It is supported, at least in the git version. But I'm not sure if your shadowsocks installation is correct. You know that shadowsocks-libev is in the Ubuntu repository and you just need to type sudo apt install shadowsocks-libev? Not the latest version, but 3.0.0 you mentioned is even older. Remove the other versions and specify /usr/bin/sslocal to run.

3.0.0 is an old python version from 2018 (there is also an old shadowsocks-qt5 version 3.0.0, also 2018). Now shadowsocks-libev is more actual. And shadowsocks-rust is even more. Although, I see that libsodium is needed to support chacha20.

Thank you for your reply, it is indeed because of the version problem, this problem has been solved now
