Hi!

-1st:-
Today, all my GPG keys for authentication are lost and I cannot
import the "trusted.gpg" key because import the key is not possible.

Restore defaults of keys is not possible. I click "Restore Defaults" and
nothing is happen.

How can i restore default keys of Ubuntu Mate 20.04 LTS?

I cannot use Synaptic and Update-Manager anymore because the keys are gone.

-2nd:-
What does this mean and how can I repair it?
/usr/bin/apt-key: 59: rm: not found

Please help, thanks!

I re-installed apt packages
and copy my backuped old gpg keys into "/etc/apt/trusted.gpg.d"

then:
sudo apt update

Now, all is repaired and my keys are available @ Synaptic Repo... authentication section.
