"Error determining host id" and license file not found when installing Zend Platform
Today, after reinstalling Ubuntu Dapper from scratch on my laptop and losing a significant ammount of hair due to frustration, I finally managed to install Zend Platform and I'm posting the solution here in case someone else faces the same problem.
At a certain point in the instalation, I was getting an error message saying "Error determining host id" and later on another one showed up saying that the license file couls not be found.
After much fiddling with lots of stuff in my system, I finally thought that it could have something to do with the path I was installing it from. The directory where I was installing it from was called "zend platform", with a white space, which was the source of the problem.
I renamed the directory to "zp" and it installed without a problem.
So there you go, I hope this saves you some time and frustration.
