Run UBOS on Beagle Bone BlackΒΆ

You can run UBOS on your Beagle Bone Black by downloading an image, writing it to a micro SD card, and booting your Beagle Bone Black with that card. (Alternatively you can keep running your existing Linux distro on your Beagle Bone Black, and run UBOS in a Linux container. This is described here.)

  1. Download a UBOS boot image from Beta images for the Beagle Bone Black are at Look for a file named ubos_yellow-bbb_LATEST.img.xz.

  2. Optionally, you may now verify that your image downloaded correctly by following the instructions at Verify your downloaded UBOS image.

  3. Uncompress the downloaded file. This depends on your operating system, but might be as easy as double-clicking it, or executing

    > xz -d ubos_yellow-bbb_LATEST.img.xz

    on the command line.

  4. Write this image file “raw” to a micro-SD card. This operation depends on your operating system:

  5. On first boot, it is recommended you have a monitor and keyboard connected to your Beagle Bone Black. If this is impractical, create a UBOS staff so you can securely log in over the network without the need for monitor or keyboard.

  6. Remove the micro-SD card and insert it into your Beagle Bone Black. If you created a UBOS staff, insert the staff into the USB port. Then, plug in the Beagle Bone Black’s USB power.

  7. When the boot process is finished, log in as user root from the attached keyboard and monitor. By default, there is no password on the console. If you used a UBOS staff, you can log in over the network instead as described here.

  8. Now: wait. UBOS needs to generate a few cryptographic keys before it is ready to use and initialize a few other things on the first boot. That might take 5 or 10 minutes. To determine whether UBOS ready, execute:

    > systemctl is-system-running

    Wait until the output has changed from starting to running. If it is anything else, consult troubleshooting.

  9. If you have Ethernet plugged in, and your network has a DHCP server (most networks do), your computer should automatically acquire an IP address. You can check with:

    > ip addr

    Make sure you are connected to the internet before attempting to proceed.

  10. Update UBOS to the latest and greatest:

    > ubos-admin update
  11. You are now ready to set up your first app and site.
