Hi, Query cache support was removed in 8.0 (ref https://dev.mysql.com/doc/refman/8.0/en/mysql-nutshell.html and https://mysqlserverteam.com/mysql-8-0-retiring-support-for-the-query- cache/). Since these two options were in the 5.7 default config we do try to automatically handle it on upgrades, but the default config file location is /etc/mysql/mysql.conf.d/mysqld.cnf, so it only checks that location (/etc/mysql/my.cnf is also used by MariaDB, so by default it just includes the directory for the currently installed variant). The fix for this should simply be to comment out the two lines with query_cache, but if you receive any similar errors after doing that you can check the mysql-nutshell page linked above to see if there's been any change for it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850895 Title: query_cache_limit removed in mysql-8, upgrade broke To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1850895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
