Public bug reported:

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-deb-proxy-client` package.

```
$ dpkg -l squid-deb-proxy-client | tail -n1
ii  squid-deb-proxy-client 0.8.14+nmu2  all          automatic proxy discovery 
for APT based on Avahi

$ sudo apt update

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 
Checking for a new Ubuntu release

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-deb-proxy-
client` avahi-based package and for `Acquire::http::Proxy` in
`apt.conf`.

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.
