When trying to upload a newly created repository by doing the following:

- from the dashboard, click on "Create Repository"
- then click "Upload Repository"
- enter simple name and password
- check "Make this repository private"
- upload the repo file
- press "Upload Repository"

I get the following error:
\  
\  
<p style="color:red;">Something failed during the creation process please try again. Error:</p>
```
Failed to create new user
```

Extra Informations:
   
- I've installed flint on my ubuntu 18.04 workstation and I got same error.

- I found out that it fail because the user it try to create already exist in the repository.
    + I think it should handle this situation somehow, it is probably very common that an uploaded repository already contain the "Flint Account" username.

- I tried again on Chiselapp with a repo which doesn't contain a user that match my chiselapp account.
    + But it still does the same error. (as the opposite as on my own flint setup)

A have exactly the same problem. Changing the repo username doesn't help.
