Hi Gael, this is not a QGIS problem, but one of your installed plugins is causing the issue. The first line mentions it already > Couldn't load plugin 'crayfish'
I don't know the plugin, but you could try to delete / uninstall it and reinstall it again. If you go in a terminal to /home/kermarrec/.local/share/QGIS/QGIS3/profiles/default/python/plugins and delete the 'crayfish' folder, QGIS should start without the error. Further down the line the vrtbuilder plugin is mentioned as well, you might want to delete and reinstall it as well, just to be sure if the crayfish plugin is a dependency of the vrtbuilder plugin.

I have no idea what I should do to make it works. Maybe somebody had the same problem, I would be grateful to get some support as I would like to work with QGis. It looks as though you might be trying to work with the ubuntugis PPA. If that's so, maybe you should consider trying the suggested methodology on the QGIS site here: https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu If you just want to correct the unsatisfied dependencies, it's probably worth trying your command again with the "-f" option: apt install -f qgis qgis-plugin-grass In any event, I suggest you read this useful mini-tutorial on fixing unsatisfied dependencies. https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler. -- -------********--------- Dr. Gael Kermarrec Institute for meteorology and climatology Leibniz Universität Hannover Herrenhäuser Str. 2 D-30419 Hannover Tel: +49 511 762 2679 Email: kermar...@meteo.uni-hannover.de<mailto:kermar...@meteo.uni-hannover.de> Web: www.meteo.uni-hannover.de<http://www.meteo.uni-hannover.de>
