We don’t need screen shots - we need members which know how to express themselves using the keyboard. Solutions often present themselves out of the blue - when you take the time to put words on your problem.
PKGBUILD from AUR is your own responsibility.
Use the AUR at your own risk!No support will be provided by the Manjaro team for any issues that may arise relating to software installations from the AUR. When Manjaro is updated, AUR packages might stop working. This is not a Manjaro issue - Arch User Repository - Manjaro
Manjaro does not decide whether you should use any given software or not.
So when you deliberately choose to compile ungoogled-chromium using a PKGBUILD it is your responsibility. You will have to verify the validity of the scripts before throwing an unknown application onto your system.
