[SOLVED] upgrade mga2 -> mga3 mounting DVDs is impossible

[magfan]

After upgrading from mga2 -> mga3 I cannot mount CDs and DVDs anymore.

[doktor5000]

How do you mount them? Is there an fstab entry for the optical drive?
Please show output of

Code: Select all

ls -al /dev/sr*
ls -al /dev/cd*
ls -al /dev/dvd*

and content of /etc/udev/rules.d/70-persistent-cd.rules

The udev rules look weird, how are those CD/DVD drives connected? I'd move that rules file away, it will be recreated on next boot.
Also please remove/uncomment both fstab entries, they are long deprecated/cumbersome.

I removed the udev rules file and both entries in fstab. Now I can use the CD/DVD drives again. Although a new "70-persistent-cd.rules" file has not been created after reboot.

[doktor5000]

Well, i'm not sure with all those changes. udev rules have moved to /usr/lib/udev/rules.d/ or maybe this is even handled by udisks/udisks2 now,
and the old udev rules were still being used and blocked access. Mysteries

[jiml8]

Ultimately, supporting and maintaining a system becomes more difficult as the configuration stuff migrates out of /etc. This applies to systemd and now, apparently, to udev.

[doktor5000]

Well, not exactly. systemd has system-rules/-settings which are under /usr/lib, which are being overruled by those in /etc which is traditionally the admin realm.
Same applies for udev, as you can see from this thread - rule in /etc was actually cumbersome.

But yes, stuff definitely gets more complex - not necessarily more complicated.
