With sudo gpasswd --add migtorr cdrom > gpasswd: group 'cdrom' does not exist
in /etc/group

sudo groupadd cdrom > groupadd: group 'cdrom' already exists

sudo usermod -aG cdrom migtorr does nothing

sudo chown root:cdrom /dev/cdrom

sudo chmod 660 /dev/cdrom

sudo udevadm control --reload-rules

sudo udevadm trigger

does nothing

Had to edit the /etc/group file and add cdrom:x:24:migtorr

group migtorr > migtorr : migtorr wheel cdrom

And now that part seems to be sorted

sudo chmod 4711 /usr/bin/wodim\ > chmod: changing permissions of
/usr/bin/wodim: Read-only file system

sudo chmod 4711 /usr/bin/cdrdao\ > chmod: changing permissions of
/usr/bin/cdrdao: Read-only file system

I cannot find a workaround for above

ls -l /dev/cdrom > lrwxrwxrwx. 1 root root 3 Mar 17 13:33 /dev/cdrom -> sr0

I try sudo k3b but it crashes:
