I checked the http://my.archive.ubuntu.com/ubuntu, the url is not found.
Any idea on this ? I am newbie on linux.

(ie. remove the "my." and you'll use the main site managed by Canonical (company behind Ubuntu) instead of your current mirror provided by ONBOARDCLOUD PTE. LTD. The link of available mirrors was provided in my prior comment; you can use any; some are better than others; but all can have issues temporarily. – guiverc Feb 10 '22 at 09:33
