InvoiceNinja Installer-Updater script

I used to get the script from one of toms videos but can’t find it now and googlefu is failing me haha where did this go we have been paying for the hosted solution to support the project but v4 got buggie so decided to migrate to v5 but now its by far worse so we can’t afford this disruption to our business so looking to self host our invoiceninja but can’t find that script anymore.

Here is the old V4 update script
