Fatal error when trying to enable demo mode

[gwalter]

Hello,

I just installed cPanel on a new VPS and I just noticed that I am unable to activate demo mode on any account.
cPanel 11.60.0.46, CentOS 6.9

I have setup thousands of servers before and have never seen such thing. there is no cpaneldemo on /etc/group. I am wondering if I add this group maybe demo mode would work ? But why is there no cpaneldemo group after installation ? Everything else looks fine...

I was able to enable demo mode on an user after manually creating the group 'cpaneldemo'.
But I still wonder what went wrong that this group wasn't created before or if I am breaking anything by manually creathing the group...

Hello,

Here's an example of the default entry for "cpaneldemo" in the /etc/group file:

# grep demo /etc/group
cpaneldemo:x:1002:

I'm unable to reproduce this issue on a test system. Can you verify if you see any error messages in /var/log/cpanel-install.log related to the /etc/group file?

Thank you.
