Witryna9 sie 2024 · For some reason, IMA believes there is no TPM chip, so it activates a bypass. I'm fairly certain that the entry [ 1.244303] has to happen before IMA is loaded so that IMA knows that there is a TPM chip installed. It's worth mentioning that like the IMA support, TPM support is also built in to the kernel and not loaded as a module.

WitrynaI had the same issue with one of my GCP VM instance. My solution was: Shut down the instance. Click 'Edit' for the instance. Under 'Custom Metadata' section, add 'startup-script' key, with value: #! /bin/bash sudo ufw allow 22. Click 'Save'. Start the instance again, and SSH into it. Hope it helps!
