Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 i18nspector : Depends: python3:any (>= 3.3.2-2~)
 libsikuli-script-java : Depends: jython but it is not going to be installed
 openjdk-7-jre : Depends: openjdk-7-jre-headless (= 7u75-2.5.4-1~deb7u1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Adding a pin for stable-updates to 990 and installing i18nspector from wheezy-backports solves it.
