The public CUDA GPG key does not appear to be installed.
To install the key, run this command:
sudo apt-key add /var/nv-tensorrt-repo-ubuntu2004-cuda11.4-trt8.2.2.1-ga-20211214/7fa2af80.pub
This is complete non-sequitur. My questions was about the installation process and deprecated keyring which in effect is still not deprecated. How am I supposed to have txtexec w/o a functional trt install?
The old keys are not valid anymore and need to be updated before the repos will work.
Have a look at the instructions here : Notice: CUDA Linux Repository Key Rotation , I hope they help.
The install instructions you linked also has some instructions to install new key:\https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#ubuntu-installation
Please let us know if any of those instructions failed.
once the new keys have been installed, hopefully everything will be OK
Thank you. The instructions seem to/should work. The tensorRT version requires cuda <=11.4 and >=11.0. But I opened this issue mainly to just let you guys know that a deprecated keyring is still useful in the install.
