'su: user postgres does not exist' during install

[fangman]

Hello,

I'm trying to run the install of alfresco-community-4.2.e-installer-linux-x64.bin on CentOS release 6.4.

The installation always fails with the error:

Installing

Error: There has been an error.
su: user postgres does not exist
Press [Enter] to continue :

This is a new server install.  There is no existing postgres user on the system.  Any suggestions on the issue, or potential workaround?

The user account with which you are trying to install does it have root level access?

[fangman]

Thanks for the response.  Yes, I was running as root.  The only thing I can think of is the system authenticates against AD.

[mitpatoliya]

No I do not think so as installed out of box does not go for it.

Maybe you don't have enough RAM allocated? I have the same OS and haven't had any issues. Vanilla install on root.

4GB of Ram and starting out with 4CPU's.
