Test
1. Start Software-properties. E.g. sudo software-properties-qt
2. Navigate to Other Software (Tab), Add -> Add, to add a PPA
3. Insert the PPA string. E.g. "deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu cosmic main "
4. Click Okay.

The software sources list does not contain the new field. Executing in terminal results in the following error message.
