Hello ERPNEXT team,
I’m totally new in erpnext, I want to install in on ubuntu 18.10 all the steps I followed and worked properly. Steps I followed from this link .

At last step I’m getting one MySql Error (Traceback (most recent call last):

. If anyone can help that would be great.

Thank you

This will help, Follow this steps

  1. even the URL does not mention ubuntu 18.10. So generally (even though I couildn’t say that 1810 actually is the cause of your problems) it’s a good idea to use what is officially supported and that are the LTS versions of ubuntu. So, I’d recommend to use a 18.04 server rather then 18.10
  2. there is one step missing in that guide in my eyes and that is to remove the erpnext user from the sudo group after the installation. This is a security measure and sudo rightsd are not required to run, nor update erpnext

The quick fix is…

mysqladmin -uroot password ‘YourPasswordHERE’
mysql -uroot -pYourPasswordHERE -Bse “GRANT ALL PRIVILEGES ON . TO ‘root’@‘localhost’ IDENTIFIED BY ‘YourPasswordHERE’ WITH GRANT OPTION;”

you might also need to add the LAN/subnets etc

mysql -uroot -pYourPasswordHERE -Bse “GRANT ALL PRIVILEGES ON . TO ‘root’@‘192.168.%.%’ IDENTIFIED BY ‘YourPasswordHERE’ WITH GRANT OPTION;”

mysql -uroot -pYourPasswordHERE -Bse “GRANT ALL PRIVILEGES ON . TO ‘root’@‘127.%.%.%’ IDENTIFIED BY ‘YourPasswordHERE’ WITH GRANT OPTION;”

If you have a MariaDB root password then you could use it on the command line during the install or perhaps add it to /root/.my.cnf to get past this.

If you don’t have one it might be because you are using a socket for root authentication, if this is the case you have to set one (I haven’t found a way to avoid this, but perhaps it is possible), see this article:

thank you for your reply I even tried it on 18.04 then also getting the same error.

The solution provided by @trentmu will solve your issue.

Thank you for your response and it worked
