[SOLVED] Problem with the rpm libraries when trying to update

[dulkancellin]

Hello,

I made my last update on February 3. Now I realize that something must have happened because yum doesn't work.

[pablo@pampas ~]$ uname -a
Linux pampas 3.2.2-1.fc16.i686 #1 SMP Thu Jan 26 03:38:31 UTC 2012 i686 i686 i386 GNU/Linux

[pablo@pampas ~]$ yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
librpm.so.2: cannot dynamically load executable
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:
2.7.2 (default, Oct 27 2011, 01:36:46)
[GCC 4.6.1 20111003 (Red Hat 4.6.1-10)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq

I tried to reinstall yum using rpm, but
[pablo@pampas ~]$ rpm
rpm: error while loading shared libraries: librpm.so.2: cannot dynamically load executable

[pablo@pampas ~]$ ldd /bin/rpm
/bin/rpm: error while loading shared libraries: librpm.so.2: cannot dynamically load executable

However, librpm.so.2 seems to be present
[pablo@pampas ~]$ ls -ls /usr/lib/librpm*
0 lrwxrwxrwx. 1 root root 20 Feb 1 13:14 /usr/lib/librpmbuild.so.2 -> librpmbuild.so.2.0.1

312 -rwxr-xr-x. 1 root root 315500 Jan 24 19:26 /usr/lib/librpm.so.2.0.2

I don't know what have happened. I need to update, but I am afraid that the only way is reinstalling
yum or rpm from source code. I wish to avoid that. Can anyone help me out?

Thanks.

What does ldd -v say?

[dulkancellin]

Hi amturnip,

ldd -v gives the same output as ldd alone.

[pablo@pampas ~]$ ldd -v /bin/rpm
/bin/rpm: error while loading shared libraries: librpm.so.2: cannot dynamically load executable

Somehow librpm.so.2 got corrupted.
I don't know if it is the proper way, but this is how I fixed the problem.

From http://rpm.phone.net, I downlowded rpm-libs-4.9.1.2-5.fc16.i686.rpm
to extract a copy of librpm.so.2.0.2 in my home directory.

Then,
[root@pampas pablo]# rm -f /usr/lib/librpm.so.2*
[root@pampas pablo]# mv ~/librpm.so.2.0.2 /usr/lib
[root@pampas pablo]# ln -s librpm.so.2.0.2 librpm.so.2
[root@pampas pablo]# ldconfig -v | grep librpm.so.2
librpm.so.2 -> librpm.so.2.0.2

Now both rpm and yum work fine
