Your system is not supported anymore, you have to upgrade through reinstalling, thats the only option!

Please ensure you've applied all upgrades as per the message; ie. `sudo apt update` to ensure software lists are updated (no errors or warnings were given) then `sudo apt full-upgrade` to ensure all available upgrades are applied. Assuming no error messages or warnings exist there; I'd try again (*if you get warnings of *holds* existing on any packages in messages; you'll need to revert/remove those holds). *Do note there are cases where `apt upgrade` cannot apply all upgrades! which is why you need to use `full-upgrade`*

Comment out the CDROM; which is how installation media is referred to (*even if it was on thumb-drive or modern media; it's referred to as CDROM*). - the following will be helpful; but note HIRSUTE or 21.04 hasn't yet moved to old-releases; so the duplicate link isn't required *yet* (but will be in hours/days) See https://askubuntu.com/questions/42441/how-do-remove-the-cd-dvd-install-as-a-source-for-apt-get-packages-when-install

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
