When upgrade succeeds but warnings/errors scrolled by and are missed

[wmorrison]

When an upgrade succeeds, but you saw errors or warnings for some packages scroll by…

(Or didn’t see because you were doing something else and only saw that it succeeded)

Including but not limited to .pacnew files and messages about “manual intervention required,”

Is there a way to show the existing warnings/errors, without manually scrolling back pages and pages in terminal output? (Possibly losing some if buffer is low? Not mine, but could be an issue for some.)

I’ve always found it odd that pacman will emit these messages yet succeed, when often people may not watch the output anyway, except the end where it’s successful or not.

A few excerpts from my latest update. I know how to solve these, that’s not the question, it’s how to be alerted of them when you didn’t notice them scrolling by and the upgrade succeeded.

Look at /var/log/pacman.log. All pacman transactions are recorded there, including errors and warnings.

You can filter it in various ways, in the same way you can filter any text file.

@Stagger_Lee

Look at /var/log/pacman.log

Wow. I’ve been using Arch or Arch-based distros for several years, and somehow never picked up on that, even though looking in /var/logs for other stuff is standard. Thanks for the n00b lesson. (No, seriously, that’s not sarcastic, you gave the answer, and it’s something I should have known.)
