Hi! This bug report was originally about buster and in my opinion a backport is necessary (stretch also had one). I reckon mostly servers use Let's Encrypt, and they mostly run Debian buster/stable. Given that upstream doesn't seem to change to that much, is that a possibility?
I didn't reopen this bug report and will leave that to the maintainer's discretion, however, I did want to mention this. Kind regards, Paul -- Web: http://paul.luon.net/ | E-mail: p...@luon.net Matrix: @paul:luon.net | GnuPG: 0xC6DE073EDA9EEC4D
