opened on Jan 17, 2026

After update to version 1.0.0, Nyarch Asssitant crashes a few seconds after opening due to a fatal error produced when installing the python build dependencies of the app.

This is the system I use attached as hyfetch picture:

    Try removing pip path

    ~/.var/app/moe.nyarchlinux.assistant/config/pip

    It looks like the issue is not mojimoji though.

    Hm you have kokoro as TTS, I guess it's better if you delete the whole settings entirely. I will check issues with kokoro for 1.2.1
    Delete ~/.var/app/moe.nyarchlinux.assistant

    yep, not optimally but they work
    on the previous versions the app only worked when launched from terminal

    The relevant part of the error is

    ** (nyarchassistant:2): ERROR **: 20:11:44.387: readPIDFromPeer: Unexpected short read from PID socket. (This usually means the auxiliary process crashed immediately. Investigate that instead!)

    Looking online looks like the reason is more flatpak rather than the application itself.
    Maybe the application now does some flatpak-spawn that your particular environment does not like or has some other problematic subprocess.
    Do you know if 1.1.0 works correctly?
