(Solved) - Update error after disabling CEC adapter

[supernano]

I disabled the CEC adapter via System -> Settings -> System -> Input Devices -> Peripherals, and since then I'm getting this error everytime I try to update via the xbian-config interface in Kodi:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libcec : Depends: python-libcec but it is not going to be installed

I can update via ssh with apt-get upgrade, although when I run apt-get update before, I get a warning:
W: Duplicate sources.list entry mirror://apt.xbian.org/mirror.txt/ stable/rpi-jessie armhf Packages (/var/lib/apt/lists/apt.xbian.org_mirror.txt_dists_stable_rpi-jessie_binary-armhf_Packages)
I'm not 100% sure that this warning is related to disabling the CEC adapter.

I'm running xbian on an old Raspberry Pi, and disabling the CEC adapter reduces load on the cpu and helps it run significantly smoother, so it would be great to not have to enable to fix this issue.

Please let me know if there's any further info or logs I can provide to help troubleshoot.

Thanks!
