Machine no more boot with Secure Boot enabled

[outofsight]

I made a mess .

I was trying to enable support for my Intel WLAN+BT adapter, I added firmware files, I run an

update-initramfs...

as per some instruction.

Wlan adapter still doesn't work, and the system no more boot if Secure Boot is enabled because "the boot image cannot be authenticated". It seems that there are other negative side effects.

I would like to restore the previous situation.

Is that possible and easy?

do you mean your host? as in pve? that could have never been booted with secure boot, because our kernel is not signed...

Yes, i mean the PVE host.
After what I did, I found PVE host not booting, and checking System Setup, Secure Boot was enabled.
If PVE requires Secure Boot disabled, it was disabled when I installed and the only remaining explanation is that something enabled yesterday.
I'll need to investigate.
Thanks
