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.</span></div>

<br>
I am trying to install Qgis from Ubuntu 20.04 but everytime I make sudo<br>
apt install qgis qgis-plugin-grass I become the following:<br>
<br>
<br>
The following packages contain unsatisfied dependencies:<br>
qgis: Depends on python3-qgis (= 1:3.22.16+32focal) but<br>
1:3.26.3+32focal-ubuntugis needs to be installed<br>
Depends on qgis-providers (= 1:3.22.16+32focal) but<br>
1:3.26.3+32focal-ubuntugis needs to be installed<br>
Depends on qgis-common (= 1:3.22.16+32focal) but<br>
1:3.26.3+32focal-ubuntugis needs to be installed<br>
qgis-plugin-grass: Depends on qgis-plugin-grass-common (=<br>
1:3.22.16+32focal) but 1:3.26.3+32focal-ubuntugis needs to be installed<br>
Depends on grass782<br>
E: Unable to correct problems, defective packages are in "keep in the<br>
current state" mode.<br>
<br>
I have no idea what I should do to make it works. Maybe somebody had the<br>
same problem, I would be grateful to get some support as I would like to<br>
work with QGis.<br>

<div style="direction: ltr;">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:</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;"><a href="https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu" id="OWAc73b392a-51c0-f099-7bad-b75b4c699310" class="x_moz-txt-link-freetext OWAAutoLink" data-auth="NotApplicable" data-loopstyle="linkonly">https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu</a><br>
<br>
If you just want to correct the unsatisfied dependencies, it's probably worth trying your command again with the "-f" option:</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">apt install -f qgis qgis-plugin-grass</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">In any event, I suggest you read this useful mini-tutorial on fixing unsatisfied dependencies.</div>
