please read up bug #1012081 = Applications in the default desktop - specifically gnome-disk-utility - depend on behaviour only introduced in util-linux 2.21+. Specifically if you select "Show in user interface" in mount options, it adds the mount option "x-gvfs-show" to the mount options in /etc/fstab. Mounting of this mount point then fails because the option is unrecognised.
in particular, comment #51 = [...] The fstab entries done by the gnome-disk-utility v 3.10.0 which comes with 14.04.2 are still causing problems at boot. After some try and error I found that the entry in fstab needs to be "...comment=x-gvfs-show..." as opposed to "...x-gvfs-show..." entered by the gnome-disk-utility when "Show in user interface" is checked. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-disk-utility in Ubuntu. https://bugs.launchpad.net/bugs/1520113 Title: disks should not offer x-gvfs-show when Bug #1012081 is still unresolved Status in gnome-disk-utility package in Ubuntu: Incomplete Bug description: As long as bug #1012081 has not been resolved, disks (gnome-disk- utility) should *not* offer x-gvfs-show as default.
