I have been trying to get openmanage installed on linux debian stretch

I have attempted to add the repository and get errors

I have tried adding many iterations of the following (I am not naming the repository or component correctly most likely)

https://linux.dell.com/repo/community/openmanage/910/stretch/dists/ stretch

 

Based on this page I have added the key (even though it might be an incorrect one)

https://linux.dell.com/repo/community/debian/

 

That is only the first part of the problem, since I decided to try and add it insecure since I really need the raid tools currently, and long term I would like to conquer this.

Attempting to install with

apt-get install srvadmin -all

claims srvadmin-all doesnt exist, must each component need to be done one at a time?

 

Could anyone give me the proper repository syntax, as well as the correct key to install if I have that wrong, and then the install syntax.
