"libcudnn.so.8: file too short" running Pytorch in docker

Actually at the beginning I didn’t encounter this problem, it appeared later.

Hmm…had you recently done an apt upgrade by chance?

If so, can you try the steps from this post?

Docker isn't working after apt upgrade

I followed the instructions from: https://github.com/dusty-nv/jetson-containers/issues/108 https://forums.developer.nvidia.com/t/docker-containers-wont-run-after-recent-apt-get-upgrade/194369/11 I combined the instructions, with a revision to the /etc/apt/preferences section and here they are: wget https://launchpad.net/ubuntu/+source/docker.io/20.10.2-0ubuntu1~18.04.2/+build/21335731/+files/docker.io_20.10.2-0ubuntu1~18.04.2_arm64.deb sudo dpkg -i docker.io_20.10.2-0ubuntu1~18.04.2_arm64.de…

Also, here is what my libcudnn looks like on L4T R32.6.1:

# outside of container
ls -ll /usr/lib/aarch64-linux-gnu/libcudnn.so.8*                                          
lrwxrwxrwx 1 root root     17 May 24  2021 /usr/lib/aarch64-linux-gnu/libcudnn.so.8 -> libcudnn.so.8.2.1
-rw-r--r-- 1 root root 162280 May 24  2021 /usr/lib/aarch64-linux-gnu/libcudnn.so.8.2.1

# inside l4t-ml container
ls -ll /usr/lib/aarch64-linux-gnu/libcudnn.so.8*
lrwxrwxrwx 1 root root     17 Dec  2 17:08 /usr/lib/aarch64-linux-gnu/libcudnn.so.8 -> libcudnn.so.8.2.1
-rw-r--r-- 1 root root 162280 May 24  2021 /usr/lib/aarch64-linux-gnu/libcudnn.so.8.2.1

How does it look for you?
