I have the same error after upgrading to MySQL 8.0

[pierot]

We occasionally run into the same error.

[dragonwasrobot]

Can also confirm that the error happens when upgrading to MySQL 8.0, it disappears when downgrading to MySQL 5.7.

I thought I was the only who is having the same error while following the tutorial using mysql Ver 8.0.11 for Linux on x86_64 (MySQL Community Server - GPL) but everything seems to be working fine if I use MariaDB 10.3

$ mix ecto.create

I can't find this info anywhere, but looks like currently mariaex doesn't support MySQL 8.0.x? Can anyone from maintainers confirm it?

[sigu]

Seems like it, while running a gitlab CI task it kept failing on the same but after downgrading to mysql:5.7 now everything is working as expected

MySQL 8 changes the default authorization plugin, to wokraround you need to to start MySQL with parameter: --default-authentication-plugin=mysql_native_password or include this in your my.cnf:

[mysqld]
default-authentication-plugin=mysql_native_password

[sahilpaudel-pe]

I am facing this intermittently with mysql:5.7 as well, it goes away when I deploy again only to comeback again later.
