[SOLVED] Install Problem when i change the vu2000

[hahaha]

I never use default setup in my servers for security reasons, and so, when i change the default user of vu2000 to uv2000 and install isp-cp then i have the follow error.

Setting GUI Permissions: ................................................................................​..........................................................
................................................................................​..........................................................
................................................................................​..........................................................
................................................................................​..........................................................
................................................................................​..........................................................
................................................................................​..................................................done
Setting Engine Permissions: .chown: `root:vu2000': invalid group
...........done

And if i try to start apache2

Starting web server (apache2)...apache2: bad user name vu2000
failed!
invoke-rc.d: initscript apache2, action "start" failed.

So i change the user in sites-available/00_master.conf to uv2000 and apache2 works perfect.

But i dont know about the permission i have to change.

I use Debian Etch with a fresh install.

Sorry my bad english.

Thanks you guys for this great job.
