Suddenly sudo apt update is not working anymore on my Ubuntu 18.04.6 machine.
I get the following error:

I have tried changing the repository mirror to no luck. I tried running sudo apt update from within an Ubuntu docker image and the same error comes out. Would this mean that this is a network issue? Or I can still do/check something?
Thanks!
