After adding 'client min protocol = NT1' to ~/.smb/smb.conf I could indeed mount the disk via Nautilus, but that revealed another bug: most files are seen as Directories instead of files (pdf, txt and so on), but give an error when I try to open them.
I tried some more: A MOUNT with the CIFS option gives access to the disk and I can read and write all files. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879776 Title: ubuntu 20 error mounting smb drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1879776/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
