There are some odd errors in UbiquitySyslog.txt I haven't seen before:

Mar 19 04:38:51 ubuntu user-setup: adduser: Only one or two names allowed.
Mar 19 04:38:51 ubuntu ubiquity: chpasswd: (user ) pam_chauthtok() failed, error:
Mar 19 04:38:51 ubuntu ubiquity: Authentication token manipulation error
Mar 19 04:38:51 ubuntu ubiquity: chpasswd: (line 1, user ) password not changed

Could you please tell us more about exactly how you filled in the User Setup screen? Did you use any special characters, or something with spaces under the username field?

Name entered was "localadmin" without the quotes
Machine name was "vader-l"

Don't believe I made any typos. I did a minimal install following this, but with multiple changes. I first made sure to remove the btrfs '@' subvolume and I also did a minimal install with no updates downloaded. If I had to make an educated guess I'd say it was the existing install causing conflicts. "localadmin" was a user that existed in the previous install.

Oh, forgot to mention, the second installation attempt with previous installation removed succeeded without error.
