    Can't mount an iso file in ubuntu 12.04

    I am trying to mount a 5.8GB .iso file, first I used "gmount" but it gave this error "An error occured In some cases useful info is found in syslog - try dmesg | tail or so"
    Then i tried "Furious iso mount", after mounting the mount point was empty !!
    help please

    What is the command you are using? The following works for me:

    Code:
    sudo mount -o loop /path/to/file.iso  /path/to/mount/point

    It says :

    can't find "directory" in /etc/fstab or /etc/mtab

    the command :

    sudo mount -o loop /home/khalid/ml2011au.iso /home/khalid/mountPoint

    that what it says now :

    mount: you must specify the filesystem type

    never mind what it said before (i guess i didn't write the command correctly)

    Add -t for type:

    Code:
     sudo mount -t iso9660 -o loop /home/khalid/ml2011au.iso /home/khalid/mountPoint

    It gave this :

    mount: wrong fs type, bad option, bad superblock on /dev/loop0,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so

    May be a corrupt iso, did you create it yourself or is it downloaded? Have you tried checking the md5? If you right click the iso in nautilus are you able to open the file with Archive Manager?

    I downloaded it, when i open it with archive manager it says "CD-ROM is NOT in ISO 9660 format"
    i guess it's corrupt :S

    and whats "md5" ?, I am new to ubuntu and trying to learn as much as possible.

    md5 is a method of creating a checksum for a piece of data. The checksum is always 128 bits long (I think), and the chances of two different bits of data (or a corrupt iso image) giving the same checksum are billions to one against. So calculating and comparing the md5 checksum is a good way of verifying that the image is good (or not).

    The command md5sum is installed by default in Ubuntu:
    Code:
    md5sum ml2011au.iso
    will print the checksum for your image. Compare that with the checksum that the site you donwloaded it from says it should be.
