Can not install apps

I installed the Umbrel Node on Rasberry Pi 4, and the blockchains are synced. The Bitcoin Core and Lightning are running well. But I can not install app. I tried several times and rebooted the device, but still failed. Here is the error log.

How to solve this?

Re-flash your mSD card with latest Umbrel version. Then try again adding new apps.
