Flatpak is the new framework for desktop applications on Linux
|
|
|
|
Distributing applications on Linux is a pain: different distributions
|
|
in multiple versions, each with their own versions of libraries and
|
|
packaging formats. Flatpak is here to change all that. It allows the
|
|
same app to be installed on different Linux distributions, including
|
|
different versions. And it has been designed from the ground up with
|
|
security in mind, so that apps are isolated from each other and from
|
|
the host system.
|
|
|
|
You can find many apps already available on https://flathub.org/
|
|
Add flathub for system and your user's home folder with:
|
|
|
|
sudo flatpak remote-add --if-not-exists flathub \
|
|
https://dl.flathub.org/repo/flathub.flatpakrepo
|
|
flatpak --user remote-add --if-not-exists flathub \
|
|
https://dl.flathub.org/repo/flathub.flatpakrepo
|
|
|
|
Apps that require pulse audio (like steam, skype, etc) need
|
|
PULSE_SERVER environment variable to be set. This is not set for most
|
|
shells in slackware by default. One way I found to set this is:
|
|
|
|
export `xprop -root -notype PULSE_SERVER | tr -d ' '`
|
|
|
|
A cleaner approach is to run `start-pulseaudio-x11` and then
|
|
`pax11publish -i` so the correct PULSE_SERVER variable is
|
|
exported. Adding these two commands to your ~/.xsession would be
|
|
useful.
|
|
|
|
Some of the examples from http://flatpak.org/#users are relying
|
|
on polkit helpers, that expect a user in the 'wheel' group to have
|
|
privileges for, but default polkit admin rule for slackware is just
|
|
the root user. So, if you run a command like:
|
|
|
|
flatpak remote-add --from gnome https://sdk.gnome.org/gnome.flatpakrepo
|
|
flatpak remote-add --from gnome-apps \
|
|
https://sdk.gnome.org/gnome-apps.flatpakrepo
|
|
|
|
as a limited user, you will get a polkit prompt for root's
|
|
password. This is because the default location for establishing these
|
|
repos is in `/var/lib/flatpak` and requires admin privileges.
|
|
|
|
You can optionally add the flag `--user` to flatpak commands, and it
|
|
will instead manage the repos in `~/.local/share/flatpak`.
|
|
|
|
There are examples of flatpak runtimes and applications on their wiki:
|
|
https://github.com/flatpak/flatpak/wiki/Examples
|
|
|
|
They too have desktop launchers search by desktops like KDE and XFCE,
|
|
it will require a logout, as /etc/profile.d/flatpak.sh will need to
|
|
be sourced.
