Thank you. I did not imagine this would happen. It is the first time, in
my life, that I am upgrading Debian this way.

Mmm... so, I should also 'apt upgrade' with Debian 9 (Stretch)
sources.list? This is different from many directions I found in the web.

I want to upgrade to Debian 10 (as a step to Debian 11), but I am having
trouble with some signature. Let me show a full description. In my first
try, I was not with an updated Debian 9. Someone asked me that, and then
I tried to repeat everything after updating things. So, I

1. Restored sources.list to be what Debian 9 stretch uses

2. Asked 'synaptic' to reload the package database

3. Tried to do 'apt update' as root, but it does not work. GPG signature
error.
