Image-based OTA package generation failing

[mxp]

Hi, all. I’m currently trying to generate an OTA update image to upgrade a system running 35.2.1 to 35.3.1. I’m using a freshly-generated sample filesystem for each of them, and I’ve followed along with the instructions here. The payload generation completes with the following errors:

t19x payload generation complete with 4 failure(s)

I’ve removed my username and project name, just for privacy purposes. Any help would be greatly appreciated.

The problem was that the install scripts call python, rather than python3, so I installed python-is-python3, in order to create a symlink from the python command to python3. Alternatively, one could edit the scripts directly.
