OS: CentOS6

I was getting a bunch of duplicate package messages when I tried to update one of my servers. It had been a while and I didn’t remember what I might have done, but I suspect that I stopped a yum update in the middle to cause all the duplicates.

Here are a list of commands that I used in the past to get yum working again:

Complete any unfinished transactions, if it was stopped in the middle at some point:

# yum-complete-transaction

Will clean all cached data:

# yum clean all

List duplicate packages:

# package-cleanup –dupes

Remove duplicate packages:

# package-cleanup –cleandupes
