I am currently using the Ultimaker Cura that one can install via the Software Centre which is currently in version 4.8. However, there is a more recent version of the software available here (that is version 4.11). I can download the AppImage and run it but I just want to add a repository so that the newest release automatically replaces any old version.
Can anyone help me assemble the line: sudo add-apt-repository ppa:...
if this is possible from the code available on the site above. Not even sure if this is possible.
