yum cannot resolve conflicts when trying to install Percona Server 5.7 when Percona Server 5.6 is currently installed

[Jaime Sicam]

Currently, Percona 5.6 is installed:

# rpm -qa|grep Percona
Percona-Server-shared-56-5.6.35-rel80.0.el7.x86_64
Percona-Server-client-56-5.6.35-rel80.0.el7.x86_64
Percona-Server-server-56-5.6.35-rel80.0.el7.x86_64

Try installing 5.7 with yum:
[root@c7 ~]# yum -d 0 -e 0 -y install Percona-Server-server-57-5.7.16
Error: Percona-Server-shared-compat-57 conflicts with Percona-Server-shared-56-5.6.35-rel80.0.el7.x86_64
Error: Percona-Server-client-57 conflicts with Percona-Server-client-56-5.6.35-rel80.0.el7.x86_64
Error: Percona-Server-server-57 conflicts with Percona-Server-server-56-5.6.35-rel80.0.el7.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
[root@c7 ~]# yum -d 0 -e 0 -y install Percona-Server-client-57-5.7.16
Error: Percona-Server-shared-compat-57 conflicts with Percona-Server-shared-56-5.6.35-rel80.0.el7.x86_64
Error: Percona-Server-client-57 conflicts with Percona-Server-client-56-5.6.35-rel80.0.el7.x86_64

It would be ideal the package manager can automatically resolve this issue by uninstalling Percona-Server-56 and upgrade them to Percona-Serer-57

[Jaime Sicam (jssicam)]

A workaround would be to create several yum repositories for each major version of Percona Server.
eg.
percona-57.repo
percona-56.repo
percona-55.repo
percona-51.repo

Here is the instruction on how to update from Percona-Server-56 to Percona-Server-57:
https://www.percona.com/doc/percona-server/5.7/upgrading_guide_56_57.html

[Sveta Smirnova (svetasmirnova)]

There is inconsistency with how upgrade handled on DEB-based systems (Xenial).

[Sveta Smirnova (svetasmirnova)]

Thought this is consistent with MySQL upgrade process.

Percona now uses JIRA for bug reports so this bug report is migrated to: https://jira.percona.com/browse/PS-1065
