[TriLUG] Ubuntu 18.04 upgrade problem

[Pete Soper via TriLUG]

Thanks for the cookbook, Bill. Unfortunately, that isn't what I'm 
looking for. I'm talking about a single  package update screwing up over 
and over because the left hand thinks a file is locally available while 
the right hand discovers it isn't there. I'm looking for a way to move 
the state of the system backwards a step so it is as if the need for 
that package upgrade has just been discovered and there is the chance to 
get the needed files properly from the 'Net. I think I could simply 
remove the package, but it might cascade badly, all the way to forcing 
reinstalls of a very large cross-dev tool chain, etc, so I'm looking for 
a surgical solution.
