Trying to mount a CIFS network share

Was able to install cifs-utils through apt-get, however when running the mount command, I am getting an error stating that cifs filesystem is not supported by the system.

sudo mount -t cifs \\\\10.10.30.254\\backup\\router -o username=xxx,password=xxxx,vers=3.0 /mnt/config-backup

mount error: cifs filesystem not supported by the system

apt-get reports it is installed

cifs-utils is already the newest version.

As well, the mount.cifs command returns invalid command.

Is this some limitation or am I simply missing something? I have no rebooted yet, perhaps this is the issue. Thanks!

Has anyone figured this issue out? I am also having the same issue and have found no solutions after hours of searching.

Did you try loading cifs module before mount?
modprobe cifs
