Hi, I just made a quick and dirty workaround by editing
I replaced this line:
by this line:
req.add_header("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.67 Safari/537.36")
Afterwards install went through without 403 error:
[18:10 xs ~]# secureboot-certs install default default default latest
Successfully installed certificates to the XAPI DB for pool.
