[Bug]: Flathub doesn't update in Ubuntu Touch

[Azkali]

After following the wiki instruction correctly flathub just never updates appstream and appstream2 in Ubuntu Touch giving no meaningfull logs either.

You can find the logs from a flatpak update on a fresh install.

Using the ppa version instead of ubuntu's solved this. Closing.
