Unmet dependencies upon installing libvirt* and virt-manager after distribution upgrade

I have been doing an upgrade from Ubuntu 18 to 20.04, then 20.10. Now, I need to install virt-manager, which I'm sure has a package supported on Ubuntu 20.10. When I try to install it using sudo apt-get install virt-manager, I get unmet dependencies problems stating that packages cannot be installed.

The following information may help to resolve the situation:

The following packages have unmet dependencies.
 libvirt-glib-1.0-0 : Depends: libvirt0 (>= 1.2.8~rc2) but it is not installable
 python3-libvirt : Depends: libvirt0 (>= 6.0.0-0ubuntu5) but it is not installable
                   Recommends: libvirt-daemon but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

My guess is that I have old package making conflicts with those, but that would not make sense due to displayed error messages.

I did try sudo apt-get update, and this did not change anything.

Trying to install dependencies brings down to this :

E: Package 'libvirt0' has no installation candidate

Here is the /etc/apt/resource.list :

deb http://archive.ubuntu.com/ubuntu/ groovy main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ groovy main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ groovy-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ groovy-updates main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ groovy-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ groovy-security main restricted universe multiverse

deb http://archive.ubuntu.com/ubuntu/ groovy-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ groovy-backports main restricted universe multiverse

deb http://archive.canonical.com/ubuntu groovy partner
deb-src http://archive.canonical.com/ubuntu groovy partner

I do not know why some packages cannot be installed while I should be able to install them. Does anyone faced this issue already? Am I missing something?

Also, I could not find any related question around here mentioning this kind of stuff happening after a distribution upgrade; although I am aware that unmet dependencies questions are many.

Downloading libvirt0 deb package from ubuntu's website and installing it made it work, but it is clear that there is still a problem in packages list.

Sadly, Ubuntu 20.10 is end of life as of today - you should consider upgrading to 21.04 or back to 20.04

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.
