Cannot login to a new Galette instance

What app is this about, and its version: galette 1.2.1~ynh1
What YunoHost version are you running: 12.1.39
What type of hardware are you using: Other ARM board

Describe your issue

I installed and selected one of the users to be administrator on the install page. Installation was successful, but I could not login with the user and password I set on the install page. I tried both username and username@local.tld with same login error. Just in case I had mistyped something in initial setup, I uninstalled and reinstalled again. I am still unable to login.

I struggle to find anyway to reset the user or password from CLI.

I think we have an error in install script, and I am happy to investigate whatever clues you might provide. Thank you very much.

It looks like a bug…
Try this : go to https://yourgalettedomain/galette/installer.php(or https://yourgalettedomain/installer.php if you installed it at the root) and reinstall using the db password in the /etc/yunohost/apps/galette/settings.yml. You should then be able to create an admin user.
Once done, delete or move /var/www/galette/galette/webroot/installer.php or anyone will be able to modify again your instance !!
