Failed to connect to https://changelogs.ubuntu.com/meta-release-its. Check your Internet Connection or proxy settings

seems like an error with the DNS-setup of your guest?
* if it's a container add a working DNS-server in the GUI
* if it's a VM configure DNS inside the VM (add a working DNS in /etc/resolv.conf)

I hope this helps!

try changing 'servername 127.0.0.1' to 'nameserver 8.8.8.8' - not sure how the servername got added there - that looks wrong

i change and i typed netplan try, if i ping same error up temporary failure.
