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

   Could not load module /opt/freeware/lib/python2.7/site-packages/pycurl.so.
        Dependent module /opt/freeware/lib/libcrypto.a(libcrypto.so) could not be loaded.
        Member libcrypto.so is not found in archive
Could not load module /opt/freeware/lib/python2.7/site-packages/pycurl.so.
        Dependent module /opt/freeware/lib/python2.7/site-packages/pycurl.so could not be loaded.

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:
2.7.12 (default, Feb 20 2017, 03:58:51) [C]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

What is wrong?

Best regards,

Hello Andreas,

Is expat installed? If not install it and try again.

Here's a link to AIX Toolbox build: ftp://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/expat/

I have installed the latest versio of expat.

expat-2.2.0-1.ppc

Thanks and regards,

Looks like the issue is due to older version of openssl on your system. 

'yum update' updates the packages those are built with newer openssl and looks in your system you still have older openssl.

Please update to latest openssl as the new RPMs are compiled with latest openssl of AIX. 

You can find the latest openssl for AIX @ https://www-01.ibm.com/marketing/iwm/iwm/web/reg/pick.do?source=aixbp&lang=en_US

Thanks

I think you have installed openssl or/and curl rpms from other source. 

From the error message, i see "/opt/freeware/lib/python2.7/site-packages/pycurl.so" is linking to "/opt/freeware/lib/libcrypto.a(libcrypto.so)". That is not going to be the case with AIX toolbox curl. It will link to /usr/lib/libcrypto.a

Make sure python-pycurl rpm is from AIX toolbox and openssl filesets are installed properly. We won't provide rpms for openssl but one can download the filesets from AIX web download pack as mentioned by @sanket cbe53685-ee70-42e6-aed9-d174561da6e9 .​ And also make sure you ran "updtvpkg" command after installing the openssl filesets.

Sorry, but this wasn't the problem. I have installed curl, openssl, openldap and sudo from AIX Toolbox again. I had also to re-install sudo with an older version because of a dependency to openldap. the rpm package for openssl isn't available on https://www-03.ibm.com/systems/power/software/aix/linux/toolbox/alpha.html, so I have used the version from http://www.perzl.org/aix/index.php?n=Main.Openssl.

Then I have installed resp. updated the following packages from yum_bundle.tar with --force...

ca-certificates-2016.10.7-2.aix6.1.ppc.rpm
curl-7.52.1-1.aix6.1.ppc.rpm
db-4.8.24-3.aix6.1.ppc.rpm

python-2.7.10-1.aix6.1.ppc.rpm

python-pycurl-7.19.3-1.aix6.1.ppc.rpm

yum-3.4.3-5.aix6.1.noarch.rpm
yum-metadata-parser-1.1.4-2.aix6.1.ppc.rpm

...and after them yum was working again.

# yum check
check all

Then I have carried out a yum update again and I run in the same problem.

python-2.7.10-1.aix6.1.ppc.rpm

But on an other LPAR I have the following constallation of packages installed and yum is also working.

What is wrong with yum update or with the packages at AIX Toolbox?

However, if @Ayappan is reading this it's worth pointing out that the libcurl.so on the toolbox appears to have /opt/freeware/lib at the start of it's embedded library search PATH:

Summary     : A Python interface to libcurl
Description :
PycURL is a Python interface to libcurl. PycURL can be used to fetch
objects identified by a URL from a Python program, similar to the
urllib Python module. PycURL is mature, very fast, and supports a lot
of features.
#

Locating the offending openssl rpm and removing it resolves the problem (it's unclear where it actually came from on my machine, but removing it has so far not caused any problems as no other rpm is claiming to depend on it). After doing this yum works again:

# rpm -qf /opt/freeware/lib/libssl.so
openssl-1.0.1g-1.ppc
# rpm -e openssl-1.0.1g-1.ppc
#

Perhaps we should have a check at the start of yum.sh and abort if /opt/freeware/lib/libcrypto.so is present?
