Conda Installation Stuck: “Solving environment” Warning with “lib_mamba” Dependency Issue

What will you learn?

Discover how to troubleshoot and resolve the issue when a Conda installation becomes stuck at “Solving environment” due to a warning associated with the lib_mamba dependency.

Introduction to the Problem and Solution

Encountering an error mentioning lib_mamba during package installations using Conda typically signifies underlying package dependency conflicts or issues. To tackle this, it’s crucial to update or repair the Conda environment.

One effective approach involves updating Conda itself along with its dependencies. Additionally, addressing conflicting packages and adjusting solver rules can help overcome this specific error encountered during installation processes.


# Update Conda first
!conda update -n base -c defaults conda

# If updating fails, fix the solver rules
!conda install mamba -n base -c conda-forge

# Once mamba is installed, use it for package installations instead of conda

  • Updating Conda: Ensuring your Conda version is up-to-date by running conda update can aid in resolving dependency issues.
  • Installing Mamba: Mamba serves as an alternative package manager for Conda environments that may offer better dependency resolution capabilities than standard Conda. Incorporating Mamba into your workflow could resolve the lib_mamaba warning issue.
  • Executing Package Installations: After addressing solver rules or updating dependencies, proceed with your original package installations using Mamba instead of traditional Conda commands if necessary.
    How can I identify if my Conda installation is stuck due to lib_mamaba?

    The presence of the error message “Solving environment: / warning lib_mamaba Added empty dependency for problem type SOLVER_RULE_UPDATE” indicates this issue.
