I got this problem while creating a new conda environment, fixing the permission in ~/.conda did not help.
Make sure you can see the troublesome package in your base conda environment
If your conda is not owned by root user, you do not have to use sudo in the following commands
remove it
sudo bash -c "/opt/conda/bin/conda remove _libgcc_mutex"
then install it again
sudo bash -c "/opt/conda/bin/conda install _libgcc_mutex"
