I clicked "Continue the partial update" ; Now I have lots of packages to install and I don't want to

Due to a supposed problem in my Ubuntu 18's packages, I could not upgrade to Ubuntu 20. Instead of checking what was going wrong with all the packages problems, I solved one or two packages problems (I think) and then, even if some problems were still present (I think), I wanted to start the upgrade to Ubuntu 20 (big mistake...!).

The graphical upgrader (or CLI, I don't remember) told me that I was going to do a Partial Upgrade. I clicked on "Continue". Then, I stopped it.

I'm still on Ubuntu 18. So the partial upgrade isn't done I think.

Now when I type: sudo apt-get update/upgrade/dist-upgrade, I get:

The following packages were automatically installed and are no longer required:

(lots of packages)

The following packages will be REMOVED:

(lots of packages)

The following NEW packages will be installed:

(lots of packages)

The following packages will be upgraded:

(lots of packages)

2009 upgraded, 377 newly installed, 104 to remove and 0 not upgraded.

I think all these packages are related to my Partial Upgrade. However I want to cancel my Partial Upgrade. In other words, I don't want to see all these packages. What should I do?

What I've already tried

sudo rm /var/lib/apt/lists/* but it didn't work...

package-management updates upgrade apt 18.04

  1. The file /etc/apt/sources.list was rewritten by the upgrader (Ubuntu 18.04.5 word bionic was replaced by focal, for Ubuntu 20). I have edited this file in order to replace focal by bionic. Then I've typed sudo apt-get update. Now the problem is solved. When I type sudo apt-get update ; apt-get upgrade ; apt-get dist-upgrade it works well: I have no package listed!

    NB: I looked in /etc/apt/sources.list.d, all the files contain bionic so I didn't have to replace anything here.
