When ever I tried to run this command “sudo-apt update” I get following errors:

I don’t understand all these issue most of them has “groovy Release no longer has a Release file.” My question, what is the reasons for these issues and how can I fix them. I tried some solutions like change file in ‘/etc/apt/sources.list.d/*.list’ but its not fixing the issue infact its creating more issues.
