Update Small Devices (<20GB) via USB
Update the Desktop on small devices (<20GB storage) with a USB drive.
Warning
If you manage both standard desktops and mini devices, you must update the standard desktops first before updating the mini devices.
Prepare the USB Drive (if needed)
Before updating, ensure your USB drive contains the desktop-mini update files. If not, prepare it on a computer that already has the updates.
Verify Update Exists Locally
Verify the desktop-mini component is available locally. This is the special version for small devices.
# Check for the mini desktop component
tl-comp-latest desktop-miniIf the component is not there, pull it from the bastion first.
Transfer Files to USB
Mount your USB and copy the desktop-mini and admin components to it.
# Mount the 4th partition of your USB drive
sudo mount /dev/sdx4 /mnt
# Create the destination directories
mkdir -p /mnt/desktop /mnt/admin
# Transfer the mini desktop and the admin component
rsync -avP /srv/desktop-mini/vX.X.X* /mnt/desktop/
rsync -avP /srv/admin/vX.X.X* /mnt/admin/Note
Replace vX.X.X with the actual version number you found.
Unmount the drive when done:
# Unmount the drive safely
sudo umount /mnt Install the Update
Once your USB is prepared (or if it was already updated), you can install the update.
Boot from the USB Drive
Restart the computer and boot from the prepared USB drive. This process varies by device.
Execute the Update
From the USB environment, run the update command, targeting the computer’s internal drive (e.g., /dev/mmcblk0 or /dev/sda).
# Update an existing TechLit system
tl-hw-update-desktop /dev/mmcblk0 Tip
If the above command fails or you want to do a completely fresh installation, you can use tl-hw-prepare instead. See the device provisioning guide for more details.
Complete the Update
After the command finishes, reboot the computer.
reboot
