I’m not sure what I did before, but now I can’t run apt-get update. Any ideas on how to recover from this?

sudo apt-get update

No. I tried that already

But what did work was `sudo apt-add-repository -r https://cli.github.com/packages`

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.
