Great that it worked out. The downgrade was trying to remove things
because libglib binaries need to be on the same version so it was
necessary to downgrade libglib2.0-bin/focal in addition to the main
library

Thanks! Soon after installing Ubuntu, I had disabled the updates (by
setting it to use only security updates, see attachment picture).
I did not know that changing that would change my system sources.
I changed it back to `All updates` and now I was able to install
`libglib2.0-dev`
```
$ sudo ap
> I did not changed my source repositories. Do I need to change
something on it?
well you did at some point,
ii libglib2.0-0:amd64 2.64.3-1~ubuntu20.04.1 amd64 GLib library of C
routines
that version isn't available in your sources, it comes from focal-
updates, so either you enabled the update
I do not have installed libglib2.0-dev as you can see
```
$ dpkg -l | grep glib2.0
ii libglib2.0-0:amd642.64.3-1~ubuntu20.04.1
amd64GLib library of C routines
ii libglib2.0-bin2.64.3-1~ubuntu20.04.1
> libglib2.0-dev : Depends: libglib2.0-0 (= 2.64.2-1~fakesync1) but
2.64.3-1~ubuntu20.04.1 is installed
it sounds like you installed libglib2.0-0 from focal-updates but don't
have that source enabled anymore?
