I switched my repository source from "main" to "best mirror" and got the same error message.

My internet connection is working normally.

Question 1:
Is this related to the "BIND"-problem?

See:
https://www.ubuntu.com/usn/usn-3346-1/

Question 2:
How do we fix it? :confused:

Hello @alpinejohn

This error recently appeared here also when updating the system.
I went to check on the boutique software and refers to accessibility tools, the latest updates (ORCA) I believe.

When you open here in the browser, you are unavailable as you click on the boutique software.

In the browser:

404 Not Found
The requested URL /accessibility-dev/ppa/ubuntu/dists/xenial/main/source/Sources was not found on this server.

and

Lost something?

This page does not exist, or you may not have permission to see it.

If you have been to this page before, it is possible it has been removed.

The solution I found was temporarily disabling PPA in programs and upgrades. That went well the updates.

For the unavailability of the PPA I do not believe that it is related to “BIND”.

You can manage third party repositories from Software & Updates (under System → Administration). If you remove software from the Boutique, it will remove its PPA/source too, if applicable.

Some suggestions:

Hallo Swart

Thanks for the reminder that ppa 's can be the source of these woes. :slight_smile:

The offending ppa 's have been identified by a process of trial and error. They were:

(A)
ppa.launchpad.net/ffdiaporamateam/stable/ubuntu xenial main

(B)
ppa.launchpad.net/accessibility-dev/ppa/ubuntu xenial main

I removed them and the update process run properly once again. :slight_smile:
