Bug Description
I'm running `squid-deb-proxy` server in my local network. It works well for all package downloads while running all APT commands. It is configured for all possible known URLs of the mirrors including *old-releases*. The Ubuntu 19.10 client has installed client side - the `squid-
```
$ dpkg -l squid-deb-

But when I try to start upgrade process to get 20.04 LTS - using `sudo do-release-upgrade` in the terminal I got the following error message:
```
$ sudo do-release-upgrade

I do not see anything special in the logs on `squid-deb-proxy` server side:

How should I fix the problem with *Authentication failed* to run the upgrade through proxy server normally? I do not want to switch proxy server (or exclude its configuration from the client) off to fix the problem.

The results does not depend on proxy configuration method - the "Authentication failed" message is shown for both `squid-
Note: previous versions do not suffer from this bug. I have successfully upgraded 16.04 LTS to 18.04 LTS with enabled proxy. But the upgrade from 18.04 LTS to 19.10 and from 18.04 LTS to 20.04 LTS is now impossible because of the "Authentication failed" message.
