Lehet kezdeni valamit ezzel a hibával Ubuntu rendszerben?

Found the solution, but thought I would leave it up here for all the users that are going to need it.

Open a new Terminal window and run the following command:

sudo gedit /etc/apt/sources.list.d/google-chrome.list

In the text file that opens edit the file so that the line reads:

deb [arch=amd64] [link] stable main

The only addition you need to make is entering the [amd64] architecture after ‘deb’ but preceding the ‘http’. Do not edit or replace any other text in this file.

Hit Save. Close the Gedit window.

Now return to the Terminal and refresh your package list by running:

sudo apt-get update

The ‘failed to fetch’ APT error should no longer appear.
