@cscs, you’re right. I got in the habit of doing that after my monthly or so system maintenance. Including this:
UPDATE ARCH MIRRORS:
reflector --protocol https --verbose --latest 25 --sort rate | sudo tee /etc/pacman.d/mirrorlist
UPDATE CHAOTIC AUR:
rate-mirrors chaotic-aur
UPDATE EOS MIRRORS:
eos-rankmirrors --verbose
ATER UPDATING ARCH MIRRORLIST, UPDATE SYSTEM:
yay -Syyu
I’ll keep in mind to do yay -Syu in between. Thanks for the reminder.
Just typing yay is the same as typing yay -Syu:
If no arguments are provided ‘yay -Syu’ will be performed.
See man yay.
in the @anon63071375 's write up, it went reflector command, -Syyu, eos-rankmirrors --verbose, another -Syyu(then nuke journalctl and pacache stuff).
I always wondered when he wrote this monthly maintenance if sequence had any importance (?) or it was simply random? I do it like he wrote it, but now I’m wondering…perhaps he will answer.
/because I have to agree with Uncle’s advice to op that while I do yay daily, you need to get in the habit of the monthly. this has never done me wrong./
Since I run Arch Linux, the command sudo pacman -Syu is all I need.
Then again, that doesn’t seem to work on my Debian machine! 
I have an alias for pacseek -u, which shows upgrades when opening. It also shows Arch news at the same time, so I can react if needed. In pacseek, the update command is eos-update --aur. Ctrl-U runs the command.
checkupdates
and
yay -Syu
just yay
like daily
I think I was following along on the arch maintenance page. I wrote that years ago now though and haven’t looked it over for this reply so I have no real idea anymore.
Same here 
Cheers!
