I get the following error when I use the bash one liner script for setup for scrollphat

These aren’t normal Raspbian apt sources, what OS are you running? Or have you manually added these “pipplware” sources?

i am on retropie 4.2. I have not added pipplware sources. where do i find these?

Honestly, it’s only via the good graces of Google that I’ve any idea what pipplware is. It looks like RetroPie supply a Kodi installer that relies upon their sources. It could be either their sources, or your internet connection, that are at fault. Have you tried running the installer again since?

I have tried running the installer serveral times. Unfortunately I get the same error. I understand retropie is an experimental OS for scrollphat

Well in this case, the OS’s package management is fundamentally broken by a bad package source. There’s not much we can really do about that automagically.

You may have to dig around in /etc/apt/sources.list or /etc/apt/sources.list.d to find and disable this source.
