I attach my /etc/squid-deb-proxy folder which might be relevant for the squid-deb-proxy team (although I didn't change these configuration files, it is just as it is after installing the squid-deb-proxy package).
In my opinion, the relevant part of the configuration is in: autogenerated/mirror-dstdomain.acl file containing lines: .archive.ubuntu.com security.ubuntu.com That in my opinion covers the lu.archive.ubuntu.com as well as security.ubuntu.com in my sources.list, and I still consider it as a problem in apt. Yet, thank you for looking into that. ** Attachment added: "squid-deb-proxy.zip" https://bugs.launchpad.net/ubuntu/+source/squid-deb-proxy/+bug/1952720/+attachment/5544349/+files/squid-deb-proxy.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1952720 Title: apt uses proxy in order to access local resources To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid-deb-proxy/+bug/1952720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
