Description Gopikannan Ellappan 2013-11-12 11:38:00 EST
Description of problem:

I'm trying to do createrepo via yum, i'm getting the below error,

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

   /usr/lib64/libcurl.so.4: undefined symbol: libssh2_scp_send64

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:
2.6.6 (r266:84292, May  1 2012, 13:52:17)
[GCC 4.4.6 20110731 (Red Hat 4.4.6-3)]

If you cannot solve this problem yourself, please go to
the yum faq at:

root@node1> cat redhat-release

How reproducible:


Expected results:

Please tell me how to avoid this error, Is it something I should upgrade here or something is corrupted.

Additional info:

I'm getting this error and its reproducible in my machine many times.
But my colleague informed me that, he didn't face any issues and he has done the same steps what I've done now.

Please let me know if you need any other details.
Comment 1 Kamil Dudka 2013-11-12 12:00:11 EST
Please provide the output of the following command:

rpm -q libcurl --requires | grep ssh
Comment 2 Gopikannan Ellappan 2013-11-12 12:07:31 EST
root@node1> rpm -q libcurl --requires |grep ssh
libssh2(x86-64) >= 1.4.2

I got it, Now I need to install 1.4.2 version of libssh2.

I will try this and let you know the result.  Thank you !
Comment 3 Kamil Dudka 2013-11-12 12:16:30 EST
Your system apparently suffers from broken RPM dependencies.  You have installed libcurl, which requires libssh2(x86-64) >= 1.4.2 despite you have no such package installed on your system.  How did you upgrade libcurl?
Comment 4 Gopikannan Ellappan 2013-11-12 12:19:30 EST
here we have the older version of libssh2.


So I should update, correct ?
Comment 5 Kamil Dudka 2013-11-12 12:24:29 EST
Yes.  But I do not understand how you installed libcurl-7.19.7-37.el6_4.x86_64 without installing a new enough version of libssh2 first.  Neither yum, nor rpm would allow it by default.
Comment 6 Gopikannan Ellappan 2013-11-12 12:47:31 EST
Even I'm not sure, how it got installed since this is the first time I'm using this machine..!!
Anyways - my issue got solved. 

Thanks for your quick help and I will let you know if I get any updates from my colleagues abt the installation.
Comment 8 Kamil Dudka 2013-11-12 15:29:03 EST
The libcurl package correctly requires a new enough version of libssh2 in order to prevent the above reported broken linkage.  For some reason, the packages installed on the system did not satisfy the dependency.  There is nothing to be fixed in curl or libssh2 packages, therefore I am closing this bug.
