Error when installing erpnext on fresh ubuntu 16.04 via script

I use a fresh vps with ubuntu 16.04 freshly installed.
I get this error, when using this script: python --develop --user frappe
but the script continues, until it says “Frappe/ERPNext has been successfully installed!”

but why this error?

Seems to be you are entering wrong mysql root password while installtion.
Before starting installation, please verify your mysql root password.
execute mysql -u root -p on your terminal and enter your root password, it should redirect you to MariaDB console if your password is correct, otherwise you’ve to reset the root password.

I didn’t have mysql on my system. I used a clean ubuntu 1604 install.
this seems to be a bug,
see here: How do I uninstall erpnext my server? - #4 by ugommirikwe
any ideas how to resolve?

Seems the issue with mysql root password.

you can reset mysql root password via Set / Change / Reset the MySQL root password on Ubuntu Linux

Thanks @saurabh6790, I followed the instructions in the link,
Then I restarted the script
It gives now this error:

TASK [restart mysql linux] *****************************************************

to retry, use: --limit @develop/install.retry

I think this is a bug n the developer install script
the production install script works fine.
maybe the script should test if there is a mysql, and then handle those cases appropriately

hi @pee

Instructions to change the root password for Mysql/Maria-DB:

1.) Stop MySQL service using sudo service mysql stop
2.) Then execute sudo mysqld_safe --skip-grant-table & command to start the mysql in safe mode and [Hit Enter]
3.) After hitting enter execute mysql -u root command. [You don’t need to enter any password here]
4.) New MariaDB console will be open.
5.) On MariaDB Console execute use mysql and hit enter.
6.) Now you can change the root password using UPDATE user SET password=PASSWORD() WHERE user=‘root’; and hit enter.
7.) Exit from MariaDB console using exit command.

8.) Now stop the mysqld_safe service by killing mysqld_safe service using process id.
9.) Ensure you PID of mysqld_safe by executing ps -aux | grep mysqld_safe command.

10.) Again restart your mysql server using sudo service mysql restart

To Verify use mysql -u root -p. if you redirect to mysql/MariaDB console then congrats you’ve changed the password successfully.

You have to stop the mysql_safe service for Installing ERPNext on your system.
If Your System still throwing the same error while installation then try to reinstall Mysql/MariaDB.
