Yum broken.. importing python module

senators24 · 02-24-2018, 08:48 PM

I've tried to figure out a solution to this on my own, I even reinstalled nghttp2. I can't seem to figure this out. I can't update anything using yum, also EasyApache 4 is failing to load in WHM, giving this error:

Quote:

YUM encountered errors outside of EasyApache 4. Log into the system via SSH to resolve them, or you can click the ‘Refresh’ button to rebuild the system‘s YUM cache.

This is what shows when I try and use yum to do anything:

Quote:

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

/lib64/libcurl.so.4: undefined symbol: nghttp2_session_callbacks_set_error_callback

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:
2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

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

I'm using CentOS 7.3
Also, yes I have checked their faq.

This is a shot in the dark, but what happens when you try

Code:

yum clean all

Same outcome as above.

I've even tried rebuilding the cache using

Code:

yum makecache

Another shot in the dark...

Code:

rm -rf /var/cache/yum

What happens then?

I assume it worked, no output was given when I gave that command. However, I'm still receiving the original error. Didn't seem to help.

It's something to do with nghttp2, can't figure out what for the life of me

My bad. I'm using CentOS 7.3

Bump up.. still haven't fixed this

The message is saying that there is a problem with /lib64/libcurl.so.4. What is the result of:

Code:

rpm -q libcurl

did you by chance CHANGE the default python version ?

the version in the cent base and update repos MUST!!! be used !!!!

now a second/third/ and so on versions can be installed in a side by side set up
-- this is the default on redhat systems

also 7.3 is NOT supported any longer
upgrade to 7.4 -- see the wiki on the centos web site

I never upgraded anything.. as far as I remember anyway. I just went to install some packages required by Magento and couldn't.

That libcurl package looks wrong. The libcurl provided by CentOS is libcurl-7.29.0-42.el7.x86_64.rpm (since you're running 7.3, there might be some other revision, but it'd definitely be 7.29.0-<n>, not 7.54).

You could try downloading the package from a CentOS mirror, then replace the one installed with the one from Cent0S.

You, sir, are a hero!! Removing 7.54 and installing 7.29 did the trick. Thank you!
