Why do I get "wrong fs type, bad option, bad superblock" error?

When mounting an NFS directory by doing:

sudo mount 192.168.1.5:/home/shared /mnt/common

I get the following error:

mount: wrong fs type, bad option, bad superblock on 192.168.1.5:/home/shared, 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.

The kernel is up to date.

The question was already asked (for example here and here), but are either not answered or the answers are not helpful in my case.

What is wrong?

Solution 1:

The error message mentions:

(for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program)

This is relevant given that you are trying to mount NFS. The /sbin/mount.nfs helper program is provided by nfs-common. You can install it with:

sudo apt install nfs-common

On the other hand, if you are trying to mount CIFS, the helper program is provided by cifs-utils. You can install it with:

sudo apt install cifs-utils

Solution 2:

Make sure mount.cifs is listed into /sbin:

ls -l /sbin/mount.cifs

Check to see if package cifs-utils is installed:

dpkg -l cifs-utils

If it isn't, install the cifs libraries with

sudo apt-get install cifs-utils

Solution 3:

It appears that nfs-common package should be installed in order to be able to mount NFS directories.

sudo apt-get install nfs-common

When it's not, the mounting of an NFS directory results in the error I've got.

Solution 4:

I solved it by installing virtualbox. Do

sudo apt-get install virtualbox-guest-utils

It installs the mount.vboxsf

Solution 5:

Try:

mount -t nfs 192.168.1.5:/home/shared /mnt/common
