You added a bionic=18.04 source to 21.10 ... why? You don't need to add anything manually. Enabling `universe` repository is as easy as `sudo apt-add-repository universe`.

Not quite clear what you mean. Please add all new information to your question https://askubuntu.com/posts/1370767/edit ...... and never in a comment. ........ I did as my answer says : No issues at all.

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.
