So recently I was trying to install an app which required newer version of libpango and tried installing it using
sudo dpkg -i libpango-1.0-0_1.50.4+ds-1_amd64.deb
Which gave me the following error
dpkg: dependency problems prevent configuration of libpango-1.0-0:amd64:
libpango-1.0-0:amd64 depends on libglib2.0-0 (>= 2.67.3); however:.
Version of libglib2.0-0:amd64 on system is 2.64.6-1 ~ubuntu20.04.4.
Then I tried doing something any logical person would do, install libglib using the same method which gave me the error
dpkg: error regarding libglib2.0-0_2.70.4-1_amd64.deb containing libglib2.0-0:amd64:
libglib2.0-0:amd64 breaks gnome-keyring (<< 40.0-3~)
dpkg: error processing archive libglib2.0-0_2.70.4-1_amd64.deb (--install):.
installing libglib2.0-0:amd64 would break gnome-keyring, and reconfiguration is not permitted (--auto-deconfigure might help)
Errors were encountered while processing:
libglib2.0-0_2.70.4-1amd64.deb
dependency of libglib which I tried installing from from apt (Big Mistake) which now shows apt unmet dependency the error is as follow:
sudo apt install scrcpy
Reading package lists... Done
Building dependency tree
Reading state information... Done
scrcpy is already the newest version (1.12.1+ds-1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
gir1.2-pango-1.0 : Depends: libpango-1.0-0 (= 1.44.7-2ubuntu4) but 1.50.4+ds-1 is to be installed
libpango-1.0-0 : Depends: libglib2.0-0 (>= 2.67.3) but 2.64.6-1~ubuntu20.04.4 is to be installed
libpangocairo-1.0-0 : Depends: libpango-1.0-0 (= 1.44.7-2ubuntu4) but 1.50.4+ds-1 is to be installed
libpangoft2-1.0-0 : Depends: libpango-1.0-0 (= 1.44.7-2ubuntu4) but 1.50.4+ds-1 is to be installed
libpangoxft-1.0-0 : Depends: libpango-1.0-0 (= 1.44.7-2ubuntu4) but 1.50.4+ds-1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
and when I input
sudo apt --fix-broken install
it goes completely crazy and asks to uninstall almost everything including GNOME desktop. Literally trying to nuke my complete system. Here is a list of all the programs it said to remove

Note: I tried installing libglib and follow the whole dependency thing manually but dpkg showed an error that updating libglib would break Gnome-keyring. Even If I could just clean that dependency error would be great!
Also I am extremely sorry, I think I wasn't supposed to install stable debian releases on its derivatives sorry about that. Good that I know about it but that might very well lead to requirement of a fresh install . I am using Ubuntu 20.04 LTS
