I installed Oracle Java 7, only to realize there's a newer Java 8. So, I tried to remove Java 7 and then install Java 8, but I messed up somewhere along the way. I can't figure out how to fully remove or install either of them, and I'm getting error messages all over the place. Here's the errors when I try to run sudo apt-get purge oracle-java7/8-installer:
