Launcher doesn't start (flatpak)

[pezz]

Seeing this when trying to start the flatpak launcher:

% flatpak run --command=fs-uae-launcher net.fsuae.FS-UAE
<bunch of python output>
ModuleNotFoundError: No module named 'urllib3.packages.six.moves'

Not sure if any other info is needed?

Edit: forgot the version, latest stable 3.1.66 built 4 days ago or so.

I have the same issue on Linux Mint Mate. FS-UAE works as normal, but FS-UAE Launcher stopped working after I did flatpak updates. In the terminal it spits the same error message as @pezz wrote above.

I have similar issues on Ubuntu 24.10, see attached log file. Happened after the most recent flatpak update.

Downgrading tp the previous flatpak release solves the issue, like e.g.:
sudo flatpak update --commit=6f238c385fd1e3ee70025058d4f92ebef71f3060cf10f70aeb52917e8398a3b3 net.fsuae.FS-UAE

@pezz Thanks for the solution. Even if it's not perfect FS-UAE Launcher works again. Thanks to you I've learned how to downgrade Flatpaks to make some other apps work again if needed. 😃

Using Xubuntu 24.04.

I noticed yesterday that the launcher wouldn't run (not sure since when, haven't used it in a while). I have a bit more Python errors when trying to start it from a terminal, FWIW:
