Description Thiago Sueto 2024-05-20 16:00:35 UTC 
SUMMARY
I'm on SteamOS (Steam Deck running Plasma 5).

To save space on my Steam Deck, I have an extra installation for flatpaks that is stored on my SD card, as per flatpak-installation: https://man.archlinux.org/man/extra/flatpak/flatpak-installation.5.en

Once I moved all my flatpaks to my SD card, the flatpak KCM stopped being able to detect my flatpaks.

STEPS TO REPRODUCE
1. Create a file /etc/flatpak/installations.d/extra.conf
2. Add a conf file pointing to some non-standard installation
3. sudo flatpak install --installation=<installname> <packagename>
4. Check the flatpak KCM app list

EXAMPLE CONFIG
[Installation "sdcard"]
Path=/run/media/mmcblk0p1/flatpak/
DisplayName=Extra Installation
StorageType=sdcard

OBSERVED RESULT
The flatpak installed to the custom installation path does not show up in the KCM.

EXPECTED RESULT
The flatpak installed to the custom installation path should show up in the KCM.

Is this basically a duplicate of https://bugs.kde.org/show_bug.cgi?id=485189 ? Or maybe that one is for supporting GUI to manually add them, and this one is "simply" to work with what's already registered with Flatpak…

Yeah, the other bug report is for the lack of a GUI to set a custom installation. This one is about the flatpak KCM being unable to detect any flatpaks from a custom installation that was already set.
