Unable to upgrade Ubuntu from 20.10 to 21.04

cn flag

I can't upgrade Ubuntu from 20.10 to 21.04: after launching update-manager -c I constantly see strange error:

Your python3 install is corrupted. Please fix the '/usr/bin/python3' symlink.

Anyone have any idea why this happens? I remove all alternatives for python and python3 already. /usr/bin/python3 links to /etc/alternatives/python3, and last one links to /usr/bin/python3.8. Analogously /usr/bin/python links to /etc/alternatives/python, and last one links to /usr/bin/python2.7.

Maybe reinstall python3 package?

Why would there be any link to python2.7? Releases later than 19.10 do **not** include any references to python2 as it's EOL so I'm guessing you haven't restored the links back to default. (*if you added python2; links to it will only be from python2 you don't mention*)

@guiverc Before python symlinks linked to `/usr/bin/python3.8`, I've just tried another possibility) Anyway, it doesn't work

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.
