ERROR 1293 (HY000) SQL

[NikNikYkt]

Hi!
I need help! I trying install umami on my vps server on Centos 7 with mysql Ver 15.1 Distrib 5.5.68-MariaDB, for Linux (x86_64) using readline 5.1, but when I enter the command mysql -u username -p databasename < sql/schema.mysql.sql (all variable data specified correctly), I see error:
ERROR 1293 (HY000) at line 7: Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause

on my own I tried the following:
Open in redactor file sql/schema.mysql.sql and delete 'created_at timestamp default current_timestamp,' and rewrite 'updated_at timestamp default current_timestamp' by 'updated_at TIMESTAMP NOT NULL ON UPDATE CURRENT_TIMESTAMP'
I'm not sure if this is correct. I am a beginner.
