After reviewing main.log and some googling, I stumbled upon https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- upgrader/+bug/1769184 in which it was suggested that "unity" might be the issue. So I removed unity and retried, and at this point the upgrade seems to be running. I think my main issue at this point is exactly what is said in https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- upgrader/+bug/1769184/comments/9 (i.e. I really wish I had gotten an warning message about unity, rather than just "aborting") but I'm okay if you decide to close this as a duplicate of 1769184
