Manual intervention required: broken /etc/nsswitch.conf and /etc/resolv.conf for F33 early adopters

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
