In reply to mmonnin's message of 7 Feb 2026:

I have not had those errors but another

glibc version 2.36 is needed.

lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found

How to install glibc_2.36? I can't find it for Linux Mint.
Libc.so.6 is not in the Mint repository.
I tried:

sudo apt install libc6

and it replied

libc6 is already the newest version (2.35-0ubuntu3.13).

In reply to mmonnin's message of 7 Feb 2026:

Update Mint to a newer version to whatever version is based off of Ubuntu 24

LM 22.3 runs both CPU and GPU WUs.
CPU needs about 1 GB RAM per WU and GPU needs about 1.5 GB RAM per WU.

All my Linux GPU tasks version 3.57 finish within seconds but STDERR contains the following line:

[BOINC] Error: CUDA_ERROR_NO_BINARY_FOR_GPU: no kernel image is available for execution on the device

Does anybody know if I can do anything about it? Got Mint 22.3.

You need the latest Pytorch with CUDA 12.8 support.
Run pip install --pre --upgrade torch torchvision --index-url https://download.pytorch.org/whl/nightly/cu128 in a terminal.

I encountered following error in WU:

<core_client_version>8.0.2</core_client_version>
