Title:
Environment overwrites XDG_DATA_DIRS
Status in flatpak package in Ubuntu:
Fix Released
Status in flatpak source package in Focal:
Fix Released
Bug description:
[Impact]
Flatpak gdm environment overwrites any custom configuration (eg in
~/.config/environment.d ) while using the Wayland session.
[Test Case]
Create a local environment configuration
$ mkdir -p ~/.config/environment.d
$ echo "XDG_DATA_DIRS=${XDG_DATA_DIRS}:/tmp" >>
~/.config/environment.d/test.conf
Reboot and ensure you use the Wayland session. Then check your
XDG_DATA_DIRS from systemctl, the issue occurs when /tmp is not set,
the issue is resolved if it is set.
$ systemctl --user show-environment |grep XDG_DATA_DIRS
[Regression Potential]
Low. This only affects users using the Wayland session with a custom
environment (which are both non-standard configuration).
[Original Description]
Package contains this file:
/usr/share/gdm/env.d/flatpak.env
With this single line content:
XDG_DATA_DIRS=$HOME/.local/share/flatpak/exports/share/:/var/lib/flatpak/exports/share/:/usr/local/share/:/usr/share/
This is setting the XDG_DATA_DIRS variable, irrespective of it's
preexisting value.
In my system I have snapd installed and I have a local configuration
for that variable under .config/environment.d/, which gets overwritten
and causes issues.
