Hello @shrinath.shanbhag!
Also, another user had the same ENOENT error in this post: Nucleus ENOENT: no such file or directory, open ‘…/launcher.toml’ Error
Here is the solution posted in that thread. Try this out and let me know if it helps solve your problem!
- Uninstall Cache
- Download Nucleus from NVIDIA Isaac Sim - Getting Started | NVIDIA Developer
- Try to install Nucleus on Omniverse launcher then it’s download setup folder in “~/.local/share/ov/pkg/nucleus-workstation-2021.2.4/”
- Extract and paste on “~/.local/share/ov/pkg/nucleus-workstation-2021.2.4/” the downloaded nucleus zip (step 2) file except setup folder.
- And try to install nucleus again.
- Reinstall Cache.
