Gotify: Missing Signature Key - Failed to install in the previous attempt

Rock-ons

Unable to install the Gotify docker image because the public key is missing or out of date. How do I update the install script to fix this issue? https://hub.docker.com/r/gotify/server

RockStor 3.9.2-57

Sounds like it’s caused an outdated Docker version. However, running yum update docker yields a repo error.

Hi @wwwizzarrdry!

The error you see is unfortunately related to the fact that you are using a legacy version of Rockstor; it was based on CentOS that is no longer supported by upstream, which also means that the docker version you have is also no longer supported.

We would strongly recommend you to consider upgrading your Rockstor installation to a recent one. I’m unfortunately very short on time at the moment for more details, but we do have a guide on our docs related to that very procedure:
https://rockstor.com/docs/howtos/centos_to_opensuse.html

Many others have done this migration here so I’m sure you’ll get all the answers you may seek.
