If you run 
sudo apt update
or
sudo apt upgrade
it will break nginx - the web server that provides the control panel and VitXi.
The fix is to uninstall and reinstall nginx:

Then reinstall Vital PBX as per the install instruction:
Installing VitalPBX 4.5 In Debian: Easy How-To Guide
All settings and data is retained.
Keep in mind that removing NGINX will remove all the VitalPBX packages including add-ons. So, I don’t know how safe is this!
Yes it did remove add ons but I just reinstalled them. I did not find anything else broken.
Why do you say the update breaks nginx? I haven’t seen it happen on my 4.5 systems.
I just ran sudo apt update and sudo apt upgrade - nginx threw an error - stopped and would not restart. PBX was still working but without the ability to monitor or control it. I don’t know why it happened but it may happen to someone else.
We had no issue with update.
Could be due to OS and other resources.
Updated 3 system with following command, with no issue:
sudo apt clean all
sudo apt update
sudo apt upgrade -y
I saw another post in forum of a user with a similar nginx issue, might have been some issue with the people that update first. @miguel was there some sort of nginx bug that was fixed?
Run the command below before updating the system.
sed -i 's|include /etc/nginx/pbx-addons/\*;|include /etc/nginx/pbx-addons/*.conf;|' /etc/nginx/sites-enabled/vitalpbx
@miguel Is this needed to be run on a pariticular version or why the need to run the command?
Before updating to 4.5.1, to avoid issues if the NGINX package gets updated during the system update.
Probably should PIN this or push another update that fixes this since more then one person has now run into the issue and I have an unstable system that no one seems to know a fix to.
This must be manually done when running a full update of the O.S!
What is now and in the future the best way to update a PBX without issues?
Thanks
This update is the fix for future updates!
Yes but it doesn’t help with what it broke! This should be pinned and the subject changed as a better warning to others. I didn’t find this until after it broke my system!
Run the command below via the command line
dpkg --configure -a
Finally, reinstall the Logger Core package
apt-get --reinstall install logger-core -y
This and restart NGINX again was the fix! Thanks!
