I'm on Xubuntu 64 bit 14.04. When I had windows 7, I burnt a CD, it was like 4 months ago, now I need to open that CD in Xubuntu, since I no longer have windows.

enter image description here

Solution 1 (didn't work)

sudo apt-get install libudf0

Solution 2 (didn't work)

sudo chmod 777 /media

PS: I won't try ashish's solution unless someone confirms that it will work because mojo706 said that it didn't work.

Solution 3 (didn't work)

▶ sudo mount -t udf /dev/sr0 /cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can't read superblock

dmesg output

Looks like the disc may be no good. Check dmesg for more details. – psusi Apr 21 '14 at 18:41
@psusi I included that in my answer – Lynob Apr 21 '14 at 18:44
Can you mount other dvds in that drive? Either the disc or the drive seems to be broken. – psusi Apr 21 '14 at 18:49
@psusi yes many CDs/DVDs work but I don't know if they are in UDF format or not, I've seen the UDF error a couple times – Lynob Apr 21 '14 at 18:58
I'll try it on my brother's windows 7 laptop and update the question – Lynob Apr 21 '14 at 19:06

I got this and could manually mount the disc as iso9660 instead of udf. I think a recent update in Ubuntu must have change the default for dvd media

sudo mount -t iso9660 /dev/sr0 /mnt
