Can't upgrade from 13.10 to 14.04

[Vv]

Here is the error message (in french) :

Impossible d'évaluer la mise à niveau

Un problème insoluble est survenu lors de la préparation de la mise à
niveau.

Ceci peut-être dû à :
* la mise à niveau vers une version de développement d'Ubuntu ;
* la version de développement d'Ubuntu est actuellement utilisée ;
* des paquets logiciels non officiels, non fournis par Ubuntu.

Si rien de tout cela ne s'applique, veuillez signaler ce bogue en
utilisant la commande 'ubuntu-bug ubuntu-release-upgrader-core' dans
un terminal.

Restauration du système dans son état d'origine

Thx for your help!

Hi Brian,

thanks for your answer, but I don't understand why the upgrade process considers some packages are in a "keep this version" state.

When I check in Synaptic, I don't see any package in such a state...

Any idea?

Cheers,

Vivien

Status changed to 'Confirmed' because the bug affects multiple users.

Hello,

I have reviewed bugs similar to this one on launchpad: it usually caused by additional ppas (like xorg-edgers-ppa in bug 1309484).

This doesn't apply in my case.

When I review the logs, it seems ubuntu-desktop version is frozen, but this must be done during the upgrade process, since it doesn't appear in such a state when I open synaptic. I don't know how to solve this.

Is there a way to diagnose the bug more precisely?

Any help would be greatly appreciated.

I just found that Bug #1322306 seems related to this one.

If anyone has an idea on how to solve this, I'm still stuck.

Sigo teniendo el problema para actualizar a 14.04...

No se ha podido calcular la actualización
Ha ocurrido un problema mientras se calculaba la actualización
Eso pudo ser causado por:
Actualizar a una versión de ubuntu aún no publicada
Estar ejecutando la versión actual, aún no publicada, de ubuntu
Paquetes no oficiales de software no proporcionados por ubuntu

Alguien que me pueda dar una solución???

Hello,

I still haven't found a solution to this problem. I was hoping that an update of the release upgrader package would fix the problem, but this didn't happen. And now Ubuntu tells me 13.10 is not supported anymore...

Is there any alternative to a fresh reinstall?

Thx,

VV
