How to install latest version of podman on debian/ubuntu

I like stability of debian. I use it as my host distro for almost every server I have. But debian repositories (stable) have a very old version of podman. The same goes for debian testing, there’s simply no podman 5>= avaliable. Debian backports don’t work either - there’s no backport of podman.

That left me with one other option - static build of podman.

Installation on amd64 host

Copied from https://github.com/mgoltzsche/podman-static?tab=readme-ov-file#binary-installation-on-a-host

Download the statically linked binaries of podman and its dependencies:

curl -fsSL -o podman-linux-amd64.tar.gz https://github.com/mgoltzsche/podman-static/releases/latest/download/podman-linux-amd64.tar.gz

Verify signature:

curl -fsSL -o podman-linux-amd64.tar.gz.asc https://github.com/mgoltzsche/podman-static/releases/latest/download/podman-linux-amd64.tar.gz.asc
gpg --keyserver hkps://keyserver.ubuntu.com --recv-keys 0CCF102C4F95D89E583FF1D4F8B5AF50344BB503
gpg --batch --verify podman-linux-amd64.tar.gz.asc podman-linux-amd64.tar.gz

Install binaries on the host:

tar -xzf podman-linux-amd64.tar.gz
sudo cp -r podman-linux-amd64/usr podman-linux-amd64/etc /

Install additional binaries:

apt install uidmap nsenter iptables slirp4netns

Add UID/GID mapping

Check /etc/subuid and /etc/subgid for mappings:

cat /etc/subuid
cat /etc/subgid

If theres nothing in here add mapping:

sudo sh -c "echo $(id -un):100000:200000 >> /etc/subuid"
sudo sh -c "echo $(id -gn):100000:200000 >> /etc/subgid"

Persist containers after logout

Enable linger:

loginctl enable-linger <USERNAME>

Enable podman socket

systemctl enable --now --user podman.socket

Enable automatic restart of services

systemctl enable podman-restart.service

Source: https://github.com/containers/podman/blob/main/contrib/systemd/system/podman-restart.service.in

Install podman compose

apt install pipx
pipx install podman-compose

Check if everything is working

$ podman run quay.io/podman/hello
