Not able to install Portainer after upgrade to 6.10.2

Running 6.10.2 on a ReadyNas 424.  After trying to install Portainer, the install fails and the ReadyNas admin login page appears.  Portainer is not installed.

I downloaded the logs via the web admin and saw this in the install_debpkg.log.

Any ideas on how to get this installed?
