Trying to install the Ubuntu 15.04 64 bit version 1.9 release on Ubuntu 15.04, getting this error:
Dependency is not satisfiable: libavcodec54 (>=6:9.1-1)|libavcodec-extra-54(>=6:9.18)Do you have the universe/restricted/multiverse components enabled in the Ubuntu package manager settings?
Oh sorry, the Ubuntu naming got me confused, it appears I was trying a 14.04 version SDK on 15.04.
Uninstalled and reinstalled 14.04 and currently running the Panda3D installer.
