CIFS Mount error (13) Fix on Ubuntu

Are you running into this error when trying to mount a CIFS (SMB) share using /etc/fstab on Ubuntu?

mount error(13): Permission denied

Error code 13 usually indicates that there is a permission problem, but in many cases, it simply means your system is missing the necessary CIFS utilities to handle the mount properly.

Install the required package with this command:

sudo apt install cifs-utils -y

Also, make sure your /etc/fstab entry is correctly formatted.

For example:

//192.168.1.10/ShareName /mnt/share cifs credentials=/etc/smb-credentials,uid=1000,gid=1000,vers=3.0,noperm 0 0

And ensure your /etc/smb-credentials, or whatever file you use to store your credentials, file contains the correct username and password.

username=your_smb_username
password=your_smb_password
