Oh, right. Is that like when I couldn't access Trinity's repositories (for 
some reason, long time ago), and suddenly apt wanted to uninstall everything 
TDE? 

I've seen the && part of the command before, but mostly for getting keyrings, 
etc., and I prefer to do stuff one step at a time, if possible, to watch 
what's happening. However, I can (maybe) change.
