Hey there, I moved my .kodi folder to get a clean slate. Realized today, that I can not install addons due to a malconfigured URL in /usr/share/kodi/addons/repository.xbmc.org/addon.xml, had to replace http://download.osmc.tv/kodi/addons/jarvis/krypton.xml.gz with http://download.osmc.tv/kodi/addons/krypton/addons.xml.gz and so on. Removed the Addons26.db and restarted the mediacenter service refreshed the addon database and I finally could install plugins again.
