Fail to install tensorrt8.2.5.1

Hi,
I want to install TensorRT8.2.5 on ubuntu20.But I’ve installed a different version before and removed it.The CUDA version is 11.6.
Here’s how I do it:

sudo rm /etc/apt/sources.list.d/*cuda*
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/3bf863cc.pub
sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"
sudo apt-get update
sudo dpkg -i nv-tensorrt-repo-ubuntu2004-cuda11.4-trt8.2.5.1-ga-20220505_1-1_amd64.deb
sudo apt-key add /var/nv-tensorrt-repo-ubuntu2004-cuda11.4-trt8.2.5.1-ga-20220505/82307095.pub
sudo apt-get update
sudo apt install tensorrt


How can I uninstall the remnants of other versions?
