I updated my subscription since Nov 20, but unable to upgrade

@alexmesfin Unfortunately v4 is not yet available as a release - it is still in RC (Release Candidate) phase, and only available by building your own installer:

Rockstor 4 Installer Recipe - call for beta testers

I am somewhat relieved, and a little surprised, to finally be announcing our new installer recipe. And I would like to call on those interested to ‘check our workings’. We do not yet have a binary download of the resulting installer as we must first ensure we are finalised on what it is we intend to be distributing in binary form in the first place. This new repository release, and this forum threads/request, is all part of that process. So please visit the above repo and try out the instruct…

However, v4 is based on a different underlying Linux distribution (OpenSUSE LEAP instead of CentOS for v3) so would, I assume, require a full re-install. I believe your current version to be the last one of the v3 lineage.

EDIT: Also, your Stable subscription will apply to v4, and is easy to transfer using the online Rockstor Appman tool if necessary.

I’ve been running v4 for a few months now without any issue after I took the plunge and built the installer image using the instructions linked above.
