My dashboard is empty

Hi, I just installed ERPNext manually in my ubuntu machine.
After several issues, I finally managed to install it correctly.
Everything looks fine but when I execute “bench start” there is no ERP (stock, clients, etc) in there.

My desktop looks like this:

I tried to install it from the gui but no look. In the console there is the following error:

ERPNext can only be installed on a fresh site where the setup wizard is not completed
| You can reinstall this site (after saving your data) using: bench --site [sitename] reinstall

I executed “bench --site site1.local reinstall” and it is always the same story.

Please your help.

@spiralni bench install-app erpnext

hi @max_morais_dmm, thanks, I already executed these steps.

bench init frappe-bench
cd frappe-bench
bench get-app erpnext https://github.com/frappe/erpnext         # Add ERPNext to your bench apps
bench new-site site1.local                      # Create a new site
bench install-app erpnext                       # Install ERPNext for the site 

If I execute “bench install-app erpnext” again, I obtain this message

Installing erpnext...

ERPNext can only be installed on a fresh site where the setup wizard is not completed
You can reinstall this site (after saving your data) using: bench --site [sitename] reinstall

Never mind, I just reinstalled everything from scratch and it worked.
Thanks.
