I've just seen this issue after upgrading from 16.04 to 18.04. Burning DVDs worked but burning CDs didn't.
I worked around it via https://askubuntu.com/questions/1032903/problem- with-k3b-in-18-04-releases-cdrecord-has-no-permission-to-open-the- devi/1034927 with a sudo chmod 4711 /usr/bin/wodim; sudo chmod 4711 /usr/bin/cdrdao That did the trick and now allows me to also burn CDs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/510505 Title: cdrecord has no permission to open the device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cdrtools/+bug/510505/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
