XenServer v6 installation problem: UNSUPPORTED_INSTALL_METHOD - other-config:install-repository was not set to an appropriate value, and this is required for the selected distribution type

It has been a long time since I played with the XenServer for the last time.

I managed to install the XenServer without any problems. The XenConsole installation went flawlessly as well. But when I tried to create a new VS using the provided templates i run into the desribing problem:

What I did in XenCentre:

1. XenCentre
2. New VM
3. Ubuntu Lucid Lynx 10.04(32 bit) 
4. Then use the default settings and once you see the screen with the:

"Select the installation method for the operating system software you want to install on the new VM"

You seen on the screen a page where you should select the desired installation source. In my example the option for "Install from ISO library or DVD drive" was grey but you can still select one of the ISO images from your storage pool (if you defined it previously).

Problem:
If you attempt to run the VS to start the installation you will get an error like this:

UNSUPPORTED_INSTALL_METHOD - other-config:install-repository was not set to an appropriate value, and this is required for the selected distribution type

There is not much on the Citrix support/technical knowledge page for this. The solution is here although.

Solution:

• To create VM and start the installation from a ISO file saved on the attached storage (NFS or CIFS) you have to use the correct profile: Other install media
• To use the Ubuntu Lucid Lynx 10.04(32 bit) profile you have to specify an URL for the data to be retrived (for example like http://mirror.clarkson.edu/ubuntu/ )
