Why were libraries deleted during autoremove?

Question

linux

Hey!

I recently played with zsh in Ubuntu 20.04
As I played around, I decided to clean everything through autoremove and, for some reason, two libraries were demolished for me, which, as far as I understand, are not directly related to zsh (libfwupdplugin1 and libmessaging).

I would like to understand the reason, tk. I really don't want to demolish an important lib in such games :) I 'm attaching the

output from /var/log/apt/history.log.

Answer 1

Most likely shurshur and res2001 from the comments to the question are right.

Answer 2

Playing with autoremove, for me, is not a smart idea!
Do you even know what this command means?
This is an automatic deletion, if anything)
