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:
You could try using --skip-broken to work around the problem You could try running: 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:
Packages skipped because of dependency problems:
qpid-cpp-client-0.14-22.el6_3.x86_64 from base
qpid-cpp-client-ssl-0.14-22.el6_3.x86_64 from base
qpid-cpp-server-0.14-22.el6_3.x86_64 from base
qpid-cpp-server-ssl-0.14-22.el6_3.x86_64 from base
qpid-qmf-0.14-14.el6_3.x86_64 from base
Looks like this didn’t quite work either.
The Solution
Turns out this is actually a bug in yum, and it’s been fixed in newer versions of CentOS. All I had to do to make it work is first uninstall both culprit packages, and then re-install them just in case they are needed.
Let’s uninstall them:

Culprits removed. Now bring them back with
yum install qpid-cpp-server qpid-cpp-client
and we’re done. Now yum update works fine again without any error messages.
A thousand thanks to you
thank you
Perfect solution. Thanks for the help.
