In your ~/.nvsdkm/logs/DRIVE_OS_5.2.0.0_SDK_Linux_OS/NV_TENSORRT_HOST_CROSS_LINUX_COMP.log,
“sudo apt-get update” output doesn’t contain any /var/nv-tensorrt-repo-cuda10.2-trt6.3.1.3-d5l-cross-ga-20200724 lines. It’s abnormal and should be an environment issue.
A possible solution is to manually remove all cuda/tensorrt packages. Make sure the output of “dpkg -l | grep cuda” command is absolutely empty. Then retry installation with SDKM. Thanks.
