Hello ,

I was building docker image and I had a issue and this issue is the following : “ ERROR [ 2/26] RUN apt update && apt install -y --no-install-recommends build-essential autoconf libtool git ccache curl wget pkg-config sudo ca-certificates automake libssl-dev bc python3-dev python3-pip google-perftools gdb libglib2 2.6s

and before exiting the build I receive :

Apparently NVIDIA changed the encription key and thus, we have these errors.

So I tried to fix it by reinstalling the right key using your methode Notice: CUDA Linux Repository Key Rotation But I have always the same issue.

Could you please tell me what to do next to fix the key rotation.


  • the new key is in fact installed (after removing the old one obviously) :
    • (Reading database … 167379 files and directories currently installed.)
      Preparing to unpack cuda-keyring_1.0-1_all.deb …
      Unpacking cuda-keyring (1.0-1) over (1.0-1) …
      Setting up cuda-keyring (1.0-1) …
      A deprecated public CUDA GPG key appear to be installed.
      To remove the key, run this command:
      sudo apt-key del 7fa2af80
  • For the $distro/$arch
    • I am using ubuntu2004/sbsa

Thank you in advance.
Best regard,
