Stops startup with"An error occured while setting up locale."

CharlemagneLasse commented 2 months ago

The appimage is working perfectly fine but the flatpak application is refusing to start up

flatpak run com.prusa3d.PrusaSlicer                   
--------------------------------------------------------------------------

Message: 13:15:30: WARN: Executing prusa-slicer with locale workaround de_DE.UTF-8
An error occured while setting up locale.
You may need to reconfigure the missing locales, likely by running the "locale-gen" and "dpkg-reconfigure locales" commands.
PrusaSlicer will now terminate.

It seems like the locales were not installed in the flatpak container:

$ flatpak run --command=bash com.prusa3d.PrusaSlicer

So it seems like the workaround from #27 cannot work because it tries to use LANG=de_DE.UTF-8 as a workaround but doesn't have this locale installed at all.

Hi @CharlemagneLasse, can you post the output of flatpak config --list?

CharlemagneLasse commented 2 months ago

$ flatpak config --list
languages: *unset* (default: en)
extra-languages: *unset*

No idea what this is - it doesn't seem to be documented here: https://flathub.org/apps/com.prusa3d.PrusaSlicer or https://flathub.org/setup/Debian

eliadevito commented 2 months ago

flatpak config allow you to configure flatpak apps locale, it is documented here: https://docs.flatpak.org/en/latest/flatpak-command-reference.html#flatpak-config

you can configure locale that want to use in your flatpak app with

flatpak config --set languages "LOCLAE_SEPARATED_BY_SEMICOLON"

and after install it with

flatpak update

for example if you want to install English and German languages you should do

flatpak config --set languages "en;de"
flatpak update
