apt fail to install container-toolkit - gpg public key not available

[denis-roy-cima]

Good day @elezar

Trying to install nvidia-container-toolkit by following this guide: https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html

After pasting this command:

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

apt-get update yields this error message:

W: GPG error: https://nvidia.github.io/libnvidia-container/stable/deb/amd64  InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DDCAE044F796ECB0
E: The repository 'https://nvidia.github.io/libnvidia-container/stable/deb/amd64  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.

It might have something to do with the fact that the GPG key is expired:

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | gpg
gpg: WARNING: no command supplied.  Trying to guess what you mean ...

Thanks!
