Hi,

It almost looks like the server you're working on does not have any DNS servers configured, as the error says that it can't resolve us.archive.ubuntu.com. I'd check DNS functionality.

No , DNS correctly configured and prior to this i have configured KVM on Ubuntu and it was resolving perfectly fine.

I don't know what to tell you, the message clearly says it can't resolve the ubuntu repository URL.

Try verifying your DNS server and if possible, add alternate DNS servers (like 8.8.8.8, if your system is internet connected).
