Are you seeking support? or trying to report a bug. Your *support question* reads more like a bug report to me, and this isn't a bug tracker. Refer https://help.ubuntu.com/community/ReportingBugs for details on reporting bugs, but if you have trouble with the `ubuntu-bug` tools, you can always file the report online with launchpad, then add additional details using `apport-collect` later from the impacted box (*this would appear to get around the problem picking a package somewhat as you're selecting that online with a browser yourself*).

You may have included some details for sure, but still weren't very specific. Ubuntu has many ISOs available, and 20.04.1 narrows it done some, but even then not clearly. There are desktop, server & flavors involved, plus many *daily* images that may also be treated as 20.04.1 thus the specific ISO is recorded in the format YYYYMMDD.9 (the .9 may not exist; it's added for second/third/etc extra ISOs built on the same day). Those figures can vary on ISO, eg. 20220809 is the released 20.04.1 Desktop for *amd64*, but not all released ISOs had that date, some .1 & you may mean something else too

If you're trying to report bugs, please us a bug tracker that will be seen by *developers* of Ubuntu, and not a user-support site only seen by end-users.

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.
