Mise à jour bloquée

Sur mon ordinateur portable, la mise à jour de la semaine du 9 au 15 décembre 2013 est resté bloquée.

calculate ~ #  emerge -uDN world

!!! Multiple package instances within a single package slot have been pulled 
!!! into the dependency graph, resulting in a slot conflict: 

media-libs/libgphoto2:0 

 (media-libs/libgphoto2-2.5.2-r1::gentoo, binary scheduled for merge) pulled in by 
   >=media-libs/libgphoto2-2.4.7:0/6= required by (gnome-base/gvfs-1.16.4::gentoo, binary scheduled for merge)

It may be possible to solve this problem by using package.mask to 
prevent one of those packages from being selected. However, it is also 
possible that conflicting dependencies exist such that they are 
impossible to satisfy simultaneously.  If such a conflict exists in 
the dependencies of two different packages, then those packages can 
not be installed simultaneously. You may want to try a larger value of 
the --backtrack option, such as --backtrack=30, in order to see if 
that will solve this conflict automatically. 

For more information, see MASKED PACKAGES section in the emerge man 
page or refer to the Gentoo Handbook. 

calculate ~ # 

Pour débloquer la mise à jour, avec l’aide du canal irc et de Flor_de_azucena, j’ai désinstallé les paquets

calculate ~ # emerge –ask –unmerge media-libs/libgphoto2 media-libs/flac virtual/libffi virtual/libiconv

J’ai fait la mise à jour

calculate ~ # emerge -uDN world

Après la mise à jour j’ai réinstallé les paquets

calculate ~ # emerge -a media-libs/libgphoto2 media-libs/flac virtual/libffi virtual/libiconv

Comme le kernel à changé

calculate ~ # module-rebuild -X rebuild

Puis un

calculate ~ # cl-setup-system

car les outils calculate ont été mis à jour, j’ai terminé par un

calculate ~ # revdep-rebuild
