AFAIU, the work on SMBv3 UNIX extensions on Samba is ongoing: https://wiki.samba.org/index.php/SMB3-Linux
So, while cifs-utils tries to use "unix" when mounting the share, Samba still doesn't support it, and therefore mount.cifs falls back to nounix. This is not necessarily a bug; it's just something that is still being developed and will ship in future versions of Samba. I am moving this bug to the samba package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882980 Title: unix extensions disabled by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cifs-utils/+bug/1882980/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
