The 550 driver does not have corresponding signed binaries, so the dkms driver gets installed instead. This requires MOK enrollment in order to boot under secureboot.
The 550 driver claims to support ALL of the devices that are supported by 535: $ join -v2 <(grep-dctrl -n -FPackage -X nvidia-driver-550 -sModaliases /var/lib/apt/lists/*_noble_*binary-amd64_*Packages | sed -e's/nvidia(//; s/)//; s/, /\n/g' | sort -u) <(grep-dctrl -n -FPackage -X nvidia-driver-535 -sModaliases /var/lib/apt/lists/*_noble_*binary-amd64_*Packages | sed -e's/nvidia(//; s/)//; s/, /\n/g' | sort -u) $ And ubuntu-drivers defaults to installing the newest driver that supports the cards, so tries to install 550, not 535. Either 550 needs to not declare support for these cards, or it needs to be included in the modules that we deliver signatures for. Until we have a resolution in one of those two ways, I am demoting this package to noble-proposed and blocking it there. ** Tags added: block-proposed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060852 Title: nvidia-driver-550-open fails with secure boot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-550/+bug/2060852/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
