This happened before Christmas so gave it a rest til after New Years, but it's still happening:
Raspberry Pi 5
Ubuntu 24.04 64bit Server via RPi
Imager. Tried different SD cards and card adapters.
SSH configured ok and PuTTY access successful.
Get same error whether with
keyboard/terminal, SSH eth0 or wlan0.

Why would they? It's somewhere between your Pi and your access point
(and if you have an dedicated internet gateway).
First Question: Can you send me the output of
egrep -v '^#' /etc/resolv.conf
Second Q:
ping www.google.com
For me, that looks like
=================================================================
ubuntu@ubuntu-2404-pi:~$ egrep -v '^#' /etc/resolv.conf
nameserver 127.0.0.53
options edns0 trust-ad
search .
ubuntu@ubuntu-2404-pi:~$ ping www.google.com

=================================================================
You could try to change the 'nameserver line' to use 8.8.8.8 (a public
google DNS server). That might help in the short term (until a reboot or
DHCP refresh).

The problem is, you can't follow that recipe blindly:-( As long, as you
know, what you're doing, it's a good way to go. But there are values in
there, which have to match the local setup.

Team,
Thanks to everyone for the
guidance.
First to answer the suggested queries:
ubuntu@Stingray:~$ ping
www.google.com
ping: www.google.com: Temporary failure in name resolution
ubuntu@Stingray:~$ egrep -v '^#' /etc/resolv.conf
nameserver 127.0.0.53
options edns0 trust-ad
search .
But once it became clear that the
problem was me getting out I figured out the problem is in
/etc/netplan/--.yaml
Using Ubuntu Desktop it's fairly easy to configure etho & wlan0.
But using Server, it means playing with netplan which is a real hemorrhoid with changing documentation and deprecation of commands.
But I adapted /etc/netplan/50-...-.yaml from another Ubuntu machine on my network and all is well!
Thanks again!
Jim
Steve " 'dillo" Okay

It's like the playground they turn the summer interns and new hires loose to experiment and flex their wings on.
