Hi all, my Fedora 31 system using NM for wifi shows the following behaviour: From time to time the /etc/resolv.conf file disappears. Even re-connecting doesn't help. I get an IP but no nameserver. What might be the reason? And how to fix? Greetings, Frank Elsner

/etc/resolv.conf is a link to /var/run/connman/resolv.conf which doesn' exist. --Frank Elsner

Sounds like, since I've never used or heard of connman, like there is a conflict between it and NM. dnf erase connman ? -- The key to getting good answers is to ask good questions.

Erased connman, /etc/resolv.conf and /var/run/connman/resolv.conf, rebooted and it looks good/correct. Thanks, Frank

Don't know reasons, but I have used a big hammer to fix things like this: Create the resolv.conf file the way you want it to be, then do: chattr +i /etc/resolv.conf Thus making the file immutable and bypassing all the helpful stuff that tries to change it :-).
