SBC apt upgrade 3cxsbc -t testing response: "invalid"

[steve_HR]

While trying to upgrade the 3CX SBC apt responds that the -t parameter of "testing" is invalid. I attempted to upgrade again after a reboot of the SBC and had the same response. Here is a transcript.

You don't have the testing repo listed. See this post:
