Hallo everybody,
I am a absolute newbee on Linux and Lamp. I got the LAMP system up and running on Linux Mint 18. The server (lokalhost) works just fine with the testsite. Now I tried to install Openproject and got this:

Installation looks fine for me:

karsten@karsten-desktop ~ $ sudo apt-get install openproject
[sudo] Passwort für karsten:

Es müssen noch 0 B von 157 MB an Archiven heruntergeladen werden.
Nach dieser Operation werden 470 MB Plattenplatz zusätzlich benutzt.
Vormals nicht ausgewähltes Paket openproject wird gewählt.

The openproject package provides an installer. Please run the following command to finish the installation:
sudo openproject configure

Configuration does not look that good:

karsten@karsten-desktop ~ $ sudo openproject configure

If I do the “web start” I get this error:

As espected the system is not running, so if I do “127.0.0.1/openproject/” I get:
Not Found
The requested URL /openproject/ was not found on this server.
Apache/2.4.18 (Ubuntu) Server at 127.0.0.1 Port 80

What am I doing wrong?

Thank very much for your help
