I have a working installon of MySQL 5.5.28 on rhel 5 with XtraBackup 2.0.4
If I try to upgrade to MySQL 5.5.29 there is an error
rpm -Uhv MySQL-server-5.5.29-2.rhel5.x86_64.rpmerror: Failed dependencies: mysql is needed by (installed) percona-xtrabackup-2.0.4-484.rhel5.x86_64
NB: this method works fine for the last several upgrades.
If I uninstall Xtrabackup the upgrade works fine and MySQL 5.5.29 is installed and working but then it is not possible to install XtraBackup - the same error message is given.
NB: It is the same with XtraBackup 2.0.3 as well.
