http://oxpedia.org/wiki/index.php?title=Open-Xchange_620_622_Update_Guide_for_CentOS5

But i got error when i try to do yum update:

---> Package open-xchange-themes-default.noarch 0:6.22.0-12_12.1 set to be updated

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.


What could be the issue here? How do i resolve this?

thanks!
