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
$ 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/184.108.40.206 - 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.
- 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.
