I try to update openehab but I when I type apt-get update I get
Err https://dl.bintray.com stable/main armhf Packages
server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
W: Failed to fetch https://dl.bintray.com/openhab/apt-repo2/dists/stable/main/binary-armhf/Packages server certificate verification failed. CAfile: /etc/ssl/certs/ca-certif
When I type
wget -qO - ‘https://bintray.com/user/downloadSubjectPublicKey?username=openhab’ | sudo apt-key add -
gpg: no valid OpenPGP data found_.
Any Idea ??
