I can’t replicate in a container. Maybe make sure that `apache2` is installed and those directories exist then try again? `apache2` should create that directory, so it’s not clear why it wouldn’t exist.

The directories exist and apache2 is installed:  
/etc/apache2/sites-available$ ls  
000-default.conf default-ssl.conf  
$ pwd  
/etc/apache2/sites-available  
$ which apache2  
/usr/sbin/apache2

Not sure what else to try?

Try bouncing apache2 and see what comes out of `journalctl`. We run the ood\_portal\_generator on bounces so it’ll run.

Otherwise you may try running it manually.

```auto
/opt/ood/ood-portal-generator/sbin/update_ood_portal
# or
/opt/ood/ood-portal-generator/sbin/update_ood_portal --force

```

bouncing apache2 didnt work but running $/opt/ood/ood-portal-generator/sbin/update\_ood\_portal created the file. Now when I go to the page I am greeted with a login page with an internal server error after entering my login information:

You can look in `/var/log/apache2/` for apache errors.

I cannot replicate from a fresh install. From other posts I’m seeing you’re building from the source and now you’re installing a `.deb`?

I’m not quite sure what’s wrong with your system, but my guess is is that the 2 installs are incompatible and are messing each other up.

 ![image](https://us1.discourse-cdn.com/flex015/uploads/osc/original/2X/a/aefe17ed1a4af1138b77694eed09d090c17525e4.png)

I’d suggest you reset that machine back to it’s original state and start all over with a `.deb` file - not building from source.
