Keeping your package manager happy in Ubuntu and Debian -- from prior upgrade discussion

I'm coming late to this discussion; sorry about that. Re: "old packages from a previous upgrade" ... in Ubuntu, the "do-release-upgrade" script is supposed to clear those out. But if do-release-upgrade crashes out, people can get lost as they don't know how to duke it out with the package manager. My standard "update the software" in Ubuntu/Debian looks for deletable and orphan packages specifically. Nuking orphan stuff and removing old cruft beforehand, is THE WAY to make your upgrades work better. The only other source of complication is old additional software repos in /etc/apt/sources.list.d/[...] which are NOT supported in the OS release you're upgrading INTO. Does your package manager want you to delete stuff? dpkg -l | grep '^r' | awk '{print $2}' | sort | fmt ... this command should return no output if your system is clean. Does your machine harbor software not attached to any software repo? (these are AKA "Obsolete packages") Learn the shocking truth: aptitude show '~o' | grep Package | awk '{print $2}' | sort | fmt ... this command should also produce no output on a happy machine, other than perhaps one-shot .deb files installed from downloads (i.e., if you download the zoom client by hand and install that without using a repo, etc). The more cruft, the worse your major-version-upgrade experience will be. The upgrade is performed entirely by the package manager, so that part of your OS needs to be happy before you can start an upgrade with confidence. --MCV.

This is terrible news! Have they closed already? I was planning to go there on Tuesday (July 2) when I have a medical appt. in Newton. They were probably destroyed by the Web, BUT their location was not ideal. The traffic in that area was horrible.

I suspect that you have an old package from a previous upgrade, did you come from Ubuntu 16.x or earlier on this same system? You might try to run the following, all as root or with sudo: apt clean apt update apt install --fix-missing apt upgrade and see what each command says. So please share the full and complete outputs. You might also be able to do: apt purge linux-image-extra-4.4.0-212-generic But maybe you can share the output of: dpkg-query -l | grep linux-image-extra and see if that package is listed and share with us the full details? From the looks of it, you DID do a previous upgrade from Ubuntu 16.0 at some point, but didn't didn't do: apt autoremove once you finished the ugprade to 18.x, but I think we can make this work with a bit of finagling. Also, please look at these instructions, and once we get this fixed, I'm going to suggest you go right to 22.04 LTS, and then just stick with LTS versions if you can't upgrade very often. https://help.ubuntu.com/community/EOLUpgrades But the last thing to try, if none of the above works might be to do: dpkg --purge --force-remove-reinstreq linux-image-extra-4.4.0-212-generic and see if _that_ does the trick.

Yeah, let's fix your apt-repo, which seems to be in a wierd state. But maybe you can also post what your hardware is, including the output of: lspci > Some of what I read on the Web mentions tex files that could cause > Number 1. I do have TeXstudio installed.

Do you have any special stuff in /etc/apt/sources.list or do you have any extra file in ls /etc/apt/sources.list.d/ and what I'd probably do is remove all extra sources in there for now, just to make sure things are ok.
