--- Comment #5 from Bernhard Übelacker bernhardu@mailbox.org --- The mounts filesystem is ext4, so I think that is no problem. I was wondering if this might be some network filesystem ...
Depending on what is installed in the install64 prefix, it might be faster to rename and reinstall it?
If I understand you right, from your side this bug can be closed?
