I recently upgraded from wheezy to jessie. During the installation Mathematica was removed. Trying to reinstall it via sudo apt-get install wolfram-engine produces the error 

The following packages have unmet dependencies:
 wolfram-engine : Depends: libharfbuzz0a (>= 0.9.19-1co2rpi2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages

I have tried to install libharfbuzz0a (from both jessie and wheezy) but also get an error:

The following packages have unmet dependencies:
 librsvg2-2 : Depends: libpangocairo-1.0-0 (>= 1.36.0) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

How can I stop going down this rabbit hole and get Mathematica working again

I have asked the same question on mathematica.stackexchange.com and user ilian posted a very useful answer. Basically it is possible to install the latest Wolfram deb package wolfram-engine_10.0.2+2015020304_armhf.deb with dpkg and then fix an entry in /var/lib/dpkg/status. Please refer to the exact details to ilian's post.

Credits are due to him alone, upvote his answer there! :-)

  • I tried that solution, but when I do sudo apt-get -f install I get this error: "The package wolfram-engine needs to be reinstalled, but I can't find an archive for it." – Arne Aug 17 '15 at 16:17
  • Never mind, I got it now, the dpkg process got interrupted... – Arne Aug 17 '15 at 16:47

    Now that the "official" Raspbian based on Jessie is out, I can confirm that it comes with Mathematica. Still Version 10.0.0 as with Wheezy. – András Aszódi Oct 09 '15 at 11:06

In the short term I'm not sure you can.

jessie is the current experimental build and you must expect broken packages every now and then.

You could approach the Raspbian maintainers and ask them when a fix is expected. The answer may be "it'll be fixed when it's fixed".

Debian runs with three package distributions.

  • stable: current code name wheezy
  • experimental: current code name jessie
  • testing: always called sid

Stick to stable if you want stability.
