Fix Umbrel Background Services

If you aren't able to run OTA updates, you can do the following to resolve the situation:

Umbrel OS (Raspberry Pi)

If you're running the normal Umbrel OS install on a Raspberry Pi you can run this in a terminal on a computer connected to the same network as your Umbrel:

ssh -t umbrel@umbrel.local "mkdir -p umbrel/logs && sudo systemctl restart umbrel-startup"

Fix OTA updates on custom Umbrel installs

⚠️ Important: You only need to follow these instructions if you have a custom Umbrel install. If you're running Umbrel OS on a Raspberry Pi you can safely ignore this.

Custom Umbrel OS installs that started Umbrel with sudo scripts/start in an SSH sessions and then closed the SSH session encountered a bug where the OTA update script would not work due to missing file descriptors.

This has now been fixed (getumbrel/umbrel#269), however the update process for existing users involves manual steps.

ffmpeg compress

Re-encodes an input file as an MP4 with a constant rate factor of 24

ffmpeg -i input.mov -crf 24 output.mp4

Lower crf value means higher quality and larger file size. 24 gives reasonable results with good compression.
