> From what I understand: "sudo apt-get clean" will finish with a state zero (0), if this finish with a state <> than zero, and if the check is true it will generate an exception, @potiuk, we don't want that exception to happen, right? for that reason we are changing "check=False" Actually if it will finish with state != 0. By default "exit 0" in POSIX systems (standard for UNIX/LINUX - like systems) means that it was "success". Any non-zero value means "failure". That's why "command || true" is used to always succeed. The command "true" always returns "0" and "command || true" works in the way that regardless what is returned by command, always "true" result will be used. -- This is an automated message from the Apache Git Service.
