Hi Mark,

You might have to run "sudo apt full-upgrade". But, specifically, the calf 
problem might be caused by the calf-ladspa package, which may also have to be 
completely removed ("sudo apt purge calf-ladspa && sudo apt full-upgrade"). 
So, if the full-upgrade doesn't clean things up the first time, removing the 
calf-ladspa package and running the upgrade again should do the trick.

I CC'd this into the Ubuntu Studio Users list since there are others that 
might benefit from this. Feel free to subscribe to it at https://
