Terminal cheat sheet
Here's a small reference for working with postmarketOS/Alpine Linux.
The package manager in postmarketOS is called
apk, the Alpine Package Keeper. The list of packages can be found on https://pkgs.alpinelinux.org/packages and https://pkgs.postmarketos.org/packages as both repositories are added to postmarketOS installations.
Installing a package
$ apk add vim
Uninstalling a package
$ apk del vim
Upgrading the system. The
-a option allows downgrading packages to what's available in the repository. This is sometimes needed when packages are moved from a git version to a stable release.
$ apk upgrade -a
The repositories are stored in
/etc/apk/repositories as one repository url per line. There's also
/etc/apk/world which is a list of packages that are explicitly installed. It's possible to add/remove packages from this list and then running
apk fix to apply those changes.
The service manager in postmarketOS is openrc. The basic service management is done with the familiar
$ service networkmanager status $ service networkmanager start $ service networkmanager stop $ service networkmanager restart
To enable or disable services on boot you use the
$ rc-update ... output ... Start NetworkManager on boot (in the default runlevel) $ rc-update add networkmanager default Stop NetworkManager starting on boot $ rc-update del networkmanager default
