I have been been running trusty since the first alpha release, pulling daily updates. I also installed the oracle-java7-installer from the WebUpd8 PPA. Today I noticed during a dist-upgrade that oracle-java7-installer was being removed. On my edge system I just allow all the defaults so I allowed the removal expecting to try out the java 8 version anyway. However when I went to install the oracle-java8-installer package it wanted to remove "apt"!? This obviously sparked my concern, as it even feels like a security concern. Help understanding this would be greatly appreciated.
$ sudo apt-get install oracle-java8-installer
