Dovecot listener doesnt start after 3.2.8 upgrade

I did the 3.2.8 upgrade on my master server and everything was fine.
Went to install 3.2.8 on my mail server and after the install imap wasnt working. When I restarted Dovecot, the listeners would not start. I looked at the /etc/dovecot folder and it renamed my old configuration file to dovecot.conf~ and the new dovecot.conf file didnt have all the stuff in in it compared to the old file. So I renamed the new config file to dovecot.conf.new and renamed the old file back to dovecot.conf and then restarted the service and things came up.
So my question is, am I missing something on the server since I jumped from 3.2.2 to 3.2.8 to cause the dovecot not to work or is there something else going on?

Thanks.

 

This is running on Ubuntu 18.04.06 LTS

Yep, there was nothing else in it. That's what seemed odd and strange to me. That's why I renamed the old back to the original and things came right up.

 

I'll be updating to 3.2.8p1 shortly so I'll see if it does it again and let you know.

Thanks.
