So for the solution...

I did not completely follow the right way to get to a proper result.

The way I did it was simply installing a few of the twitter tarbals debs via touching them and the rest via inception.

While this might even have been okay, it's necessary to unlock the system packages before. We're going to fix this.

First you need to get root.


Run apt-get -f install

It will ask you to remove mp-harmattan-001-pr

Do so. It only removes the metapackage, not the actual dependencies it has.

Only then you can fully purge twitter.

apt-get purge twitter

Once finished do

apt-get install mp-harmattan-001-pr

It will install the old twitter again.

Now you'll need N9 QuickTweak. Pick the latest version from the appropriate thread and use tweak QQ

You'll have to follow the fitting route for your device and it'll be dead obvious what to do.

Select the correct entry (in this case 001) and then option 1 to unlock system packages.

Once done, close N9 QuickTweak and untar the tarbal containing the new twitter debs into a folder, that'll only contain the tarbals contents.

Open a terminal, gain root, cd into the tarbals extracted folder, and use inception on all packages

/usr/sbin/incept *

If I'm not mistaken.

It will install the new Twitter again but this time, the metapackage won't moan ;-)

Thanks for mergin the threads @thedead1440

Cheers and good luck!
