Whenever I install any software/package, I get the following result. The software does get installed and works correctly but does this is not the supposed output. What is wrong with my system?

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service acpid restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop acpid ; start acpid. The restart(8) utility is also available.
acpid stop/waiting

Errors were encountered while processing:

This occurs even while installing from the Software Center:

And there is an error while sudo apt-get update about the unity-tweak-tool also.

Note: This error has become long after trying to install Qt Creator, earlier it was only about four-five lines and now its this long.
