Conda is a powerful package manager widely used in the data science and scientific computing communities for managing software dependencies. However, when working with Conda, you might occasionally encounter an error message that reads: “Failed with repodata from current_repodata.json, will retry with the next repodata source.” This message can be puzzling, but it’s a common issue with a straightforward solution.
In this article, we’ll explore the causes of this error message and guide you through the steps to effectively resolve it.

ToggleUnderstanding the “Failed with repodata from current_repodata.json” Error
This error occurs when Conda is unable to retrieve the necessary package metadata, or “repodata,” from the current repodata.json file. Conda uses repodata files to understand the available packages, their versions, and dependencies.
When you encounter this error, it often means there is an issue with the current repodata source you’re using, and Conda will attempt to fetch the repodata from the next available source.
Resolving the Error
To resolve the “Failed with repodata from current_repodata.json” error, follow these steps:
1. Check Your Internet Connection
Ensure that your internet connection is stable and active. A poor or interrupted connection can lead to issues with fetching package information. Try loading a webpage or running a simple ping
command to verify your connection.
2. Verify Conda Channels
Conda relies on channels to find and install packages. If you’re encountering this error, it’s possible that the current channel you’re using has issues with its repodata. To address this, consider switching to a different channel.
You can add or switch channels using the following commands:
conda config --add channels conda-forge
This command adds the popular Conda-Forge channel as an additional source for packages. You can replace conda-forge
with any other channel you prefer.
3. Update Conda
Ensure that you’re using the latest version of Conda, as newer versions often contain bug fixes and improved error handling. Update Conda using the following command:
conda update conda
4. Clear the Conda Cache
Sometimes, the local Conda cache can become corrupted, causing issues with fetching repodata. Clear the cache by running:
conda clean -a
This command removes cached files and package metadata. Be aware that this might increase the time it takes to fetch packages during future installations, as Conda will need to redownload package metadata.
5. Retry the Installation
Once you’ve performed the steps above, retry your Conda operation. If it was an installation or update command that initially triggered the error, try running it again.
Wrapping Up
The “Failed with repodata from current_repodata.json” error in Conda can be resolved by ensuring a stable internet connection, verifying your Conda channels, keeping Conda updated, and clearing the cache. With these steps, you’ll be able to maintain a smooth and efficient software management process when working with Conda for data science, scientific computing, or any other use case.
