SOLVED: Secure boot clean install on NUC

[fonze98]

I am wondering if any has successfully performed a clean install of Proxmox 8.1 on an Intel NUC 13th gen with secure boot enabled? I was attempting to set up a new cluster this morning but upon trying to boot from the USB installer, I am getting a "Secure Boot Violation, Invalid signature detected" error

So I went ahead and installed with Secure boot disabled and then performed the steps outlined in the Secure Boot Upgrade write up and that works fine after re-enabling secure boot so it seems like something may not be included in the installer that is needed?

how did you transfer the ISO to the USB drive? you need to copy it as-is (bitwise, with dd or a similar tool), not using a tool like ventoy/rufus/..
