`eoan` is Ubuntu 19.04, which is not anymore supported. The output also shows bionic (18.04), whereas you said it is 21.04. Please clarify your release. Don't mix repositories between different versions of Ubuntu. Don't make a [FrankenSystem](https://wiki.debian.org/DontBreakDebian)

Assuming that you ARE running Ubuntu 21.04...

Note: Your system may not have updated/upgraded properly in the past.

Note: If you have any difficulties with these instructions, stop, and ask for help.

Edit two files...

sudo -H gedit /etc/apt/sources.list

deb http://us.archive.ubuntu.com/ubuntu/ hirsute main universe restricted multiverse
deb http://archive.canonical.com/ubuntu hirsute partner

Change bionic to hirsute like shown in the above two lines.

Save the file and quit gedit.

sudo -H gedit /etc/apt/sources.list.d/dropbox.list

deb http://linux.dropbox.com/ubuntu disco main

Change eoan to disco like shown in the above line.

Save the file and quit gedit.

sudo apt update

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.
