Solving Ubuntu 18 nixpkgs conda Relocation Error: libc.so.6 symbol _dl_exception_create, version GLIBC_PRIVATE ld-linux-x86-64.so.2 Link Time Reference

Solving Ubuntu 18 nixpkgs conda Relocation Error: libc.so.6 symbol _dl_exception_create, version GLIBC_PRIVATE ld-linux-x86-64.so.2 Link Time Reference

When working with Ubuntu 18, nixpkgs, and conda, you may encounter a relocation error that involves libc.so.6 symbol _dl_exception_create, version GLIBC_PRIVATE ld-linux-x86-64.so.2 link time reference. This error can be a roadblock for data scientists who rely on these tools for their work. In this blog post, we’ll guide you through the steps to resolve this issue.

Understanding the Error

Before we dive into the solution, let’s understand the error. The error message indicates a problem with the dynamic linker/loader ld-linux-x86-64.so.2 and the GNU C Library (glibc). The symbol _dl_exception_create is a private symbol in glibc, which means it’s not intended for use outside of the library. This error typically arises when there’s a mismatch between the versions of glibc used to compile and run a program.

Step 1: Identifying the Problem

First, let’s identify the version of glibc that your system is using. You can do this by running the following command in your terminal:

ldd --version

This command will output the version of glibc that your system is currently using. If the version is not compatible with the one required by your program, you’ll need to update it.

Step 2: Updating glibc

To update glibc, you can use the following commands:

sudo apt-get update
sudo apt-get upgrade libc6

These commands will update your system’s package lists and upgrade the glibc package to the latest version.

Step 3: Verifying the Update

After updating, you can verify that the update was successful by running the ldd --version command again. If the version number has increased, the update was successful.

Step 4: Reinstalling nixpkgs and conda

Now that you’ve updated glibc, you’ll need to reinstall nixpkgs and conda. This is because these packages may have been compiled with the old version of glibc, and they need to be recompiled with the new version.

To reinstall nixpkgs, you can use the following command:

nix-env -i nixpkgs

To reinstall conda, you can use the following command:

conda install --force-reinstall conda

Step 5: Verifying the Solution

Finally, you can verify that the solution worked by running your program again. If the relocation error no longer appears, you’ve successfully resolved the issue.

Conclusion

The relocation error involving libc.so.6 symbol _dl_exception_create, version GLIBC_PRIVATE ld-linux-x86-64.so.2 link time reference can be a frustrating issue for data scientists working with Ubuntu 18, nixpkgs, and conda. However, by understanding the error and following the steps outlined in this blog post, you can resolve the issue and get back to your work.

Remember, the key to resolving this error is ensuring that your system’s version of glibc is compatible with the versions required by your programs. By keeping your system up to date and reinstalling packages as necessary, you can avoid this error and similar issues in the future.
