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

All packages are up to date.
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
Your Ubuntu release is not supported anymore.

Authentication failed
Authenticating the upgrade failed. There may be a problem with the network or with the server.
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.
Notes:
- For possible close-voters: the same happening when I try to upgrade 18.04 LTS to 20.04 LTS with
sudo do-release-upgrade -d
. - I have reported bug 1888058 to launchpad.
- Removing
squid-deb-proxy-client
deb-package and specifying proxy byAcquire::http::Proxy "http://192.168.12.34:8000";
in/etc/apt/apt.conf
does not change anything.
squid-deb-proxy-client
. HavingAcquire::http::Proxy "http://192.168.12.34:8000";
in/etc/apt/apt.conf
does not change anything.
