I did a new install and tried to upgrade to V18 but couldn’t. I did the edit to /etc/apt/sources.list
deb Index of /osmc/osmc/download/dev/gmc-18 gmc-18 main
but apt-get dist-upgrade said
rbp2-mediacenter-osmc is already the newest version (17.8-244).
I am trying to set up the amazon vod with DRM and need V18. but no plugins were installed yet.
