subprocess errors during 11.1 install

I am trying a clean install of 11.1 on a Dell desktop computer with a blank hd. I went with the default install except that I added the lamp/web server option because I want to try and install Openbiblio from the education repository. I have been getting these subprocess errors that I can ignore/abort/retry. Whats going on here? It is being installed from a dvd image that I downloaded. Thanks

Did you run the media check from the dvd boot menu??
