Martin Kosek 185ca8f6fc Install tools crash when password prompt is interrupted
When getpass.getpass() function is interrupted via CTRL+D, EOFError
exception is thrown. Most of the install tools are not prepared for
this event and crash with this exception. Make sure that it is
handled properly and nice error message is printed.
