Very good, fantastic!
Re-insalled using the existing installfog.sh - did its thing (checked packages, database scheme etc.)
cd /root/fogproject/bin
./installfog.sh
WOL and postdriver scripts seem to be working again!
Thanks! I shall run this command below so it doesn’t happen again until I am prepared to get Ubuntu updates.
apt-get -y remove unattended-upgrades
