[X2Go-User] Warning message about a Xubuntu dist-upgrade

["BOTZ Franck (Administrateur Systèmes et Réseaux) - DDT 67/SIDSIC/Pôle Infra"]

Hi !!

So, i have a curious issue with a system update.

I've done a snapshot from my X2Go server wich work on a Xubuntu 14.04 64 
bits system at 24/09/2015. Everyting works great on it : Firefox, 
Thunderbird, Qgis, Libreoffice.

Friday 02/10/2015 i've done a dist-upgrade on Xubuntu. A new kernel (65) 
comes.

After that, I've got a i/o error on Firefox, Thunderbird, and Qgis 
opened but menus don't work. Libreoffice seems to be good.

When I restore the snapshot, no problem appear.

So next step is to identify the origin of this issue.

When I launch an apt-get upgrade, the problems appear again.

List apt-get upgrade -s :

I see 3 things
   * a new kernel
   * a new version of x2goagent
   * a new version of nx-x11-common

Any idea ?

Regards
