Ubuntu 20.04 NVIDIA Driver Update Error
I am trying to
sudo apt-get update
but I am getting the following error:
W: GPG error: https://repo.download.nvidia.com/baseos/ubuntu/focal/x86_64 focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 208CE844D9F220AD
E: The repository 'https://repo.download.nvidia.com/baseos/ubuntu/focal/x86_64 focal InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I have tried the following steps to resolve this issue, but none of them have worked:
- I downloaded and installed the new NVIDIA pubkey using the following command:
sudo apt-key del 7fa2af80
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 208CE844D9F220AD
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x84_64/cuda-keyring_1.0-1_all.deb
sudo dpkg -i cuda-keyring_1.0-1_all.deb
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/3bf863cc.pub
These were my main refereneces to solve the problems. I’ve tried all suggested solutions from the sources. but it doesn’t work.
If the issue is not resolved after taking these steps, what should I do?
I’ll add the full log below
