Arch Linux Update Helper

Keeping your Arch Linux system up to date is a good habit, and something you should definitively be doing. It can however become time consuming (specially if you do it on a weekly basis), reason enough to postpone it for too long.

This script will guide you intuitively through the update process, tidy after it, and also optimize your pacman package manager.

Optimize Archlinux's Pacman

Pacman is a packet manager used by Arch Linux and all it's derived distributions. It is the equivalent to apt-get from Ubuntu, and as all packet managers in Linux, allows us to easily install most common, and sometimes uncommon, packets (program) without needing to scour the web for them as in other operating systems.

Pacman is already really fast and many people think it the perfect package manager (me included). However, you can tweak it's performance even further.

For spanish readers, take a look at [frikinux]'s post. He's who told me about reflector, which we will use to get faster downloads from closeby mirrors.

Solving Antergo's "Signature is unknown trust"

Antergos is a Linux distribution based on ArchLinux, in a similar fashion of how Ubuntu is based on Debian.

If you are using Antergos, you will have noticed errors due to wrong or unknown authentication keys when performing a full-system update, with an error message similar to "Signature is unknown trust". Luckily this is quite simple to solve.
