ubuntu / xubuntu podman install

# aptitude install curl
# $(. /etc/os-release) \
echo "deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/testing/xUbuntu_"${VERSION_ID}"/ /" \
> /etc/apt/sources.list.d/devel:kubic:libcontainers:testing.list
# curl -L https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/testing/xUbuntu_${VERSION_ID}/Release.key | sudo apt-key add -
# aptitude install podman

one nice feature of the ubuntu / xubuntu podman installer is that it sets up /etc/subuid and /etc/subgid for existing users automatically
