I don't speak German very well but if I understand correctly your /home/$LOGNAME is a symbolic link to /Users/$LOGNAME. This arrangement is not supported by snapd as it interferes with the sandbox technology.
If you can, modify your system to mount the home directory at /home/baer instead of using symbolic links. This should fix this issue entirely. ** Changed in: snapd (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061832 Title: Firefox startet nicht To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2061832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
