Was working beautifully until today, and I don't think I changed anything to cause this.

why in the world did you change and comment that out? Where are the new entries you were supposed to merge from the .pacnew?

The uncommented 'SigLevel' is near the bottom of the file.

I just copied those files over and uncommented a server. It's still not working.

The uncommented 'SigLevel' is near the bottom of the file.

And due to that, it is being handled as part of the [extra] section, not the global section. Move it above [core].

However, as noted by Scimmia, your pacman.conf is missing a significant amount of options, commented or otherwise. However you handled the pacnew files, it left you with a mangled pacman.conf. Read up on https://wiki.archlinux.org/title/Pacman … nd_Pacsave

That fixed the issue. Thanks. Strange that it worked for so so many years.

I'm not sure what a regular pacman.conf looks like. I've been using it like this for years.

It doesn't sound like you have been handling your pacnew files at all. If not, you should get into the habit of dealing with them as they are created to avoid any unexpected behaviour like this.

The pacnew version that was installed as part of the update is what an unmodified version of the file should look like. If you have somehow deleted that version, you can re-extract the default file from the archive, e.g.

$ bsdtar --strip-components 1 -xf /var/cache/pacman/pkg/pacman-7.1.0.r7.gb9f7d4a-1-x86_64.pkg.tar.zst etc/pacman.conf

Then compare that file with the one you are using and merge the two files together.

I hadn't given it any thought... I replaced my /etc/pacman.conf with the updated version and added back the chaotic repo, and it worked fine. Nice to see the new options in there!

Thanks! This is great information to know. I'll be sure to keep it up to date for now on.
