Hello,
i would expect AUR packages be update also using package manager, but no, these are not updates even with “pamac update”, after searching on SE how to do it, i have not found the solution.
So i read the pamac --help and ended up with this command that appear to may work:
pamac update -a --devel --ignore ungoogled-chromium
but again, too long to remember for me :-/
i remember pacman -Syyu, but does not appear i can use it for AUR.
btw, should i use pamac update for updating system or is better to use pacman -Syyu ? Also asking because apparently pacman fails to suggest optional child packages, while pamac suggest it. So i began using pamac for installation, becaus eobviously when youa r einstalling something you appreciate if you are shown its optional/child packages. Not sure why not default in pacman.
