This looks like the relevant line:
Parts processing error: Failed to copy '/root/parts/charm/src/.tox/unit/log/unit-0.log': no such file or directory.
I was able to remove that temp dir from the charm source directory, and delete the lxd container to get the charm building again, and I'll prevent it from happening again with `.jujuignore`. However, I'm unsure why this was breaking things in the first place, as other charms in the bundle were building fine with a `.tox` directory in them.
