For the moment the Rasp is off, I was so desesperate that I put it back in its frame.
If I remember well, I had multiples errors in my tries, like language not compatible (was in french though ... sorry), autogen.sh not found, condensate-qt error 1 ... I know it's not really precise, I know the world of linux for that. But I must admit that it gets on my nerves. I tried everything described in many different sites without any success.
I think that the armhf system is not suited to support even the linux/ubuntu/debian client.
Others Rasp client were not working.
I might try again ... later ... when I'll be cooled
(Sorry for the mistakes ... a french is speaking)
No problem, take your time
I will try too with a raspberry pi later.
