We’re moving out of Cloudsmith as continuing to host the package there would be too costly for us.
We’re very thankful for the service and help CloudSmith provided, and would recommend their product for smaller open-source apps and private packages anytime!
At the moment we don’t have the bandwidth (pun intended) to set up an alternative repository but might be moving to self-hosted (probably CloudFlare) in the upcoming weeks.
So sorry for the inconvenience and thank you for your patience.
Note that you can always get a .deb and .rpm package in the release section of the GitHub repository.
