I am trying to upgrade MySQL from 5.6 to 5.7 using the yum repository. During my first attempt there was a conflict of dependencies, so I did yum remove perl-DBD-MySQL which also removed percona-toolkit. After seeing the upgrade succeed and MySQL restart successfully, I tried to reinstall percona-toolkit. Here are the results: yum install percona-toolkit Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile - base: [mirror.solarvps.com](http://mirror.solarvps.com) - epel: [mirror.cogentco.com](http://mirror.cogentco.com) - extras: [mirror.beyondhosting.net](http://mirror.beyondhosting.net) - updates: [repo1.dal.innoscale.net](http://repo1.dal.innoscale.net) Resolving Dependencies → Running transaction check —\> Package percona-toolkit.x86\_64 0:3.0.4-1.el7 will be installed → Processing Dependency: perl(DBD::mysql) \>= 1.0 for package: percona-toolkit-3.0.4-1.el7.x86\_64 → Running transaction check —\> Package perl-DBD-MySQL.x86\_64 0:4.023-5.el7 will be installed → Processing Dependency: libmysqlclient.so.18(libmysqlclient\_18)(64bit) for package: perl-DBD-MySQL-4.023-5.el7.x86\_64 → Processing Dependency: libmysqlclient.so.18()(64bit) for package: perl-DBD-MySQL-4.023-5.el7.x86\_64 → Running transaction check —\> Package Percona-Server-shared-56.x86\_64 0:5.6.36-rel82.1.el7 will be installed → Finished Dependency Resolution Dependencies Resolved # ========================================================================================================================= Package Arch Version Repository Size Installing: percona-toolkit x86\_64 3.0.4-1.el7 percona-release-x86\_64 4.8 M Installing for dependencies: Percona-Server-shared-56 x86\_64 5.6.36-rel82.1.el7 percona-release-x86\_64 619 k perl-DBD-MySQL x86\_64 4.023-5.el7 base 140 k # Transaction Summary Install 1 Package (+2 Dependent packages) Total size: 5.5 M Installed size: 5.7 M Is this ok [y/d/N]: y Downloading packages: Running transaction check Running transaction test Transaction check error: file /etc/my.cnf from install of Percona-Server-shared-56-5.6.36-rel82.1.el7.x86\_64 conflicts with file from package mysql-community-server-5.7.19-1.el7.x86\_64 ## Error Summary yum list installed|grep -i MySQL shows: mysql-community-client.x86\_64 5.7.19-1.el7 @mysql57-community mysql-community-common.x86\_64 5.7.19-1.el7 @mysql57-community mysql-community-libs.x86\_64 5.7.19-1.el7 @mysql57-community mysql-community-server.x86\_64 5.7.19-1.el7 @mysql57-community mysql57-community-release.noarch el7-10 I’m not sure how to resolve the dependency or why the Transaction check error refers to /etc/my.cnf. Has anyone else experienced this? Thanks, Paul ---

Can you share the output of: $ rpm -qa | egrep -i “percona|mysql” ---

I tried a few things and some googling, ended up installing mysql-community-libs-compat-5.7.19-1.el7.x86\_64 with yum localinstall. After that percona-toolkit installed fine. RPM output below: rpm -qa | egrep -i “percona|mysql” mysql-community-libs-compat-5.7.19-1.el7.x86\_64 percona-release-0.1-4.noarch mysql-community-client-5.7.19-1.el7.x86\_64 percona-toolkit-3.0.4-1.el7.x86\_64 mysql-community-libs-5.7.19-1.el7.x86\_64 perl-DBD-MySQL-4.023-5.el7.x86\_64 mysql57-community-release-el7-10.noarch mysql-community-server-5.7.19-1.el7.x86\_64 mysql-community-common-5.7.19-1.el7.x86\_64 Thanks for the response. ---

I’ve met the same issue trying to install percona-toolkit 3.0.5 along with percona-server-server-5.7 it looks like packages depends on conflicting mysql conector libraries Is there a way to resolve it ? Any info on fixes in further releases ? ---

You should install perl-DBD-MySQL in the following way: yum install perl-DBD-MySQL --disablerepo percona-release\* and after that please try to install percona-toolkit ---
