Hi Ned.,

What does rpm say? 'rpm -q --whatprovides /usr/lib64/libyaml-0.so.1'

This is what rpm reports back at that command:

[root@ops:~] #rpm -q --whatprovides /usr/lib64/libyaml-0.so.1 libyaml-0.1.2-3.el5.x86_64

...

Can someone please point me in the right direction for solving these problems?

These are not CentOS packages (python26-PyYAML and libyaml). I would suggest you ask on the appropriate list for whichever repository these packages were installed from (rpm -qi should tell you).

And here is what rpm -qi tells me:

[root@ops:~] #rpm -qi libyaml-0.1.2-3.el5.x86_64 Name : libyaml Relocations: (not relocatable) Version : 0.1.2 Vendor: Fedora Project < http://bugzilla.redhat.com/bugzilla%3E Release : 3.el5 Build Date: Tue Mar 3 13:53:12 2009 Install Date: Sat Nov 5 18:57:39 2011 Build Host: xenbuilder2.fedora.redhat.com Group : Development/Libraries Source RPM: libyaml-0.1.2-3.el5.src.rpm Size : 126347 License: MIT Signature : DSA/SHA1, Tue Mar 3 14:48:55 2009, Key ID 119cc036217521f6 Packager : Fedora Project http://bugzilla.redhat.com/bugzilla URL : http://pyyaml.org/ Summary : YAML 1.1 parser and emitter written in C Description : YAML is a data serialization format designed for human readability and interaction with scripting languages. LibYAML is a YAML parser and emitter written in C.

So thinking back it may have been a custom python repo that was used to install that.

So I guess I can take it from here!

Thanks Tim

Hey all,

I'm attempting to upgrade a Centos 5.9 machine to CentOS 5.10.

But when I try the yum update command I get this response:

--> Finished Dependency Resolution python26-PyYAML-3.08-5.el5.x86_64 from installed has depsolving problems --> Missing Dependency: libyaml-0.so.1()(64bit) is needed by package python26-PyYAML-3.08-5.el5.x86_64 (installed) --> Running transaction check ---> Package kernel.x86_64 0:2.6.18-164.15.1.el5.centos.plus set to be erased ---> Package kernel.x86_64 0:2.6.18-194.11.4.el5 set to be erased ---> Package kernel.x86_64 0:2.6.18-238.9.1.el5 set to be erased ---> Package kernel-devel.x86_64 0:2.6.18-308.4.1.el5 set to be erased --> Processing Dependency: libyaml-0.so.1()(64bit) for package: python26-PyYAML --> Finished Dependency Resolution python26-PyYAML-3.08-5.el5.x86_64 from installed has depsolving problems --> Missing Dependency: libyaml-0.so.1()(64bit) is needed by package python26-PyYAML-3.08-5.el5.x86_64 (installed) Error: Missing Dependency: libyaml-0.so.1()(64bit) is needed by package python26-PyYAML-3.08-5.el5.x86_64 (installed) 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 system claims that it can't find libyaml-0.so.1, however I can easily locate it:

[root@ops:~] #locate libyaml-0.so.1 /usr/lib64/libyaml-0.so.1 /usr/lib64/libyaml-0.so.1.1.0

What does rpm say? 'rpm -q --whatprovides /usr/lib64/libyaml-0.so.1'

...

This often helps to avoid broken dependencies:

yum --disablerepo=* --enablerepo=base --enablerepo=updates update

After that, a regular yum update.

Removing that libyaml package allowed me to upgrade!

Thanks for the tip!
