Comment 1 for bug 2013334

Thank you for the bug report. I created a PPA based on the upstream information you provided, located here: https://launchpad.net/~lvoytek/+archive/ubuntu/haproxy-fix-bad-request-responses

It is based on the commits:

https://github.com/haproxy/haproxy/commit/3f5fbe940733bba84b5ee875af5b13aa3144aa41
https://github.com/haproxy/haproxy/commit/658f971621839f3b928da099dfe3092b47cbc958
https://github.com/haproxy/haproxy/commit/ca7218aaf073627b665459bd881b2b35a481602a

If you would like to test it with 22.04 you can run:

sudo add-apt-repository ppa:lvoytek/haproxy-fix-bad-request-responses
sudo apt update
sudo apt upgrade

This should affect kinetic too, but the fix has been added to lunar. I'll mark the bug info as such
