Reply To: Upgrade 1.2.2 issue

I can confirm this error on the 1.1.2 version. I tried upgrading to the newest current version – 1.3.3 and failed via the WebUI.
I can also confirm that the method described above, using SCP and updating via SSH afterwards.

Notice that there might be some garbage files in the /var/tmp directory. Delete only the files and not any folders (if presented).

The device will upgrade and reboot.
