Installation error

I am getting a 404 attempting to download/install the software. Is this a known issue and, if so, when will it be back in service?

This should be working now, there was a DNS error earlier but was resolved around 1PM (CDT).

If you still have problems try:

sudo bash -c "$(wget -O - http://ubuntu.bluecherrydvr.com/scripts/install)"

Thank you for the update!

Should I be using a specific version of Ubuntu Server?

We build and test with 16.04 and 18.04, both are LTS releases, so one of those.
