Let’s try to manually update an app…
After you login via SSH (you can see steps here Official Umbrel Troubleshooting Guide and FAQ under How to SSH into Umbrel on Rasperry Pi), then let’s try to manually update an app, we can troubleshoot by first attempting the Tailscale app, or replace its name with another applicable one if you’d like if you don’t have Tailscale… using this command:
sudo ~/umbrel/scripts/app update tailscale
Alternatively, you can also install an app as well with this command:
sudo ~/umbrel/scripts/app install tailscale
You can see the correct names of the apps to use in this command where they are listed here: https://github.com/getumbrel/umbrel-apps
After attempting the manual update or install please let me know if it hangs on any errors or if you experience any issues here. If it gets stuck on a downloading line here it will show you a percentage if it is indeed progressing. If it is slow can I confirm if you are connected via Wi-Fi or ethernet, and what is the results of an internet speedtest? (https://www.speedtest.net/) Also, out of curiosity can you share RAM and Storage Usage from settings?
Also, I’m happy to review your debug log- please share this via going to System > Troubleshoot > Start
Usually, restarting via System > Restart again and then just waiting a few extra minutes resolves this issue and the updates should become available- otherwise, happy to further troubleshoot!
