I wrote a test application. It works on Windows, but it doesn't work on Ubuntu Server 12.04 x86. I installed vibe.d from https://code.google.com/p/d-apt/wiki/APT_Repository
I got warnings such as "Failed to listen something" then I try to run my test application:

alex@alexserver:~/projects/vibetest$ vibe
[B7267F80:00000000 INF] Updating application in '/home/alex/projects/vibetest'

I tried to use different ports but it doesn't help me. Why it doesn't work?
