Failed to setup loop device while mounting .iso file

Question

I am trying to install Matlab R2013A in Ubuntu 15.04 using an .iso file and:

• I logged in as super user using sudo su.
• I made a directory for a mount point using "mkdir -p /mnt/disk"
• To mount the .iso I used: mount -o loop Matlab_801_R2013a_MacUnix /mnt/disk

but got the following error:

mount: Matlab_801_R2013a_MacUnix: failed to setup loop device: No such file or directory  

Could someone please explain me what is a loop setup and how I can solve this problem?

Solution

You need the complete path for your iso file:

mount -o loop <path_to_iso>/Matlab_801_R2013a_MacUnix.iso /mnt/disk

And .iso files usually have an extension. Check that and note the correct spelling of the file..

What is the exact iso file name and location ? You may need to add .iso at the end of the file name and include the exact path if the iso is not in the current directory.
