Andrea,

Thank you for testing the multibit AppImage. I suspected there would be problems with multibit. I will see what I can find today and will recreate it on the Fedora desktop where the AppImage did not work (instead of Mint 20) to see if that produces a more usable version.

Does the normal AppImage work? That is my biggest concern and I was worried that that is what you were talking about in your initial email since you did not specify.

How stupid I am! I thought I downloaded the multibit appimage and not
the line above. However even the multibit version gives me an error:

/home/paz/Desktop/CinGG-20210731-multibit.AppImage: error while
