I just did the upgrade from 17.04 to 17.10, however my wifi Internet no longer works. I,m on a Thinkpad T430. A simple ssh gets "Could not resolve hostname..." Please advise.

Panther - update from comments:

ping 8.8.8.8 works with a round trip of, e.g., 21.6 ms. ping google.com does not

It sounds very likely you're dealing with the same DNS issue in this question:

DNS not working after upgrade 17.04 to 17.10

Juho-Miko's answer fixed things for me, I've summarized it here as it might be a little difficult for non-technical users to find/follow his answer:

  1. Confirm the issue is that /etc/resolv.conf is pointing at the wrong spot by running:

    $ systemctl status resolvconf

    You should see the following in the output of the command:

    resolvconf[623]: /etc/resolvconf/update.d/libc: Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf

  2. If you do not see the above output, this is NOT your problem. Do NOT proceed to step three.

  3. Run the following commands to fix the issue:

    $ sudo mv /etc/resolv.conf /etc/resolv.conf.old
$ sudo ln -s /run/resolvconf/resolv.conf /etc/resolv.conf
$ systemctl restart resolvconf
