Thanks, Luk. According to below snippet that automatically was attached to your bug report, the trailing slash is not in /etc/fstab? Sorry, I've tried different variants of fstab to fix the issue, so that there is no trailing slash in the first line of the attached fstab. But the mount behavior is the same for all of the nfs entries in my fstab. Best regards, Pavel -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#653630: /sbin/mount.nfs: Re: nfs-common: Only root can unmount, nautilus badly confused
There was two problems after update, but the first one (umount: /mnt/library mount disagrees with the fstab) can be easily solved by the trailing slash. The reason why I mentioned it here is that it may be useful to know that it came along with the main unsolved problem with the user option (umount: only root can unmount liveserv:/mnt/library/ from /mnt/library). So the problem is related to user option.

Bug#653630: /sbin/mount.nfs: Re: nfs-common: Only root can unmount, nautilus badly confused
I've tried: - /run/mount/utab is empty even when my NFS share is mounted by user. - corresponding entry in /etc/mtab is liveserv:/mnt/library/ /mnt/library nfs rw,relatime,vers=3,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.1.104,mountvers=3,mountport=46570,mountproto=udp,local_lock=none,addr=192.168.1.104 0 0 and it's indifferent to the trailing slash in /etc/fstab. But if there is no trailing slash in the fstab, another error message accurs umount: /mnt/library mount disagrees with the fstab (in this case fstab and mtab entries are different). - if you mount a filesystem with the user option, the user who mounted it will be written to /run/mount/utab.
