This seems to be the root of it:

Investigating (0) libjpeg-turbo8-dev [ amd64 ] < none -> 1.1.90+svn733-0ubuntu4 > ( libdevel )
Broken libjpeg-turbo8-dev:amd64 Conflicts on libjpeg62-dev [ amd64 ] < 6b-15ubuntu1 -> 6b1-2ubuntu1 > ( libdevel )
  Considering libjpeg62-dev:amd64 0 as a solution to libjpeg-turbo8-dev:amd64 -1
  Holding Back libjpeg-turbo8-dev:amd64 rather than change libjpeg62-dev:amd64

Broken r-base-dev:amd64 Depends on libjpeg-dev [ amd64 ] < none > ( none )
  Considering libjpeg62-dev:amd64 235 as a solution to r-base-dev:amd64 37
  Removing r-base-dev:amd64 rather than change libjpeg-dev:amd64

I. e. we have packages that previously depended on libjpeg62-dev in oneiric/lucid, but now the upgrade pulls in libjpeg-turbo8-dev which Conflicts: libjpeg62-dev.

We could perhaps drop the Conflicts, or make it versioned, or add a Provides: libjpeg62-dev?

Fix uploaded, we now build a real libjpeg-dev package to aid apt over the upgrade.

This bug was fixed in the package libjpeg8-empty - 8c-2ubuntu7

---------------
libjpeg8-empty (8c-2ubuntu7) precise; urgency=low

  * Build a real libjpeg-dev package, to fix upgrades from lucid/oneiric.
    Without this, apt rather holds back libjpeg62-dev instead of installing
    libjpeg-turbo8-dev. (LP: #940179)

I guess the current fix could be the reason I can't install the Robot Operating System (www.ros.org) binary packages for "oneiric" on Precise.

ROS package libopencv2.3 needs libjpeg62-dev and libtiff4-dev needs libjpeg8-dev, which needs libjpeg-turbo8-dev, which is conflicting libjpeg62-dev.

These three packages seem to be the only reason why it doesn't install the binary packages.

I opened a new Bug #1070168 that could be related because I have the same warning :

Les paquets suivants contiennent des dépendances non satisfaites :
 libjpeg-turbo8-dev : Est en conflit avec: libjpeg62-dev mais 6b1-2ubuntu2 devra être installé
E: Erreur, pkgProblemResolver::Resolve a généré des ruptures, ce qui a pu être causé par les paquets devant être gardés en l'état.
