UpdateNotifier Script - README


The UpdateNotifier script (Bash) can be executed by a cronjob and checks the actual version of a DietPi installation. If there is an update available, it will send an email notification to the user.


  • Install the software packages sendemail, libnet-ssleay-perl and libio-socket-ssl-perl.
  • You can use the command: apt-get install sendemail libnet-ssleay-perl libio-socket-ssl-perl
  • Copy the backup script to your computer.
  • Make the backup script executable: chmod +x
  • Edit the configuration part of the script.
  • Start the script from the command prompt: ./
  • Check if you get an email notification if an update is available.


This is a free tool and support is not included and guaranteed. Nevertheless I will try to answer all your questions if possible. So write to my email address biegel[at] if you have a question :-)
