The problem seems to be with Jenkins: the version you installed is incompatible with java 1.7.0_131. Every time you use apt-get to install another package, it complains that jenkins installation is broken.

I am going to assume you are running a linux distribution like Ubuntu 14.04. If this is the case, you should be able to fix the issue by doing the following:

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk

Then you need to change the default version of java with:

update-java-alternatives --list
sudo update-java-alternatives --set /path/to/java-8

For example:

sudo update-java-alternatives --set /usr/lib/jvm/java-1.8.0-openjdk-amd64

Now you can run:

sudo apt-get upgrade

Now jenkins should upgrade/install correctly. After this, apt should work again without errors/complaints.
