Hi,
We’ve recently started utilizing zip packages since the added support from octopus. For security reasons we cannot send packages directly from our CI server to Octopus. We instead have to use our 3rd party package manager which is Nexus. I know you currently have support to have feeds using nexus with nuget packages, but would it also work if it were zips?
Hi,
Thanks for reaching out. Unfortunately It won’t work. .zip files are only supported if you push them to the Octopus built-in repository.
If this is a feature you would really love us to support, please feel free to add it to our uservoice. We are always looking for feedback from the community in order to organize our priorities
