Public bug reported: A not-uncommon bug for Subiquity is one that looks like LP: #2105480, but we have seen many like it and that's just one example. In summary, some files will fail to download from the mirror with the message "Mirror sync in progress?"
For reasons I don't understand just yet, it seems /var/lib/apt/lists can get into a bad state. `apt-get update` just produces the "Mirror sync in progress?". The way to recover from it is to remove /var/lib/apt/lists entirely and start over. After removing /var/lib/apt/lists, `apt-get update` and subsequent operations perform as expected. I have a live example for you, I don't know if this reproducer requires certain mirror state or not. Attached to this bug is a copy of /var/lib/apt/lists, and if you populate your test system /var/lib/apt/lists with the contents of this tarball and configure the system to hit mirror is.archive.ubuntu.com for series plucky, you may see errors like this: Err:14 http://is.archive.ubuntu.com/ubuntu plucky/universe amd64 Packages 404 Not Found [IP: ... 3142] File has unexpected size (15764540 != 16133052).
