SURVEY:AUTHOR1:BUILD_DIFFICULTY_COMMENT[string] The build notes indicate that the first build failed because "Ubuntu crashed".  It would have been useful to know more about this.  If this actually means that the host machine crashed, it suggests something may have been wrong with the host machine itself.
