ssh in focal with xiaomi mi a2

josevidal

I can't connect via ssh from a Xiaomi A2 with focal. I have the historical BQE4.5 krillin (with xenial) for years working with ssh but I can't get it with the Xiaomi A2.
is SSH working on focal?
where can I look for information to fix it?

Thanks.

SSH works fine, I don't know if it helps ... try disabling usb-moded-ssh service, on my device is disabled.
