UCS update errors

I am running UCS 4.4-2 and am having problems updating. The server is erroring out because the web server configuration files have changed. Yea, no kidding they’ve changed … how do I update to a newer version and put my web settings back into place?!

The error message I get if I try to apply 4.4-3 … tail -f /var/log/univention/updater.log

WARNING: There are modified Apache configuration files in /etc/univention/templates/files/etc/apache2/sites-available/.
Please restore the original configuration files before upgrading and apply the manual changes again after the upgrade succeeded.
This check can be skipped by setting the UCR variable update44/ignore_apache_template_checks to yes.
Error: Update aborted by pre-update script of release 4.4-3

Obviously I don’t have the original config files.

How do I set the UCR variable?!

The original file should be https://github.com/univention/univention-corporate-server/blob/4.4-4/services/univention-apache/conffiles/etc/apache2/sites-available/000-default.d/00start

Looking at the folder structure its probably smarter to add additional files (e.g. 01mymodifications) instead of changing the original files.

ucr set update44/ignore_apache_template_checks=yes

Yea - I altered the original file because I could not get the system to stop overwriting my needed config changes any other way.

Good input for future, but it would take a fair amount of effort to find all of the changes and undo them. The info you provided allowed me to get the system up on 4.4.x – thank you.
