This suggest you ran into an Ubuntu bug from a recent update to bzip2 which causes checksum errors (this is part of Ubuntu, it isn’t specific to SDK Manager or JetPack):
https://devtalk.nvidia.com/default/topic/1056381/jetson-agx-xavier/jetpack-4-2-xavier-install-failed/

that seems to indicate a failure to install opencv to a host;
I am getting the error all the time because I have custom opencv installed at the host and therefore it causes the error. However, the error doesn’t impact installation to Xavier device to that opencv should get installed despite the error installing it to the Host PC. Thus if you do not need opencv at the Host and at Xavier only you may disregard the error, that merely is an indicator of that opencv failed installing to the Host, as it seems to me.
