apt: held broke npackages

[deathkarr@…]

I'm trying to install zentyal onto a desktop edition of ubuntu 12.04 and a few selected modules fail to install.

Error

root command apt-get -qq --no-install-recommends --simulate install zentyal-zarafa zentyal-l7-protocols zentyal-ltsp zentyal-nut failed. 
Error output: E: Unable to correct problems, you have held broken packages.

Command output: . 
Exit value: 100

Hello dreathkarr,

this is normally a configuration error, not a bug. Go to the page ​​​​ http://trac.zentyal.org/wiki/Documentation/Community/FAQ/AptBrokenPackagesError for more information about this problem.

However in your case, since you have held broken packages you must use this command before doing any of the solutions of the previous link:

sudo apt-get clean

(This command cleans the downloaded packages cache)

Regards,
