Yum says I need Mozilla. It's already there!

Scientific Linux 4.3, a clone of Red Hat Enterprise, very similar to CentOS. It runs yum every night for updates. It's been working fine for months, but a few days ago it began failing in an odd way. The error messages look like this:

Error: Missing Dependency: mozilla-nss = 37:1.7.13-1.4.1 is needed by package mozilla-nss-devel

Yet it's already there:

Quote:

$ rpm -q mozilla
mozilla-1.7.13-1.4.1.i386

There are 4 machines. Two of them have mozilla installed, and they both do this. The other two are updating themselves properly. What's going on?

Try running "yum clean all". I have seen some strange issues with yum on occasion on my CentOS systems. When this happens I run this command which seems to clean up the error. I think it causes yum to rebuild it's dependency database.

Thanks for the idea. Unfortunately it did't change anything.

I did some more research. I went through the list of packages returned by "yum check-update", updating by hand the ones which didn't trigger the errors. At the end I was left with only two: devhelp and devhelp-devel. Updating either of them alone or in combination produces the errors mentioned above.

Upon examining the errors in more detail, I find some strange things.

It seems to want Mozilla 1.8, which doesn't exist in the repository. Then it wants seamonkey, which isn't installed. I'm puzzled.

Just for completeness:

mozilla-js-debugger-1.7.13-1.4.1.i386

It's all there.

Someone in another forum gave me the answer I needed. Here it is.

Quote:

Try

yum upgrade

The upstream vendor is replacing mozilla with seamonkey, so the new seamonkey obsoletes mozilla while it also provides it. Yum update does know know about the "obsoletes" but yum upgrade does.

That did the job. Mozilla was replaced by seamonkey, and everything worked OK after that.
