Manjaro and aur are not a good idea. I ran manjaro for a year or two. Things from the aur were constantly breaking and causing problems because of the manjaro repositories. If they were even able to be installed at all. There are many reasons not to use Manjaro. But if you want to use the Aur. Check out endeavor os. Very straightforward simple easy to install Arch. The Aur works perfectly and doesn’t break randomly. Because they use the Straight Up Arch repositories with just slightly different configs
