Mysql file import on arm64 gives access denied for user 'root'@'localhost'

Using mysql file import does not grant the root user access:

mysql -uroot < sql/create_mysql.sql

While the execution as root user works as expected:

mysql -uroot -e 'SHOW DATABASES;'

The problem is illustrated in the following repository:
https://travis-ci.org/github/damaex/travis-test

I’m not quite sure if this has anything to do with the different mysql version on arm64, but on amd64 everything works as desired.

Furthermore the output of the mysql command is different.

amd64:
