I fixed this on my system by adding a udev rule. You could simply add the necessary line in 40-permissions.rules but if there is an update to udev it will get overwritten and you'll be back where you started. So I created a new rule and called it 15-local.rules and put the following lines in the file:
# SCSI devices BUS=="scsi", KERNEL=="sg[0-9]", NAME="%k", GROUP="cdrom" Restart the system and in terminal run cdrecord -scanbus. You should no longer see the line"Error trying to open /dev/sg0 exclusively (Permission denied)". -- cdrecord maps <bus>,<target>,<lun> to /dev/sgX imperfectly https://launchpad.net/bugs/23203 -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
