I want to upgrade my Ubuntu 20.10 to ver 21.04. Using the "Software Updater", the upgrade did not proceed and showed an error. What should I do in order to upgrade my current Ubuntu version?

Error during update .....

"bionic" sources are 18.04, not 20.10. Why do you have 18.04 sources on a 20.10 system?

You haven't said if this is a desktop or server system; if it's a desktop system (esp. given the messed up sources you've posted that do **not** belong on a *groovy* system), I'd just *upgrade via re-install*, ie. install & use existing partitions & do **not** format any. It'll cause your packages to be noted; erase system directories (not *great* for some server apps - but I said desktop, install system & then add-back the *manually installed* packages if available in new release. It won't touch user file/configs (unless format is used) & asks to reboot.

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.
