I had "googled" for a week and most of them suggested to do " rpm -vv --rebuilddb", but it did not work out for me. Please kindly help me out.

rpm --version : RPM version 4.4.2

The case:
Command: rpm -qa
Error:
rpmdb: /var/lib/rpm/Packages: unsupported hash version: 8
error: cannot open Packages index using db3 - Invalid argument (22)

Command: yum
Error:
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

/usr/lib/librpmdb-4.4.so: undefined symbol: poptSaveLong

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

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Dec 11 2006, 11:38:52)
[GCC 4.1.1 20061130 (Red Hat 4.1.1-43)]

If you cannot solve this problem yourself, please go to

Sorry for the bad english, but please help to solve out this problem, thx.

Did you 'rm -f /var/lib/rpm/__db*' before you 'rpm --rebuilddb'? Can you see in your up2date, yum or syslog what happened before this error started occuring? (If up2date, check this.) Were any of rpm, rpm-libs, popt, python, rpm-python or yum recently updated? Did other errors occur replated to RPM before this one? What does 'rpm -q rpm' say? And 'file /var/lib/rpm/*'? Can you (temporarily until you fix things) overcome the /usr/lib/librpmdb-4.4.so error by downloading a copy of the popt RPM, unpacking it ('cd /tmp; rpm2cpio /tmp/popt-.*.rpm | cpio -idmv') and copying the lib in place?

Sorry For the Late reply as we may be in different time zone

Yes i do run rm -f /var/lib/rpm/__db*
but i am quite sure that there is "__db*" file in the folder.

# up2date
-bash: up2date: command not found =[
I think this is the first time I ran yum , rpm on this machine.

Nope.

Nope according to what i can remember.

downloaded "popt-1.10.2-48.el5.i386.rpm" and followed your advice but
it did not seem like working. =[

Please tell us something about the general state of the machine then. Is this a fresh install? Was there another admin before you? When was the last time stuff got installed with RPM OK? Do you keep a backup schedule? How far back do they go?


If you manage multiple servers "remembering" gets tricky. Keeping a log of things helps. If you don't have a log, maybe check out whatever syslog/application logs you have instead?


Realise 'file' does not equal 'ls'? Besides it's darn odd all timestamps are similar.


I'm sorry but "did not seem like working" doesn't show me the steps you tried and any resulting (error) messages.

dear user you are not configure properly yum on your linux system
use yum of you linux version.It solve your problem.





thank for your question
