Hello all,

I have Ubuntu 20, I did snap install bitcoin-core, now I want c-lightning, but can't see to make it work.  I can add the PPA for lightning network, install it; but it can't find bitcoin. 
  Do I need to reinstall bitcoin in a different way than snap? I would like to preserve my blockchain and bitcoin.conf (yes I have a backup of that)

Does anyone have a tutorial I can follow?
