introduction
Le script ci-dessous utilise une interrogation déclenchée par interruption pour des messages spécifiques de dbus, et chaque fois qu'il voit une demande d'arrêt / redémarrage, il testera si un gestionnaire de packages tel que dpkgou aptest en cours d'exécution. S'ils sont en cours d'exécution, la demande d'arrêt sera annulée.
Installer
Puisque vous avez mentionné que votre ami ne veut pas toucher la ligne de commande, vous devrez soit ssh dans sa machine, soit venir l'installer manuellement.
Configuration manuelle
mkdir $HOME/bin- Copiez la source du script, enregistrez-la dans un fichier nommé
preventShutdown.sh
- Le script doit être exécutable. Utilisez
chmod +x $HOME/bin/preventShutdown.shpour le faire
- Ajoutez un script à la liste des routines à exécuter lors de la connexion à Unity / Gnome à l'aide de l'application Applications de démarrage ou en plaçant manuellement un
.desktopfichier dans$HOME/.config/autostart
Configuration alternative
sudo apt-get install git
cd /opt
sudo git clone https://github.com/SergKolo/sergrep.git
sudo chmod +x /opt/sergrep/*
Ajoutez le script en tant qu'application de démarrage.

# Basic idea : This runs dbus-monitor which waits for
# "RebootRequested" memberf from com.canonical.Unity.Session ,
# which apprears only when the user clicks the shutdown option
# from the Unity's top right drop down box. Why RebootRequested ?
# Because this message is guaranteed to pop up once user presses
# the shutdown button.
# The while loop with read command does the big job.
# dbus-monitor sends initial message , so we want to filter only
# The output that contains the string we need, hence the case...esac
# structure employed here. Once we get the proper message.
# we check whether update-manager or package managers are running
# If there is one instance, then call CancelAction method
# and send notification to the user.
# Both dbus-monitor and while loop run continuously. This
# can be launcher as script in `/etc/rc.local` or `/etc/rc2.d`
# or preferably (!) in `/etc/xdg/autostart/` .
# Here is sample /etc/xdg/autostart/preventShutdown.desktop file
#
# [Desktop Entry]
# Type=Application
# Name=Prevent-Update
# Exec=/home/$USER/bin/preventShutdown.sh
# OnlyShowIn=GNOME;Unity;
# Terminal=false
#
# Remember to make this file as well as script be root-owned with
# chmod +x /path/to/Script.
# It is preferred to store the script in user's personal $HOME/bin
# folder.
# Make sure to edit $HOME/.profile file to include that into $PATH
# variable
