As you can see, some errors pop up. This is the first time they're happening.
They seem to be related with Groovy Gorilla update repositories? I don't know, not an expert, that's why i'm posting here.

Are these problems to be concerned with, like they might break the system? Are they server side or do I have to fix them?

Here are the system's specs, if they may be of any help:

Operating System: Kubuntu 20.10
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0
Qt Version: 5.14.2
Kernel Version: 5.8.0-43-generic
OS Type: 64-bit
Processors: 4 ? Intel Core i5-7200U CPU @ 2.50GHz
Memory: 7,7 GiB of RAM
Graphics Processor: Mesa Intel HD Graphics 620

Thank you very much!

Seems a probable cause, or there is a problem with your country's mirror servers.
You can wait and see if they fix it, or you can change the mirror used


Change your repos from the Brazil mirrors to the 'worldwide' ones: Open Discover, and go to Settings, then Software Sources.

Change 'Download from' to "main server'

Perfect, it worked.
Thank you very much!

Should I just let the Main Server as the default mirror from now on?

You can with no problem but your local mirror may be faster once it is working properly.
