Software Fails to Be Upgraded on the Atlas 500 AI Edge Station (Model 3000) WebUI and a Message "Middleware upgrade failed" Is Displayed

Symptom

The software fails to be upgraded on the Atlas 500 AI edge station (model 3000) WebUI and a message "Middleware upgrade failed" is displayed.

Possible Causes

The space of the /opt/middleware directory is insufficient.

Procedure

1. Log in to the Atlas 500 CLI using SSH.
2. Run the develop command to enter the development mode.
3. Run the df -h command to check the available space of the /opt/middleware directory (the value in the Avail column).

   400 MB space is at least required for firmware upgrade. If the available space is less than 400 MB, the space is insufficient. Go to 4.

4. Delete unwanted files from the /opt/middleware directory to release space. Ensure that the available space of the directory is greater than 400 MB.
5. Upgrade the software package again.
