You are troubleshooting your yum installation, getting the missing libraries

root@linux:~ # yum whatprovides
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named gzip

Please install a package which provides this module, or
verify that the module is installed correctly.

current version of Python, which is:
2.4.3 (#1, Aug 29 2011, 10:55:55)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)]

If you cannot solve this problem yourself, please go to

If you see a different module, try to install all python libraries

If you try to install or update a package and the following error message appears

root@suselinux10sp2:~ # rpm -Uvh supportutils-1.20-81.1.noarch.rpm
warning: supportutils-1.20-81.1.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 823559f0
error: Failed dependencies:
rpmlib(PayloadIsLzma) <= 4.4.6-1 is needed by supportutils-1.20-81.1.noarch

You need to verify if the compression method is supported by rpm.

root@suselinux10sp2:~ # rpm —showrc | grep Payload
rpmlib(PayloadIsBzip2) = 3.0.5-1
rpmlib(PayloadFilesHavePrefix) = 4.0-1

In this machine, only bzip2 is supported. One work-around is to update the rpm package before trying to install/upgrade the package where the error message appeared.

rpm error: failed to stat /media: Input/output error

I had a system where the rpm command was very slow after I was trying to upgrade a package

root@rhel5:~ # rpm -Uvh /tmp/kexec-tools-1.102pre-154.el5.x86_64.rpm
error: failed to stat /media: Input/output error
Preparing… ########################################### [100%]

########################################### [100%]

The filesystem /media is a NFS share. The server that was hosting the NFS was down and the rpm command was slow because it tried to stat the filesystem.
