“Failed to mount the cdrom” just tells you that it failed. You have to look at your syslog

less /var/log/syslog


or open another terminal and run

tail -f /var/log/syslog

before you use “apt-cdrom” to see more specific error messages.

It could be that the CD is invalid, cannot be read, or that the device /dev/cdrom or whatever is incorrect. Then try what amacater suggested.

Hi, I’m not an expert and I don’t understand why my just installed Debian refuses to mount other hard disks.

My computer had XP with Ubuntu. After a failed update I decided to install Debian instead of Ubuntu. All things seemed to go well (I’m writing using Debian) but I can’t open other disks.

If I try to do that I receive the message: “Impossible to mount the volume”.

Can anyone help me?

I installed Debian into the same partitions where I previously installed Ubuntu.

Thanks a lot.

I’m not sure,
But perhaps this problem will be solved with adding a line like the following to /etc/apt/sources.list :
deb cdrom:[CD-LABEL]/ testing contrib main

And then update the cache:
sudo apt-get update

Troubleshooting

Type (as root)

dmesg | grep cdrom

[To find out whether the cdrom device was detected at boot
Assume for the moment that it was /dev/hda Manually mount the device]

mount -t iso9660 /dev/hda /media/cdrom

[Change to the directory and check contents]

cd /media/cdrom ; ls -al

[If you see the contents of the CD, all is OK so far. Change out of the directory]

cd ../

apt-cdrom add

[You should see some message about searching for package listings – this may take some time]

aptitude update

Now synaptic should work.

I routinely use this sort of procedure to install isolated workstations from a set of DVDs before connecting them to a network. If you add all 5 or so DVDs this way, then when you need to install packages you will be prompted to insert the appropriate DVD. Once machines are on the network, remember to edit the /etc/apt/sources.list to remove the DVD entries]
