APT
It is necessary to execute the following commands as root once, to use apt-get as you like:
> apt-get -y update >/dev/null 2>&1 > mv /sbin/init /sbin/init.old > touch /sbin/init > chmod 755 /sbin/init > dpkg --configure libc6 >/dev/null 2>&1 > mv /sbin/init.old /sbin/init
Installing an application by using the PackageManager will set up APT automatically.
