I’m working on a handful of servers that all have the same problem: when running yum, an error message appears that tells me a package called ntpupdate needs to be upgraded, but somehow this doesn’t work and the package is being skipped. Then follows a huge list of duplicate packages that are installed on those systems (probably installed by the automatic package updater within Plesk).
From time to time, the yum package manager may encounter issues with duplicate packages that are erroneously installed on a system. This manifests in a yum update going awry, telling us something along the lines of this:
I’ve just tried to update one of my CentOS 6.2 servers that was built from an older AMI, only to find that the yum update command stopped unexpectedly with several dependency errors. They all pointed to something called “qpid”, and I must admit that I’ve never heard of it – nor did I know that it was installed.
The long list ended with the following suggestion:
Youcould try using--skip-broken to work around the problem
Youcould tryrunning: rpm-Va--nofiles--nodigest
And why not indeed, since yum is so nice to give us suggestions. I’ve tired running “yum update –skip-broken” and got the following message:
Every once in a while it can happen happen that use use “yum update” to update your Linux system.
Usually this works without a hitch, but you may have come across a message such as this:
Setting up Install Process
There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.
The program yum-complete-transaction is found in the yum-utils package.
But what does this mean, and how do we alleviate this?
