Thanks I have been using Manjaro for a few years now and like it, but didn't know about those issues. Like how aur scripts are not checked. Maybe it's time to switch around again.
The only reason I switched from Mint to Manjaro was that my new laptops video card wasn't supported (like mint wouldn't boot). But that was a few years ago, so it's probably not an issue anymore.
I used to like Ubuntu but hated Unity and hate snap.
Another train on fire?
