I am unable to Cannot upgrade ESXi 6.7U3 to 7.0.3 U3f using vCLM. Getting the error cannot execute upgrade script on host. I've checked the vua.log and found one error - failed to obtain adapter info. I've checked KB76555 and KB85982 but they don't seem to apply. I am at a dark site and cannot upload logs.
Do you already tried a CLI upgrade?
