Is this still a planned feature? If not, we'll probably expedite our transition to VSTS.
We have recently made good progress on getting Tentacle running on Linux via netcore and expect it to be available in the next couple months. https://github.com/OctopusDeploy/Issues/issues/3596
As for Octopus Server on Linux, we have also started working on this effort however the current focus is for internal use for running Hosted Octopus. There are some additional complications that come with running Octopus on Linux particularly in the context of “run on the server” and s a result I wouldn’t expect a version of this to be available until mid-year at the earliest.
Most of our other additional tooling and libraries like Calamari are now available to be run on netcore and run on Linux.
