ISSUE DESCRIPTION

I installed Ubuntu 20.04.3 LTS yesterday. When I connected to the internet, Ubuntu showed a message with available updates, so I updated my software.

The problem is that I cannot get any of the following burning applications (mentioned below) to write to a disc.

There are currently no issues with my Ubuntu installation.

I'm learning how to make audio music CD's, so I installed K3b, Brasero, and Xfburn trying to test my DVD writer on Linux, but all three of these applications failed at writing DVD or CD discs. At one point, I received an error message that writing isn't supported.

I used my laptop writer before when I was using Windows to burn some CD's and I made it successfully.

WHAT I'VE TRIED

I tried some solutions shown in some other askubuntu qustions but, there's no result.

I checked my DVD writer with this command:

pascal@pascal-Lenovo-ideapad-330-15AST:~$ cat /proc/sys/dev/cdrom/info

Many device access problems can be resolved through group membership changes.

Specifically, if ls -l shows that the group permissions (the second "rwx" triplet) is "rw" (e.g."-rw-rw----"), then, adding oneself to the group that owns the device will grant rw access.

Here's how:

device="/dev/whatever"
# in your case
device="/dev/cdrom"
sudo adduser $USER $(stat -c "%G" $device)

This allows you membership in the group that can rw the device, but there is one more step.

To make all your processes members of the new group, logout and login. Group memberships are set up at login time.

To create a single process in the new group (for testing, prior to logout/login):

newgrp $(stat -c "%G" $device)

or, just type the group name. See man newgrp.
