I tried this, and at first couldn't figure out why the packages were in 
a broken state that wouldn't install.  Then I realized I had added the 
repo for focal (20.04) but I'm still on bionic (18.04).  Now the 
packages are good to go for getting dovecot upgraded and problems 
resolved before I do the OS upgrade.  I have gone through the notes on 
the wiki for upgrading from 2.2 to 2.3 and only found a very small 
number of things that needed updating.

I'm going to start doing upgrades in about an hour.

Thanks,
Shawn
