GK107M [GeForce GT 750M]
Fresh new Ubuntu install, I can’t update my graphics card drivers.
W: GPG error: Index of /compute/cuda/repos/ubuntu2004/x86_64 InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY A4B469963BF863CC
E: The repository ‘||EDIT: The above link was here as well, but new users are only allowed to post one link|| InRelease’ is not signed.
(The repository was picked by Ubuntu, not me.)
Yes… I know, it’s an nvidia .com website issue. The Chat support people (Windows only) insisted that I needed to come here and report it.
Well, technically I did have 3 “Additional Driver” options to pick from:
NVIDIA binary driver - version 340.108 (proprietary-tested)
NVIDIA driver metapackage from nvidia-driver-390 (proprietary)
NVIDIA Server Driver metapackage from nvidia-driver-418-server (proprietary)
I chose the proprietary-tested, assuming that that one probably wouldn’t cause Gnome to crash and burn.
