A reboot may be necessary -- this is how I bypassed the issue. I also found that killing dovecot's instances would not end the stop/start threads, and had to kill them also. Killing the stop thread allowed installation to proceed until dovecot was started again (which would hang); killing this start allowed the update to finish successfully. And then, just in case, I rebooted.
