So, to summarize, the problem seems to be that the serial console gives me instructions on how to SSH in and complete the installation. But it took, in my case, about 20 minutes before I could actually do so. In the meantime, ssh just failed with the "readlink /snap/subiquity/current" error.
Once I could ssh in, I was able to copy off /var/log - attached.
