Hi, I have been running for the past few days without any problems before hitting this error. I am running the jun-13 node/farmer on Linux. Can someone tell me how to fix this?

What occurs if you update to the latest snapshot?

When I tried to run the latest version (June 18), I got the following error. Please advise on what to do. Thanks.

./subspace-node-ubuntu-x86_64-gemini-1b-2022-jun-18: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory

Answer sourced from - Farming with the CLI | Subspace Labs Documentation in the Linux section

There are two packages that are typically already installed, but might be missing on your machine.

If you see this error:

error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory

Make sure to install ocl-icd-libopencl1 library with sudo apt-get install ocl-icd-libopencl1.

If you see this error:

error while loading shared libraries: libgomp.so.1: cannot open shared object file: No such file or directory

Make sure to install libgomp1 library with sudo apt-get install libgomp1.

I did get through installing the missing file but now I have the following error; I believe this is the same error I got in the beginning.
