Remove APT cache (for Dockerfile)

Raw

remove_apt_cache

	apt-get clean autoclean
	apt-get autoremove --yes
	rm -rf /var/lib/{apt,dpkg,cache,log}/

Executing rm -rf /var/lib/{apt,dpkg,cache,log}/ will corrupt the apt environment and cause the following error:
Error: Could not open lock file /var/lib/dpkg/lock-frontend - open (2: No such file or directory)
Error: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?

Well yes, these commands should be the last RUN ditective given in the Dockerfile in order to reduce the size of it.

If you need to use apt from within the container later for any reason you can try rm -rf /var/lib/{apt,dpkg,cache,log}/* instead. This will keep the folders but remove their contents.
