Podman binaries for Linux Mint / Ubuntu are hosted by OpenSuse.org.
You need to add the repository to /etc/source.list.d. Common instructions for Ubuntu might not work, because VERSION_ID for Mint is not the same as for Ubuntu.
Instructions for Linux Mint 20.2 from Ubuntu 20.04 repository:
export VERSION_ID="20.04"
sudo sh -c "echo 'deb https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /' > /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list"
sudo wget -nv https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_${VERSION_ID}/Release.key -O- | apt-key add -
sudo apt update
sudo apt install -y podman
Example of running container for IoT development:
If you’d like to develop for ESP32 chip connected to /dev/ttyUSB0 using C++ or Rust language, just start the container:
podman run --device /dev/ttyUSB0 -it docker.io/espressif/idf-rust-examples
