CentOS yum segmentation fault (core dumped) solution

Today, when yum install or yum update, a segmentation fault (core dumped) is prompted, and then Termination of operation.

The code is as follows:

[root@lee ~]# yum -y update

Looking for articles about various prawns on Google still doesn’t help, so I have to check the errors carefully! First of all, I determined that it was not due to the Python version, because Python 2.7.4 was installed before.

The code is as follows:

# vim /usr/bin/yum

View the first line

The code is as follows:

#!/usr/bin/python2.6
import sys
try:
    import yum
except ImportError:
    print >> sys.stderr, """\
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
   %s
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:

""" % (sys.exc_value, sys.version)
    sys.exit(1)
sys.path.insert(0, '/usr/share/yum-cli')
try:
    import yummain
    yummain.user_main(sys.argv[1:], exit_code=True)
except KeyboardInterrupt, e:
    print >> sys.stderr, "\n\nExiting on user cancel."
    sys.exit(1)

The first line is

The code is as follows:

#!/usr/bin/python2.6

Check directly to see if there is a problem with Python2.6

The code is as follows:

[root@lee ~]# /usr/bin/python2.6 -V
Python 2.6.6

Correctly identify the version number, no problem. When yum clean all didn't help, I suddenly thought that there might be more things in the /etc/yum.repos.d/ directory?

The code is as follows:

[root@lee ~]# ls  /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-Media.repo  CentOS-Vault.repo  soluslabs.repo

I found that there is a soluslabs.repo in it, and the place where I reported errors with the yum command is a resource library. It seems that the problem lies here.

The code is as follows:

soluslabs                                    |  951 B     00:00     
soluslabs/primary                    |  11 kB     00:00     
段错误 (core dumped)

The previous line of the segfault is soluslabs, so I directly rm it

The code is as follows:

# rm -f /etc/yum.repos.d/soluslabs.repo

Then again Clean

The code is as follows:

# yum clean all

Okay, let’s go back to the familiar yum update

The code is as follows:

[root@lee ~]# yum -y update

Done, call it a day!

Another solution:

When using the yum command to install something or yum update, the following error is prompted:

The code is as follows:

[root@lee ~]# yum update
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile
 * base: mirrors.tuna.tsinghua.edu.cn
 * extras: mirrors.tuna.tsinghua.edu.cn
 * soluslabs: mirror.eu1.soluslabs.net
 * updates: mirrors.tuna.tsinghua.edu.cn
段错误 (core dumped)

Solution:

The code is as follows:

[root@lee ~]# rpm -q zlib zlib-devel
zlib-1.2.3-29.el6.x86_64
zlib-devel-1.2.3-29.el6.x86_64
[root@lee ~]# cp /usr/lib64/lib
Display all 1910 possibilities? (y or n)
[root@lee ~]# cp /usr/lib64/libz.so /usr/local/lib64/
[root@lee ~]# cd /usr/local/lib64/
[root@lee lib64]# ln -sf libz.so libz.so.1
[root@lee lib64]# yum clean all

My system is CentOS 64-bit. If it is 32-bit, copy it like this when assigning libz.so

The code is as follows:

[root@lee ~] cp /usr/lib/libz.so /usr/local/lib/

Then re-yum update.
