After the upgrade my network drive does not mount. fstab //192.168.178.73/Thuis /media/Thuis cifs noserverino,guest,user=,nounix,_netdev,dir_mode=0777,file_mode=0777 0 0 This worked until the upgrade. When trying to mount I get: mount: wrong fs type, bad option, bad superblock on //192.168.178.73/Thuis, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program) In some cases useful info is found in syslog - try dmesg | tail or so. And if I do dmesg | tail, it gives: [ 21.141585] cgroup: new mount options do not match the existing superblock, will be ignored [ 24.103109] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready [ 24.103661] forcedeth 0000:00:07.0 eth1: MSI enabled [ 31.195496] FS-Cache: Loaded [ 31.232146] FS-Cache: Netfs 'cifs' registered for caching [ 31.233761] Key type cifs.spnego registered [ 31.233773] Key type cifs.idmap registered [ 31.234020] CIFS VFS: No username specified [ 327.314333] CIFS VFS: No username specified [ 349.637971] CIFS VFS: No username specified Also see question https://answers.launchpad.net/ubuntu/+question/284714 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: gvfs 1.27.4-1ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-49.55~14.04.1-generic 3.19.8-ckt12 Uname: Linux 3.19.0-49-generic i686 NonfreeKernelModules: nvidia ApportVersion: 2.19.4-0ubuntu2 Architecture: i386 CurrentDesktop: XFCE Date: Thu Feb 11 11:11:57 2016 InstallationDate: Installed on 2016-01-17 (25 days ago) InstallationMedia: Xubuntu 14.04.3 LTS "Trusty Tahr" - Beta i386 (20150805) SourcePackage: gvfs UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1544480/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
