You won’t find Podman in the default
repositories configured on Linux Mint. To install it using
apt
you will need to configure a third party repository
that provides a Debian package for it. The Kubic
project provides recent packages for Podman (in addition to other
useful tools for working with containers). It’s worth noting that the
project does not provide a specific Linux Mint build but, being a
Debian-based distribution, the Ubuntu build seems to work just fine.
I use the Ubuntu 20.04 source in this example. You could also use the other Debian-based build targets listed though your mileage may vary.
SOURCE="xUbuntu_20.04"
# Adds the Kubic Debian repository to the systems apt sources.
echo "deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/${SOURCE}/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list
# Adds the repository encryption key for verifying package signatures.
curl -L "https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/${SOURCE}/Release.key" | sudo apt-key add -
sudo apt update
sudo apt install podman
Now you can verify your installation.
podman run hello-world
