18.04k3bpermissions
I have this problem with k3b in 18.04 releases (Ubuntu, Kubuntu, KDE Neon…) In oldest releases I do not have this problem:
cdrecord has no permission to open the device
You may use K3bbsetup to solve this problem.
I've searched online but I have not found any solution.
Can anybody help me?
I had similar problem and fixed it with the following steps:
It will ask for your password (you must be admin).
If it doesn't works, open k3b from terminal with sudo -H k3b, and try same steps as before.
Should help.
Fixing the 'burning group' error:
I can confirm this issue with Ubuntu 14.04 and k3b run as either ordinary user or running with sudo k3b. The solution on my system was to manually create the group from the commandline before opening k3b, demonstrated on my system as follows:
andrew@corinth:~$ sudo addgroup burning
[sudo] password for andrew:
Adding group `burning' (GID 1001) ...
Done.
andrew@corinth:~$
After this add yourself to the new 'burning' group:
sudo usermod -a -G burning $USER
And then going to the k3b configuration screen:
k3b --> Settings --> Setup System Permissions
and checking all of the following boxes:
Press 'Apply' and all should now be well :).
Further Error Messages?
If however you managed to create the required group but continue to get odd burning problems and errors consider adding Brandon Snider's CDRTools PPA:
sudo add-apt-repository ppa:brandonsnider/cdrtools
sudo apt-get update
And then installing Jörg Schilling's cdrtools and friends (this will safely replace the Debian fork burning tools):
sudo apt-get install cdda2wav cdrecord mkisofs
And finally returning to:
k3b --> Settings --> Setup System Permissions
to setup the new applications with the appropriate permissions.
Another few things to try if problems persist:
Finally here is a screenshot showing the final settings on my own system:
Best Answer
Try attempting the following commands:
This will set the UID bit on the necessary binaries. It is illustrated in Settings -> Configure k3b -> programs -> Permissions "tab".
