I've installed Alfresco Labs a few times, but I've never run into this:
download Alfresco-Labs-3Stable-Linux-x86-Install into my tmp dir.
as root … chmod a+x
and then ./Alfresco-Labs-3Stable-Linux-x86-Install
and nothing happens… no error message or anything else. It just goes back to the prompt. I've tied changing ownership to root, but it doesn't make any difference. I can't find anything in the log.
I assume I'm missing some libraries or something other prerequisite, but I don't know what it would be.
