@Soph.jpg I would recommend against updating the OS without immediately also updating FOG to the latest stable afterwards.
I intensely test 9 different Linux distributions daily against the latest fog installer code & the latest patches for said distros for quality control - this is an automated process. I am fairly confident that FOG or OS updates specifically will not break the installation process for the master branch of FOG - because we will catch it in the lower-tier branches. Of course something environment specific could break it for you though - and then you’d be down until you figured that out.
Scripting the automatic updating and installation of fog is not complex, it’s a couple of lines.
cd to the correct git directory,
git checkout master;git pull;cd bin;./installfog.sh -y and you’re off to the races. If you want to get fancy, it’s very easy to setup this so that you can get a success/failure message on Slack when these things happen.
