I just created a VM with Ubuntu 12.04 and followed the installation setup, using the “Easy Mode” to install all prerequisites and then installed frappe and ERPNext.
Everything worked flawless. Then I started bench using:
bench start
and then pointed to http://localhost:8000 in my browser. Got the login screen, but when I tried to login using Administrator/admin it failed with an “Invalid Login” message.
Thanks, the password I setted during install worked. I now can login and the setup wizard is launched. I entered my personal info, keeping Administrator as user name, entered all initialisation data, but got this error at the end of the process:
I found what I was doing wrong. I first assumed that the wizard was asking to complete the personal info for the Administrator user, but doing that failed with the first error message I posted. After that I assumed that the wizard was asking the info to create another user, so I tried to set a differente username but the wizard didn´t accept any value on that field… until I realized, today, that the wizard was asking for an EMAIL ADDRESS and not an USER ID!! Once I entered a valid email (and one different from the one associated to the Adminstrator user) it worked like a charm!!
Maybe this could work: change input name for User Id and Password on Wizard´s User Profile page, to avoid browser´s autocomplete to assign Administrator name automatically. This was the fact that lead me to think that I was supossed to complete Administrator account info.
I also think on change the invalid user id error message, but I now realized that the text is perfectly clear: it was me not really reading the error message what caused the problem.
