We have added Debian 10 (codename Buster) to our supported distributions. Our distribution images and netboot installers are available from the management console of any Prgmr.com VPS.
Customers who want a fresh install of Buster onto an existing VPS using PV virtualization should contact support. You can determine if your VPS uses HVM or PV virtualization by logging into the management console and selecting “system details”. Here’s a link to Debian bug #932416 which contains more information.
