Conda installation error

Hello

I am currently trying to install Qiime2 through conda, conda 25.1.0, on a linux based hpc cluster. I used the following command:

conda env create \
  --name qiime2-amplicon-2025.7 \
  --file https://raw.githubusercontent.com/qiime2/distributions/refs/heads/dev/2025.7/amplicon/released/qiime2-amplicon-ubuntu-latest-conda.yml

However I am returned with this error:

reparing transaction: done

Verifying transaction: done

Executing transaction: done

Channels:

- released

- conda-forge

- bioconda

- defaults

Platform: linux-64

Collecting package metadata (repodata.json): done

Solving environment: failed

LibMambaUnsatisfiableError: Encountered problems while solving:

- package gcc-13.4.0-h81444f0_6 requires gcc_impl_linux-64 13.4.0.*, but none of the providers can be installed

Could not solve for environment specs

The following packages are incompatible

├─ gcc =13 * is installable with the potential options

│ ├─ gcc 13.1.0 would require

│ │ └─ gcc_impl_linux-64 =13.1.0 *, which can be installed;

│ ├─ gcc 13.2.0 would require

│ │ └─ gcc_impl_linux-64 =13.2.0 *, which can be installed;

│ ├─ gcc 13.3.0 would require

│ │ └─ gcc_impl_linux-64 =13.3.0 *, which can be installed;

│ └─ gcc 13.4.0 would require

│ └─ gcc_impl_linux-64 =13.4.0 *, which can be installed;

└─ gcc_impl_linux-64 =15.1.0 * is not installable because it conflicts with any installable versions previously reported.

Is there a way to make these compatible or at least have a work around.

Hello @TylerRP171,

Can you try running conda clean --all then attempting to create the environment again?

No luck unfortunately. I have sent an email to those that run our farm hpc cluster to see if there is a work around for the package conflicts.

Hi @TylerRP171,
I am sorry to hear that this didn't work. Let us know what the HPC cluster says, maybe we can pass that info along to other users if its applicable. Thank you.
