is the startup script supposed to take over 30 minutes to run the startup script. – "processing triggers for man-db" taking pretty pretty long time for the lab
If you are running a small vm (like an f1-micro), it will take a long time. You can ssh into the VM and run
ps aux | grep mandb to see if it is still running.
You can also remove "apt-get -yq upgrade" from the startup script to speed things up
