According to RFC 2616 "The Host field value MUST represent the naming authority of the origin server or gateway given by the original URL." The current implementation causes problems with some proxy vendors. This commit fixes this.  - https://salsa.debian.org/apt- team/apt/commit/86d4d98060f36c7e71c34af20a1193a75496ef72#54d3193c5d10a0032c80c3a6d3f069507265547f [Test Case] Here's one reproducer an impacted user brought to my attention: # /etc/environment http_proxy="http://internal:8080" https_proxy="http://interal:8080" To support application development activities in-house, I had to configure Azure CLI APT repository following the instructions from "https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-apt?view =azure-cli-latest": $ sudo apt-get update $ sudo apt-get install curl apt-transport-https lsb-release gnupg $ curl -sL https://packages.microsoft.com/keys/microsoft.asc | \ $ gpg --dearmor | \ $ sudo tee /etc/apt/trusted.gpg.d/microsoft.asc.gpg > /dev/null $ AZ_REPO=$(lsb_release -cs) $ echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $ $ AZ_REPO main" | \ $ sudo tee /etc/apt/sources.list.d/azure-cli.list $ sudo apt update In the final "apt update" command, APT respects system-wide network proxy variables and successfully fetched Canonical repository data over HTTP. However, it was unable to fetch the newly added Microsoft packages repository served via HTTPS. By using Wireshark to examine the HTTPS request made by APT, the request body reveals as: CONNECT packages.microsoft.com:443 HTTP/1.1\r\n Host: internal:8080\r\n User-Agent: Debian APT-HTTP/1.3 (1.6.11)\r\n ... ... There also is an automated test case in the package that runs as part of autopkgtest that tests a scenario like this, see the commit. [Regression Potential] * Fix already in debian, and Eoan * Has been reviewed/approved by juliank * A test package (pre-sru) has been provided to an impacted user, and he confirms it solves the situation.
