I have been trying to install Matlab on Ubuntu.

The issue starts even prior to the installation, as mounting the .iso file results in the following error:

mount: block device /home/marta/Downloads/R2013a_UNIX.iso is write-protected, mounting read-only

When typing blkid I get:

/dev/loop1: LABEL="MATHWORKS_R2013A" TYPE="iso9660" 
/dev/sda1: UUID="CB61-A2F3" TYPE="vfat" 
/dev/sda2: UUID="3a6abc2f-f83c-4c52-84f9-f10cbae59ada" TYPE="ext4" 
/dev/sda3: UUID="27362882-2d21-47ea-a65a-27102e6dea1e" TYPE="swap" 

So it is there, but all as read-only and hence I can't use it. How do I resolve the issue?

  • The answer by a-donda is spot-on. This means that the error is not an error, just a warning. – roadmr Feb 3 '14 at 18:37

ISO 9660 is a read-only file system, because it was designed for read-only media (CD-ROMs). This shouldn't pose a problem for installation though, because during installation the installation medium is only read and not written to.

Mount the image read-only to a folder (e.g. /mnt), open a terminal and change the working directory to that folder, then start the installation program. Everything should be fine.

    I did that before, but all I get is a series of Input/output errors. For example cp: reading '/some/path':Input/output error cp: failed to extend '/same/path/as/above':Input/output error Hence I thought it was related to the mounting error... – user234356 Feb 4 '14 at 21:51
  • That's strange. Maybe something went wrong while downloading the file? If you're sure that's not the case, it would be good to include a verbatim copy of all the commands you used and all the messages you got in the question. Use the edit link below your question to do so. – A. Donda Feb 5 '14 at 1:04
