I agree. I’m former windows user and I prefer GUI but just to be on a safe side, my procedure is now always like this:
(wait until I see over 100 votes)
1 - just download packages first, without installing anything:
sudo pacman -Syyuw
2 - log to TTY and from there run the update:
sudo pacman -Su
If votes/comments indicate any possible problems then I reboot after first step and at grub prompt use append “3” to log into clean TTY and update it from there.
