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

Tue Jun 17 00:13:49 PDT 2025

Hi Ulisse,

yes, that was it, thank you!

For my case the solution is simply removing the desktop file of the 
Flatpak QGIS:

/sudo rm /var/lib/flatpak/exports/share/applications/org.qgis.qgis.desktop
sudo update-desktop-database/

Now my system QGIS is working as intended and I can use the Flatpak QGIS 
for testing via

/flatpak run org.qgis.qgis/

Cheers, Hannes
