This bug is about installing on a system with a different version of binutils. I assumed that is what you are doing because that is what this bug is about. But based on your comment @khteh, I now assume that you are not hitting the problem I reported. Do you have a reason to believe your issue is caused by binutils, or are you just seeing this same error message?
modprobe: ERROR: could not insert 'nvidia': Key was rejected by service binutils version differences is not the only reason you might see that error. You may be having an issue unrelated to this bug. One possibility is that the installation method you selected is trying to build its own version of the module, which is not signed by a trusted Canonical key. The fact that you have a make.log at all (as shown in comment #19) is a hint there. nvidia-driver-535 will try to install the prebuilt and signed modules where possible, but if it can't, it will revert to installing the "source" and building an unsigned one instead. If you have the nvidia-dkms-535 driver installed instead of linux-modules-nvidia-535-generic, then that may be what happened. If that is the case, you can try switching to the prebuilt/signed one by running: sudo apt install nvidia-driver-535 linux-modules-nvidia-535-generic sudo apt remove nvidia-dkms-535 # ^ That should only remove nvidia-dkms-535 I hope that fixes your system. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-restricted-modules in Ubuntu. https://bugs.launchpad.net/bugs/1921536 Title: "modprobe: ERROR: could not insert 'nvidia': Key was rejected by service" due to binutils mismatch Status in linux package in Ubuntu: Confirmed Status in linux-restricted-modules package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-525 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-535 package in Ubuntu: Confirmed Bug description: If a user does not have the same version of binutils installed as the one used to produce the nvidia module signature, the module generated at postinst maybe unloadable: modprobe: ERROR: could not insert 'nvidia': Key was rejected by service I ran into this when I tried to install the hirsute kernel/nvidia driver on a focal system.
