Missing Release file when running SUDO APT UPDATE in 20.04

in flag

I just ran sudo apt update, as the first step in upgrading from 20.04 to 22.04. This was part of the response:

Get:17 focal-updates/main amd64 DEP-11 Metadata [275 kB]

Err:11 focal-getdeb Release 404  Not Found [IP: 443]

Get:18 focal-updates/universe amd64 Packages [1,046 kB]

... I've skipped a few lines here...

Get:33 http// focal-backports/universe amd64 c-n-f Metadata [880 B]                                                
Reading package lists... Done                                                                                                                   
E: The repository ' focal-getdeb Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

OK. So why is the update trying to use https when the path in my Software & Update settings is

Thank you David. I don't know how you narrowed it down, but even the one with an answer has a lot of branches and potential options. In particular, the comment "To summarize, you need to remove the added PPA, and use another one that has packages for your particular release." appears helpful: but I don't know if there is an suitable alternative PPA (or how I would choose it), or whether it would be safe to just deselect the existing one.
I sit in a Tesla and translated this thread with Ai:

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.
