• I cannot mount a DVD
  • MakeMKV Failed to get full access to drive . Make sure that you either have write access to device "dev/sr2, are member of "cdrom" group or have CAP_SYS_RAWIO enabled
  • Attempts to manually mount DVD leads to "mount: /mnt/cdrom: no medium found on /dev/sr1."

What I have tried:

  • CD works fine
  • Replaced DVD drive
  • Made sure my user was part of cdrom
  • DVD works fine in OS X
  • Manually mounting the drive
  • Reinstalling 18.04
  • Installing necessary codecs

Any help would be appreciated.

Running groups returns: <myusername> adm cdrom sudo dip plugdev lpadmin sambashare

  • Which order did you do all these things in? What were the actual results of each? What does lshw say about it?

  • Also, please edit your question and add the output of the command groups from a terminal window. It should show if you are part of the cdrom group or not.

I had the same error message.

In my case, I installed makemkv in Ubuntu by using snap (i.e. by using the Ubuntu Software Store).

To solve the problem, I went into the snap store, clicked on "Installed", scrolled down to the makemkv item, clicked on it, clicked on "Permissions", turned on both of the "Read from CD/DVD" buttons (there were two for me, probably because I have two DVD drives).

I also turned on "Read/write files on removable storage devices" although that may not have been needed.
