IceBear Afaik the official LE repo is not populated for RK yet.
I have ADDON_SERVER_URL overwritten in my ~/.libreelec/.options
otherwise it will default to LE repo.
I rebuilt LibreELEC from your master branch and changed
In file http://LibreELEC.tv/distributions/LibreELEC/options
ADDON_SERVER_URL="http://raybuntu.libreelec.tv/addons/"
My packages/mediacenter/kodi/config/repository.rbrepo/addon.xml file also shows
<addon id="repository.rbrepo"
name="RB Add-ons"
version="9.0.6"
provider-name="Raybuntu">
<extension point="xbmc.addon.repository"
name="RB Add-ons">
<info>http://raybuntu.libreelec.tv/addons//9.0.6/RK3328/arm/addons.xml.gz</info>
<checksum>http://raybuntu.libreelec.tv/addons//9.0.6/RK3328/arm/addons.xml.gz.md5</checksum>
<datadir zip="true">http://raybuntu.libreelec.tv/addons//9.0.6/RK3328/arm</datadir>
</extension>
But I still can't connect to RB Add-ons repo.
Tried compiling RK3328 z28 and trn9.
I can only open this link with a double '9.0.6' on a web browser - Index of /addons/9.0.6/9.0.6/RK3328/arm/
Any further help?
