Just to be clear, we’re not currently aware of any general issues with updating Roon Bridge, and the most recent release was Core only (no mobile updates, no updates for Roon Bridge), so there was no update last week.
My understanding is that there was an issue with updating on DietPi, and Dan is on it. In the world of software, it’s doesn’t get a lot better than “the bug is fixed in our current beta and will go live with the next release”, so I think you just need to be patient on this one.
Also note that there have been very few changes in Roon Bridge over the last few months, if any.
