When setting up a repository with a custom admin user Like thus:

fossil init --admin-user=myadmin test.fossil

I get the error:

Cannot figure out who you are! Consider using the --user
command line option, setting your USER environment variable,
or setting a default user with "fossil user default USER".
fossil: cannot determine user

This did however work on Ubuntu's default version 1.21. What changed and what am I doing wrong?

Not setting a user simply works.

OS: Ubuntu 12.04.1-64
