You shouldn’t need to build the jetson-inference container yourself (unless you want to). For L4T r32.7.2, use the dusty-nv/jetson-inference:r32.7.1 image
It would seem this error is related to this:

It fails due to some GPG error. Any image I base on this image will have errors running `apt update`, which means that `apt update && ...` always fails. A quick google suggests that this is a manual fix of adding a public key (listed in the error message), so is this something that should be added to your image or is it a matter of waiting for someone else to update their public keys?
Try adding this to your docker file before apt update is run:
RUN wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | tee /usr/share/keyrings/kitware-archive-keyring.gpg >/dev/null \
&& echo 'deb [signed-by=/usr/share/keyrings/kitware-archive-keyring.gpg] https://apt.kitware.com/ubuntu/ focal main' | tee /etc/apt/sources.list.d/kitware.list >/dev/null
