Hello?

There doesn't appear to be a CentOS specific forum;
so, I'm posting here instead.

Basically, I'm having an issue with up2date update
on CentOS 4 with the following message displayed
repeatedly proventing me progressing further in the
update process:

There was a package dependency problem. The message was:

Unresolvable chain of dependencies:
httpd-2.0.52-12.1.ent.centos4 requires apr >= 0.9.4-24.2

The following packages were added to your selection to satisfy dependencies:
Package Required by
-----------------------------

Please modify your package selections and try again.

I even tried with "yum update" but the error pops up along
the same line as above.

Does anyone have any suggestions?

Thanks.

Have you tried explicitly installing apr:
I had this problem and I think it may have fixed it for me

Hi tkedwards,

That works. Thanks.

It appears that explicitly installing it doesn't always work. From looking at posts on the Centos forums it appears that you should keep up with the latest ISO releases from CentOS as packages may be updated between releases (which correspond to Redhat's 'update' releases) but may not appear in the updates directory.

So for example between Centos 4.0 and 4.1 apr has gone from apr-0.9.4-24.1 to apr-0.9.4-24.3 but nowhere does apr appear in the updates directory for centos. So to get the updated apr you need to get the updated (ie. Centos4.1) ISO image, or point your yum at mirrror with 4.1 on it, and then do a yum update
