Using Fedora as example but similar for other Linux: Install MySQL Yum Repository Example for Fedora: shell > sudo dnf -y install https://dev.mysql.com/get/mysql80-community-release-fc31-1.noarch.rpm shell > sudo yum --disablerepo= \* --enablerepo= ' mysql*-community* ' list available Then choose the package you want to install/upgrade, such as: shell > sudo yum -y install mysql-community-{client,server} Finally we can check the version: $ mysql --version mysql Ver 8.0.19 for Linux on x86_64 (MySQL Community Server - GPL) $ mysqldump --version mysqldump Ver 8.0.19 for Linux on x86_64 (MySQL Community Server - GPL)
