Trouble installing via deb files

[malcolmbites]

Hello, I'm loving the new AnduinOS 2.0.1. Everything has been working smoothly except .deb files. I was able to install them in prior versions of AnduinOS, but every time I try to install one, I get the following error:

Error while installing package: old update-notifier-common package postinst maintainer script subprocess failed with exit status 1

I'm on AnduinOS 2.0.1; everything is updated; computer is a Dell Latitude 5490, though I'm not sure that makes much of a difference.

I apologize for not trying this first before coming here. I was updating my computer via the GNOME Software app. I went into the terminal and ran the usual update && upgrade and it showed an error. It also showed there were packages to remove with
sudo apt autoremove

So I ran that, which got rid of an old package that was causing problems. When I rebooted, the .deb packages that had supposedly failed to installed were all installed and ready to go. So, the problem has been solved.

Which package did you remove? This helps me making it better.

Here's what my history log shows:

Oh! I bet your machine might be from 1.3 upgraded right? libicu was a dirty package which it's version is in it's name.

I installed this in June -- so about 1.5 months ago. The latest Anduin was at 1.4.x at that time (based on Questing Quokka). I installed that, upgraded to 2.0.0 in early July, and then updated to 2.0.1 yesterday. I'm not sure where that libicu package came from, but you would know better than me. There weren't any difficulties with .deb files that I know of until the 2.0.1 upgrade.

Btw, thanks for all your hard work on this. You've made a beautiful OS!
