when I am trying to push my commits to the mercurial repository, I get the error message “ssh abort: no suitable response from remote hg!”. This is fixed when I edit my local “/etc/ssh/ssh_conf” and remove the line “SendEnv LANG LC_*”.
I am using Ubuntu 16.04 LTS and hg 5.3.2, the server is running Kallithea 0.5.2 on Debian Buster.
The server's “/etc/ssh/sshd_config” contains the line “AcceptEnv LANG LC_*”. Therefore my guess is that Kallithea is responsible for sending the error message.
