Sure. But according to quote from your blog it’s not as dramatic as you’re saying:
There was a bug introduced in the September update that may prevent some systems from correctly receiving updates. If you are unable to update your system via My OSMC → Updates, then you should reboot, go to My OSMC → Updater → Manual Controls and select Scan for updates now.
I’ve followed these suggestions and it updated like a charm.
The image you installed is not the September update, you installed an unofficial build that was never published on the download page, so use at your own risk.
