I've made recently a mistake on my BPI pro with my OS jessie: domoticz showed an update green icon to update ...and I've unfortunately clicked on this icon....result was Domoticz doesn't start anymore...of course i've made no back-up

Anyway I've reinstalled OS Jessie (took me 2 days...) on my BPI and now I can't install domoticz:
I try to install domoticz with:
curl -L install.domoticz.com \ sudo bash
then I have:
GnuTLS: A TLS fatal alert has been received
Unable to establish SSL connection
See joined image...
Can somebody help my to re install domoticz?
Thanks a lot!
