Hey David, Just wondering if you have seen the apt related docs at: https://help.ubuntu.com/community/AptGet/Howto/#Setting_up_apt-get_to_use_a_http-proxy

They connect to an AWS OpenVPN VPN and use a Squid 3.5 AWS hosted Proxy. They work fine. We have tried upgrading one to 20.04. Same setup. From the command line curl or wget can happily download an Ubuntu package from the Ubuntu Mirror site we use. But "apt update" gets lots of "IGN:" timeouts and errors. The package we test curl with is https://mirror.aarnet.edu.au/ubuntu/pool/main/c/curl/curl_7.68.0-1ubuntu2.5_amd64.deb The Squid log shows a line the doesn't occur for the successful 18.04 "apt updates": 1625190959.233 81 10.0.11.191 TAG_NONE/200 0 CONNECT http://mirror.aarnet.edu.au:443 - HIER_DIRECT/2001:388:30bc:cafe::beef - The full output of an attempt to update is: Ign:1 https://mirror.aarnet.edu.au/ubuntu focal InRelease Ign:2 https://mirror.aarnet.edu.au/ubuntu focal-updates InRelease Ign:3 https://mirror.aarnet.edu.au/ubuntu focal-backports InRelease Ign:4 https://mirror.aarnet.edu.au/ubuntu focal-security InRelease Err:5 https://mirror.aarnet.edu.au/ubuntu focal Release Could not wait for server fd - select (11: Resource temporarily unavailable) [IP: 10.0.11.82 3128] Err:6 https://mirror.aarnet.edu.au/ubuntu focal-updates Release Could not wait for server fd - select (11: Resource temporarily unavailable) [IP: 10.0.11.82 3128] Err:7 https://mirror.aarnet.edu.au/ubuntu focal-backports Release Could not wait for server fd - select (11: Resource temporarily unavailable) [IP: 10.0.11.82 3128] Err:8 https://mirror.aarnet.edu.au/ubuntu focal-security Release Could not wait for server fd - select (11: Resource temporarily unavailable) [IP: 10.0.1.26 3128] Reading package lists...

While running, the line 0% [Connecting to HTTP proxy (http://vpn-proxy-d68aca8a8f7f81d6.elb.ap-southeast-2.amazonaws.com:3128)] appears often and hang for a while. I've tried upping the squid logging and allowing all, but they didn't offer any additional information about the issue. Any advice would be greatly appreciated.
