Public bug reported: I have installed percona-xtradb-cluster-server-5.6 on my Xenial server and try to set the root password with mysqladmin:
# mysqladmin --user=root --password='' password 'secure' mysqladmin: [Warning] Using a password on the command line interface can be insecure. Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety. mysqladmin: unable to change password; error: 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '() IDENTIFIED BY 'secure'' at line 1' So it looks the version 5.7 of mysqladmin is not compatible with version 5.6 any more, but mysql-client-5.6 package has also been dropped from Xenial shortly before release. # apt policy mysql-client mysql-client: Installed: 5.7.11-0ubuntu6 Candidate: 5.7.11-0ubuntu6 # apt policy mysql-client-5.6 mysql-client-5.6: Installed: (none) Candidate: (none) # apt policy percona-xtradb-cluster-server-5.6 percona-xtradb-cluster-server-5.6: Installed: 5.6.21-25.8-0ubuntu3 Candidate: 5.6.21-25.8-0ubuntu3 The same command still worked on Xenial Beta with mysql-client-5.6 available. ** Affects: percona-xtradb-cluster-5.6 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574509 Title: mysqladmin-5.7 fails to set password for percona-xtradb-cluster- server-5.6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/percona-xtradb-cluster-5.6/+bug/1574509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
