Bug sur l'installation de Mysql dans linux deploy 
If you use this command:
# apt-get install mysql-server
and can't complete the installation try this in the terminal:
# usermod -a -G aid_inet,aid_net_raw mysql
then repeat:
# apt-get install mysql-server
It worked for me. Debian jessie base on Asus P024.
