finally, refresh your system package cache via
sudo apt update.
