I can tell you what I do, but I will tell you now, nobody is going to like this advice and hopefully I don’t get permanently banned off the forum for this, but…
I use Pamac to let me know when updates are available. You get this
telling you there are updates to fetch and install, and you get this when everything is up to date.
I also use it to download all the updates in the background while I’m away from my computer since my DSL line sometimes gets slower then a 1980ies style 9600 bps dial up modem. This way when I do my garuda-update --aur
I can review everything before installing the packages. It will fly through the install because everything is stored locally on the hard drive for you.
One thing you should know is to never install your updates from this program and make sure the settings in the program are not set to auto-install on shutdown. Always update from your terminal window.
I have been told in this previous forum post above that this is like cocaine for your computer, so do you want to join the party? We can live like rock stars!
