Hi there,

I still want to know whats going in. I still get the segfault, now trying 2.1.9
On another machine, which is the same ubuntu version, it is working.

The core does not say really much. Can I do something else?

Thx
Kai

I'm getting pretty similar segfault running this on Mint Rosa 17.3 which is basically the same ubuntu 14.04.

i installed droidmote now on my test ubuntu 16.04 64 bit and it work without problems.

try change port and password and make sure you don't have problems on netwok interfaces.
