Error Updating Ubuntu WSL: Can't link /usr/lib/wsl/lib/libnvoptix\_loader.so.1 libnvoptix.so.1
When trying to update or install packages using sudo apt in Ubuntu WSL, you might encounter the following error:
/sbin/ldconfig.real: Can't link /usr/lib/wsl/lib/libnvoptix\_loader.so.1 libnvoptix.so.1
Context
This error occurs due to a missing library required for NVIDIA CUDA toolkit inside the Ubuntu WSL environment. WSL (Windows Subsystem for Linux) is a compatibility layer for running Linux binary executables natively on Windows 10. This issue can impact developers working with GPU-accelerated applications and libraries within the Ubuntu WSL environment.
Resolving the Issue
To resolve this issue, you need to create a symbolic link to the missing library inside the WSL environment. Follow the steps below to create the link:
-
Open the Windows command prompt or PowerShell as an administrator.
-
Navigate to the WSL installation directory:
cd C:\Users\%USERNAME%\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs -
Create the symbolic link:
sudo ln -s /mnt/c/Windows/System32/nvoptix.so.11.0.0 /usr/lib/wsl/lib/libnvoptix.so.1
