我正在使用 Ubuntu 14.04。当我在 nautilus 中打开特定 DVD 时出现此错误。
Error mounting /dev/sr0 at /media/user/L'ECO DEL SILENZIO: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sr0" "/media/user/L'ECO DEL SILENZIO"' 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
我尝试找出问题所在：
