Hi,
I've you've installed or upgraded to Fedora 33 (or to rawhide) prior to
today, your /etc/nsswitch and /etc/resolv.conf are probably in a broken
state that requires manual intervention to resolve. This has caused
breakage for mDNS and VPN users [1][2][3]. Apologies for this breakage.
Anyone installing with current nightly images or upgrading as of today
should be OK, so users installing F33 beta or upgrading from F32 to F33
beta will be unaffected.
To fix /etc/nsswitch.conf, edit the hosts line in
/etc/authselect/user-nsswitch.conf to look like this:
hosts: files mdns4_minimal [NOTFOUND=return] resolve
[!UNAVAIL=return] myhostname dns
Then run:
# authselect apply-changes
Then, fix /etc/resolv.conf:
# rm /etc/resolv.conf
# ln -s ../run/systemd/resolve/stub-resolv.conf
And restart NetworkManager:
# systemctl restart NetworkManager.service
Michael
