[SOLVED] DNS broken after system update

Swordz · 2022-01-05 20:33:42

So I just updated my system with pacman -Syyu etc. the normal stuff. I use networkmanager for my networking btw. Now my DNS seems to be broken as I cant connect to any other sites than google ones and archlinux.org. The error it returns is DNS_PROBE_POSSIBLE (on brave(chromium). What could possibly cause this problem? Ask me to paste logs if needed (I dont know what I should post)

I have solved the problem but unfortunately only through bloat known as gnome settings. I removed my current network profile and added a new one. This fixed the problem but I wonder was it worth installing bloatware for that. Yes.

"pacman -Syyu" isn't "normal" but an approach to invalidate your package database and harass the used mirror (see the manpage what the second "y" actually does and then stop using it) and no, there was certainly no reason to install gnome to configure your network.
It's also questionable whether re-creating a network profile could possibly have "fixed" DNS issues, what raises the question whether those were/are DNS issues at all or alternatively, whether you coincidentally restarted systemd-resolved (assuming it's in use) eg. through a reboot and it's now responding again.

Relevant informations if this creeps up again would be

stat /etc/resolv.conf
cat /etc/resolv.conf
cat /etc/nsswitch.conf
ip a
ip r
dig example.com
dig @8.8.8.8 example.com

Since the common cause for weirdnetworkissue are concurrent network managing daemons, feel free to post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

for a sanity check.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Yeah I mean pacman -Syu but misstyped srry. But thanks for the help. I was in kind of a panic because you know I had no internet access
