with the current develop installation (freshly pulled on a vanilla Debian 9 system using the easy install script), the setup wizard does not complete but fail with
Could not start up: Error in setup
There are no errors in the console, nor in the bench console on the server… Any clues?
Turns out this was an access permission issue: in the develop instance, all files need to be owned by the user that runs frappe. This command will clear this and it will go through (where user is the user):
$ cd /home/user/frappe-bench
$ sudo chown -R user:user *
Maybe this helps someone having the same issue.
