RPi4 will only run Umbrel 1.3 , no updates possible, not even back to 1.5.0

My Rpi4 (8GB RAM, 2TB USB SSD) had been running 1.5.0 with just a Bitcoin node and ElectRS for months. During a vacation, it stopped working and would not reboot.

I checked the hardware by installing the latest Raspi-OS, and found no issues on the Raspi hardware, the SSD and the (new, fast u3) SD-Card. The following steps have all been repeated and verified with different SSDs and SDcards as well.

I tried many a times, starting with freshly cleared SSD and fresh written SDcard images, to get the Umbrel up from scratch again. Using 1.5.0 and any 1.7.x images repeatably failed when Umbrel booted up to the initial screen (where you set your password), and then never reacted to any http requests any more (LAN+WiFi), even after letting it settle for over a day. What could be happening there???

Out of sheer desparation, I finally tried an Umbrel 1.3.0 image on the SDcard - and this boots, configures, lets me install apps and then syncs my node - it’s been running for a good week now.

It shows 1.7.3 as available as an upgrade in the control panel, but when I try that it finishes the update, shows the welcome screen, and after password entry the http interface never reacts any more - just like the unsuccessful fresh installs did.

Does anybody have an idea what could be happening here? Or any hints on troubleshooting to get closer to the root cause?

no ideas? Am I the only one with this problem?

I tried updating my running 1.3.0-umbrel to 1.7.4 today, but ran into the same issue.

By the way, I can login by SSH while 1.7.4 (after the initial password dialog) is stuck showing “loading” in the browser. And umbreld shows 1.7.4 as it’s version. So if there is anything I could try on the command line, please le me know.

Side question: is there a documentation of terminal commands for 1.7.x anywhere? All I was able to find on the net are <=1.5.0 commands ( like /umbrel/scripts/xxx) which no longer work in 1.7
