[QGIS-Developer] Experimental Qt6 Flatpak build available for Linux/Python devs (for updating plugins)

[Ulisse Cavallini]

Hi Hannes,


this could be due to the fact that the flatpak .desktop file has the 
same "Name". You could solve this by copying both the .desktop files 
(flatpak and system-wide) in your user application directory, for 
example (local paths may vary):

/cp /usr/share/applications/org.qgis.qgis.desktop 
~/.local/share/applications//

/cp /var/lib/flatpak/exports/share/applications/org.qgis.qgis.desktop 
~/.local/share/applications//

and change the name of one of the two (Name attribute), for example 
setting "QGIS Desktop Flatpak Qt6"

Should be automatically picked up, otherwise you can run

/update-desktop-database ~/.local/share/applications/

I hope this helps!

Cheers,

Ulisse
