I am trying to mount a CD Rom with an ISO9660 file system. Udisksctl thinks it is unmountable, yet the mount command works:

udisksctl mount -b /dev/sr0
Object /org/freedesktop/UDisks2/block_devices/sr0 is not a mountable filesystem.

However, the Linux mount command mounts it just fine:

sudo mount /dev/sr0 /mnt/
mount: /dev/sr0 ist schreibgeschützt, wird eingehängt im Nur-Lese-Modus
jr@erwin:~$ ls /mnt/
012-RobotsDawn.mp3 014-RobotsDawn.mp3 016-RobotsDawn.mp3 018-RobotsDawn.mp3 020-RobotsDawn.mp3 022-RobotsDawn.mp3
013-RobotsDawn.mp3 015-RobotsDawn.mp3 017-RobotsDawn.mp3 019-RobotsDawn.mp3 021-RobotsDawn.mp3

happens to some CDs of the set I am trying but not to all.

Additional info:
* package version(s)
* config and/or log files etc.

What is mount saying? Set LC_ALL=C and run it again.

mount: /dev/sr0 is write-protected, mounting read-only

I cannot reproduce the issue. Is it still valid for you?
