I have just moved from Windows to Ubuntu. Before I uninstalled windows I put some documents that I needed on a CD. Once I had installed Ubuntu I put the CD in to get the files back. But all I get is the message...
Error mounting /dev/sr0 at /media/chris/UDF Volume: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sr0" "/media/chris/UDF Volume"' exited with non-zero exit status 32: mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
People are not going to migrate from windows if Ubuntu can't even do a simple task like open a CD without this meaningless error message.
