Well, if you need more info, you'd need to install Ubuntu 6.10.
It happened to me on 2 of my PC's, running Ubuntu Linux.
At first, there was no effect, since after the message everything was installed correctly, but now nothing installs.
There are a lot of posts relating this problem around the Web. The thing is, that most posters didn't check the Error Console, so they didn't write about the InstallLocation message.
Let;s hope it will get solved soon.
