Проблемы при монтировании привода с различными типами CD-DVD дисков. Error mounting system-managed device /dev/sr0: Command-line `mount "/media/cdrom0"' exited with non-zero exit status 32: 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.
В /etc/fstab имеем строку:
/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto 0 0
При попытке монтирования из консоли:
# mount /dev/sr0 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.
При попытке открыть в файловом менеджере "Thunar 1.6.11" кликнув по серому/блеклому значку привода на рабочем столе:
Не удалось подключить «MyDVD»

dmesg | tail or so.Список доступных "fs type" мы можем глянуть выполнив ls /lib/modules/$(uname -r)/kernel/fs
Успешно сработало ручное монтирование с явным указанием файловой системы:
Только после полного отключения блокировщика скриптов и рекламы на этом месте появится полезная подсказка/ссылка/код/пример конфигурации/etc!
Поменяв в /etc/fstab местами перечень файловых систем с "udf,iso9660" на "iso9660,udf" проблемный DVD-диск стал успешно монтироваться как из консоли так и при открытии его в файловом менеджере, - однако перестали монтироваться обычные CD-диски в формате "iso9660" :)
Сейчас я процитирую юзера Daniel, как позже выяснится, рапортовавшего про сей баг ещё в далёком 2006-м году: "Складывается такое впечатление, что только последняя запись из списка fstype разделённых запятыми работает"
Bug #44233 “mount udf dvd fails, possible wrong fstab entry” : Bugs : util-linux package : Ubuntu
After mounting it shows a perfectly mounted udf file system.
/dev/hdc on /media/cdrom0 type udf (ro,noexec,nosuid,nodev,user=daniel)
By the way: Changing fstype in /etc/fstab to "iso9660,udf" (turning it around) makes udf dvd work and iso9660 file systems like normal CDs don't work anymore.
So it seems that only the last entry of the comma-separated fstype list works.
Решением проблемы является замена в /etc/fstab fstype с "iso9660,udf" на "auto" и да прибудет нам счастье. Возможности своего CD-DVD можно посмотреть коммандой wodim -prcap
