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 Hit:1 http://archive.ubuntu.com/ubuntu eoan InRelease Hit:2 http://archive.ubuntu.com/ubuntu eoan-updates InRelease Hit:3 http://archive.ubuntu.com/ubuntu eoan-backports InRelease Hit:4 http://security.ubuntu.com/ubuntu eoan-security InRelease Reading package lists... Done Building dependency tree Reading state information... Done 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. For upgrade information, please visit: http://www.ubuntu.com/releaseendoflife Get:1 Upgrade tool signature [1 554 B] Get:2 Upgrade tool [1 342 kB] Fetched 1 343 kB in 0s (0 B/s) authenticate 'focal.tar.gz' against 'focal.tar.gz.gpg' 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: ``` ==> /var/log/squid-deb-proxy/access.log <== 1595069772.862 212 192.168.3.47 TCP_MISS/200 3349 CONNECT changelogs.ubuntu.com:443 - HIER_DIRECT/91.189.95.15 - 1595069774.726 2 192.168.3.47 TCP_MEM_HIT/200 1950 GET http://archive.ubuntu.com/ubuntu/dists/focal-updates/main/dist-upgrader-all/current/focal.tar.gz.gpg - HIER_NONE/- application/x-gzip 1595069775.410 681 192.168.3.47 TCP_HIT/200 1342082 GET http://archive.ubuntu.com/ubuntu/dists/focal-updates/main/dist-upgrader-all/current/focal.tar.gz - HIER_NONE/- application/x-gzip ``` 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.
