today on logging in to my laptop (Lenovo Thinkpad T460s),I noticed a little red kind of "⛔️" icon in the top bar of my screen, I am using Ubuntu 20.04 64-bit by the way, anyway when I clicked into it, it told me that I had a certain package called libgl1-mesa-dri:i386 that needed to be reinstalled but there is no archive for it, and that it usually means that my installed packages have unmet dependencies. Now from doing further research I found out this package is related to Steam Installer and when I found out I attempted to remove Steam Installer, but then at the top it said, "Unable to remove "Steam Installer": Removing not available." For further information on what the "error" message looked like, I have attached an image below. Error Message

I have ran apt-cache policy libgl1-mesa-dri:i386 and the output

libgl1-mesa-dri:

You miss the focal-updates and/or focal-security repository pockets.

Open Software & Updates (software-properties-gtk) and enable these components back by visiting Updates tab and setting For other packages, subscribe to to All Updates.

Then updates using

sudo apt-get update
sudo apt-get instal -f
sudo dpkg --configure -a
sudo apt-get dist-upgrade
