==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
iRM 0.9.8 - iRedMail version (check /etc/iredmail-release):
Ubuntu 18.04 - Linux/BSD distribution name and version:
MySQL - Store mail accounts in which backend (LDAP/MySQL/PGSQL):
NGINX - Web server (Apache or Nginx):
No - Manage mail accounts with iRedAdmin-Pro?
Internal server error - [IMPORTANT] Related original log or error message is required if you're experiencing an issue.

Internal server error - That's the error/log I get after running sudo apt update/upgrade
I just got this in the access.log:

192.168.0.23 - - [06/Dec/2018:13:41:39 -0700] "GET /iredadmin HTTP/1.1" 500 32 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36"

which is probably not helpful

I had to comment out the apt entry for SOGo in order to update
If I load mail.mailsite.com directly I do get an error in nginx/error.log about listing directory contents
Have I completely hosed my iredadmin?  or have you seen this before and have a fix?
Thank you!
