This is the first CI with the error https://github.com/ami-iit/bipedal-locomotion-framework/actions/runs/13689823797 actually 13 hours ago

This is the difference between working CI https://github.com/ami-iit/bipedal-locomotion-framework/actions/runs/13667162197/job/38210583745 and not working CI https://github.com/ami-iit/bipedal-locomotion-framework/actions/runs/13689823797/job/38280885996#step:10:124

The fix appeared the first time on https://github.com/gabime/spdlog/releases/tag/v1.15.1
But in our case we have

    spdlog-1.14.1              |       hed91bc2_1         191 KB  conda-forge

Let's see if #945 fixes the problem

Forcing spdlog to be at least v1.15.1` makes the environment not solvable 😭

LibMambaUnsatisfiableError: Encountered problems while solving:
  - package ros-humble-rclcpp-16.0.2-py310h7c61026_2 requires ros-humble-rcl, but none of the providers can be installed

Could not solve for environment specs
The following packages are incompatible
├─ ros-humble-rclcpp is installable and it requires
│  └─ ros-humble-rcl, which requires
│     └─ ros-humble-rcl-logging-spdlog with the potential options
│        ├─ ros-humble-rcl-logging-spdlog 2.3.1 would require
│        │  └─ spdlog >=1.11.0,<1.12.0a0 , which can be installed;
│        ├─ ros-humble-rcl-logging-spdlog 2.3.1 would require
│        │  └─ spdlog >=1.12.0,<1.13.0a0 , which can be installed;
│        └─ ros-humble-rcl-logging-spdlog 2.3.1 would require
│           └─ spdlog >=1.14.1,<1.15.0a0 , which can be installed;
└─ spdlog >=1.15.1  is not installable because it conflicts with any installable versions previously reported.

See my comment in #945 (comment) . If you like the change from Humble to Jazzy, I can do it in the same PR. Otherwise the alternative is to do a rebuild of ros-humble, that is doable but takes some time.
