This is because previous “yum update” failed for some reason after package install. So no cleanup was done.
To fix, you need to use package-cleanup command.
|
1 |
yum install yum-utils |
To list all duplicate packages, run
|
1 |
package-cleanup --dupes |
To remove all duplicate packages, run
|
1 |
package-cleanup --cleandupes |
Now do a yum update
|
1 |
yum update |
This will update your system and install any missing packages.
To verify if there any problem, run
|
1 |
package-cleanup --problems |
If this does not fix, try yum fix duplicate package error
See yum
