The upgrade process is designed to do the right thing for users who
stick with our defaults. Manual intervention is required for unusual
cases like this. You'll need to manually disable systemd-resolved
after upgrade, restore /etc/resolv.conf from the backup file that
will be created during upgrade, and restart NetworkManager. That
would look something like:
# systemctl disable systemd-resolved.service
# systmectl stop systemd-resolved.service
# mv /etc/resolv.conf.orig-with-nm /etc/resolv.conf
# systemctl restart NetworkManager.service
After the latest updates, this should not necessary (though it will still work).
Instead, specify a preset (before the upgrade):
sudo bash -c 'mkdir -p /etc/systemd/system-preset && echo "disable
systemd-resolved.service"
>/etc/systemd/system-preset/20-systemd-resolved-disable.preset'
