Looks like the last PR check was run on Nov 14, 2025. I'm curious if opening a PR with no changes in it right now would fail with the same error I'm getting.
Here is the terminal output containing the error. I'm on Mac OS 26.3.1, Apple M5 chip. A colleague of mine is seeing similar output on Linux today as well.
(base) ➜ MARINE git:(main) mamba create -n marine_environment python=3.10 -y

warning libmamba The specification of the environment does not seem solvable in your current setup.
warning libmamba For instance, packages from different channels might be specified,
warning libmamba whilst your current configuration might not allow their resolution.
warning libmamba
warning libmamba If it is the case, you need to either:
warning libmamba - adapt the channel ordering (e.g. by reordering the `-c` flags in your command line)
warning libmamba - use the flexible channel priority (e.g. using `--channel-priority flexible` in your command line)
warning libmamba

critical libmamba Could not solve for environment specs
Looks like the last PR check was run on Nov 14, 2025. I'm curious if opening a PR with no changes in it right now would fail with the same error I'm getting.
Here is the terminal output containing the error. I'm on Mac OS 26.3.1, Apple M5 chip. A colleague of mine is seeing similar output on Linux today as well.
