Conda install broken?

Hello, I have just been met with the following error across all of my anaconda distributions across various platforms when upgrading conda and despite several clean installs all attempts to install matminer via “conda install -c conda-forge matminer” result in the following message

(main36) C:\Users\mm049>conda install -c conda-forge matminer
Collecting package metadata (current_repodata.json): done

Is there a problem with the repository or is there a problem on my end?

Kind Regards

I haven’t seen this error before, but suspect that it could be an issue with your conda environments.

Could you try creating a fresh Python 3.7 environment (e.g., conda create --name matminer python==3.7.*) and then install matminer in that new environment?

That will help us figure out if the problem is particular to your environment.

Hey Michael, did you resolve your issue or is the conda install still broken for you?


Hi Ardunn, in the end I had to completly remove conda and then do a few force updates through apt before reinstalling it.

It’s fine now, probably an issue with my OS.

Hi I’ve had the issue again on another environment and have tried to resinstall anaconda from scratch and tried python 3.6 and 3.7 virtual envs to no avail, error is identical.

Hey MIchael,

Thanks for the update. This issue has been added to the github repo and we will work on fixing it. We’ll udpate this thread when things are fixed!
