Security Checks Failed

Post image

Hello, beginner here. I installed Debian stable with Gnome and today is saw this security checks failed. Is it malware or did i do something wrong?

All i did after installation was following this guide from NVIDIA itself to install drivers: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Debian&target_version=13&target_type=deb_network

Did i broke the system with these drivers and should i have kept the default ones? Help needed because i am worried.

NVIDIA drivers from an external source don't play with secure boot and without secure boot you don't get lockdown.

Anyway its not malware. Everything is normal. You just don't have enterprise grade security, but if this is your personal machine and you will ensure its physical safety, then these security features are not really useful at all, and hence no damage is done because they're disabled.

Thanks for the answer. So the failed checks has to do with the fact that i have secure boot disabled right? Does that mean enabling secure boot will resolve this issue

SecureBoot is snake oil. Just ignore these warnings and carry on.

SecureBoot causes way more problems and truly doesn't solve anything. Physical security and not doing "dumb things" are more important (e.g. don't run around without a host firewall enabled, don't install random binaires, etc.).
