Public bug reported:
After having updated my laptop from Ubuntu 17.04 to 17.10, the DNS
lookup on my wireless network connection did not work any more.
As it seems, the file /etc/resolv.conf was static and contained wrong
data assigned by the NetworkManager. When I changed the file content
manually to
nameserver 127.0.0.53
DNS lookup worked fine. After reboot, however, I had to repeat this
operation since NetworkManager seems to have replaced the file content.
Finally, I found a solution. Running
sudo dpkg-reconfigure resolvconf
the file /etc/resolv.conf was replaced by the link
/etc/resolv.conf -> ../run/resolvconf/resolv.conf
Now, the wireless network seems to work properly.
Hence, there must be some kind of bug during the update process from
Ubuntu 17.04 to 17.10 that impedes resolvconf to be configured properly.
Best regards,
Artur
