When I re-watched the video, I found myself accidentally saying Brasareo. This fix is for K3B only.
If you have this issue in Ubuntu 18+, this same procedure might fix it as well. I don't know for sure, but since Ubuntu and Linux Mint are Debian releases, I'm thinking it should work.
Terminal Commands for K3B Permissions Fix
sudo chmod 4711 /usr/bin/cdrdao
sudo chmod 4711 /usr/bin/wodim
sudo chmod 0755 /usr/bin/growisofs
