Packages for Ubuntu 20.04 (Focal), Ubuntu 18.04 (Bionic), and Ubuntu 16 (Xenial) are available in the SaltStack repository.
Instructions are at https://repo.saltstack.com/#ubuntu.
Archived builds from unsupported branches:
If looking to use archives, the same directions from the Ubuntu install
directions can be used by replacing
the URL paths with the appropriate archive location. The
repository configuration endpoint also needs to be adjusted to point to the
archives. Here is an example
# Salt repo configurations are found in the /etc/apt/sources.list.d/saltstack.list directory sed -i 's/repo.saltstack.com/archive.repo.saltstack.com/g' /etc/apt/sources.list.d/saltstack.list
Install the Salt master, minion or other packages from the repository with the apt-get command. These examples each install one of Salt components, but more than one package name may be given at a time:
apt-get install salt-api
apt-get install salt-cloud
apt-get install salt-master
apt-get install salt-minion
apt-get install salt-ssh
apt-get install salt-syndic
