We have a Nexpose Virtual Appliance (VMware) and needed to upgrade the Ubuntu OS to the latest supported release 20.04. We did the step upgrade from 16.04 to 18.04 LTS just fine and verified the console and services worked, but after doing the upgrade from 18.04 to 20.04, the console hangs on 22%: Initializing datastore.
If you’re still experiencing this issue I would recommend opening a support case for assistance.
Some troubleshooting steps I might suggest thought would be to bounce the VM again. Just simply reboot the whole the VM and see if the console starts this time. If it does not you can look through the nsc.log to see what exact steps it’s taking, if there’s any errors in the log, etc.
If something got corrupted you could always reinstall if you had a local backup to pull from. You would simply copy out your latest backup to a separate directory and then uninstall/reinstall the security console with the latest installer and try again.
