Arch Linux Updates and Keyrings (key error)
Package managers are awesome, Windows 10 is finally getting one. I've loved apt, pacman, yum and the like ever since I had a stable internet connection.
Package managers just spare you from grey hair and having to visit a lot of websites to download all kinds of things and then click all of them. It downloads, installs and leaves you the hell alone with things a computer should be able to do on its own.

Basically this ensures that you have the up to date keys for your derivative. If you run manjaro it would be

The whole reason I needed this was to fix a buggy version of something that had to do with pandoc and creating .pdf from markdown, so I'll probably share a script about that soon.
