apt - Ubuntu 13.10: Upgrade interrupted because of openjdk-7

I was running an apt-get upgrade (not version upgrade, just normal), when I got this message:

You might want to run 'apt-get -f install' to correct these.

The following packages have unmet dependencies:
icedtea-7-jre-jamvm : Depends: openjdk-7-jre-headless (=
7u51-2.4.4-0ubuntu0.13.10.1)

openjdk-7-jre : Depends: openjdk-7-jre-headless (=
7u51-2.4.4-0ubuntu0.13.10.1)

openjdk-7-jre-lib : Breaks: openjdk-7-jre-headless (< 7u45-2.4.3-1)

E: Unmet dependencies. Try using -f.

I then run as recommended "apt-get install -f" and here is the output:

How can I fix this error?
Thanks

UPDATE:

The 1st time, I ran the command, there was no output. Now, running it again, I get:
