Web installer stuck

So I made a typo. Silly me. One letter wrong in the DB password, and now the web installer is confused and has no idea what to do, except to tell me to “try again”. Which I would. If there was a way to:

A. Go back.
B. Restart the web installation
C. Try again.

I am sure there is an undocumented way of redoing the web install. Honestly, “rm -rf /opt/librenms” does not seem very inviting.
