Even with the easy install script, installing ERPNext has been terrifyingly error-ridden. I’m on my third attempt already following several server formatting due to failed ERPNext installation.
My current error has to do with MySQL root permission issue, even when it was your script that installed MySQL on my system in the first place, and as such should know to set and use the root password.
My previous installations failed for similar reasons, and my attempt to remove your MariaDB installation was completely impossible.
Just a little more effort and I’ll give up completely on ERPNext. How difficult an installation script be? SMH!
