Voilà, QElectroTech devrait désormais être installé. Vous pouvez le lancer via la commande “qelectrotech”.
Pour le peu que votre environnement de bureau respecte les standards FreeDesktop.org, QET devrait également apparaître dans ses menus et les fichiers .qet et .elmt devraient s'ouvrir par défaut dans QElectroTech.

L'entrée suivante affecte une priorité haute à toutes les versions du paquet QElectroTech dont le numéro de version commence par 0.100. :

laurent@debian:~$ cat /etc/apt/preferences.d/40qelectrotech-devel
Package: qelectrotech*
Pin: version 0.100.*
Pin-Priority: 1001

As root

# echo -e 'Package: qelectrotech* \nPin: version 0.100.* \nPin-Priority: 1001' > /etc/apt/preferences.d/40qelectrotech-devel

With sudo

echo -e 'Package: qelectrotech* \nPin: version 0.100.* \nPin-Priority: 1001' | sudo tee /etc/apt/preferences.d/40qelectrotech-devel > /dev/null

sudo apt-key export 1D4FB6C1 | sudo gpg --dearmour -o /usr/share/keyrings/qelectrotech.gpg
echo "deb [signed-by=/usr/share/keyrings/qelectrotech.gpg] https://debian.qelectrotech.org/qet/builds/debian/ unstable main" | sudo tee /etc/apt/sources.list.d/qelectrotech.list

Now remove in /etc/apt/sources.list :

 deb https://debian.qelectrotech.org/qet/builds/debian/ unstable main
