   I read somewhere that someone got the correct library from an Anaconda install.
   I confirmed by using the following instructions.

   wget https://repo.anaconda.com/archive/Anaconda3-2019.07-Linux-x86_64.sh
   sh Anaconda3-2019.07-Linux-x86_64.sh
   cp anaconda3/lib/libstdc++.so.6.0.26 /usr/lib64
   rm /usr/lib64/libstdc++.so.6
   ln -s /usr/lib64/libstdc++.so.6.0.26 /usr/lib64/libstdc++.so.6

    We already set a minimum GLIBC that you'll require so this is closed off. If you're still getting these errors, upgrade to CentOS 8.

    Or use Docker

    This worked for me on Centos 7. The essential steps were

    cd /usr/local/lib64
    sudo wget http://www.vuln.cn/wp-content/uploads/2019/08/libstdc.so_.6.0.26.zip
    sudo unzip libstdc.so_.6.0.26.zip
    sudo cp libstdc++.so.6.0.26 /usr/lib64
    cd /usr/lib64
    ls -l | grep libstdc++ (just to check the symlink)
    sudo rm libstdc++.so.6
    sudo ln -s libstdc++.so.6.0.26 libstdc++.so.6

    This is still the fix in 2024.

    centOS 系统可以在 https://www.jianshu.com/p/050b2b777b9d 上进行引用，它是 vlaid，我检查了一下。

    这在 Centos 7 上对我有用。基本步骤是

    cd /usr/local/lib64 sudo wget http://www.vuln.cn/wp-content/uploads/2019/08/libstdc.so_.6.0.26.zip sudo unzip libstdc.so_.6.0.26.zip sudo cp libstdc++.so.6.0.26 /usr/lib64 cd /usr/lib64 ls -l |grep libstdc++（只是为了检查符号链接） sudo rm libstdc++.so.6 sudo ln -s libstdc++.so.6.0.26 libstdc++.so.6

    Perfect solution

    Just install the new libstdc++.so.6 version

    You can get it with: curl -o "/usr/lib/x86_64-linux-gnu/libstdc++.so.6" "redacted"

    This website is a scam. Do not run this line!
