Authentication plugin \'caching_sha2_password\' cannot be loaded: dlop

Answer 1

Note: For Linux (Debian, Ubuntu, Mint)

I got this error:

MySQL Error Message: Plugin caching_sha2_password could not be loaded: /usr/lib/x86_64-linux-gnu/mariadb19/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory

I solved with this steps:

1. Enter on mysql console: $ mysql -u root -p, if you don't has a password for root user, then:

2. Use mysql db: mysql> use mysql;

3. Alter your user for solve the problem: mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

4. Exit... mysql> quit;

5. Done!
