Miniconda permission errors

Since earlier today using miniconda to install any libraries which attempt to write an entrypoint script into the miniconda env directory raises Permission Denied errors and causes the build to fail. An example is this build on the public hvPlot repo ( or this build on the bokeh repo (

    ERROR An error occurred while installing package 'conda-forge::ipykernel-4.10.0-py27_1'.
    IOError(13, 'Permission denied')
    Attempting to roll back.
    [Errno 13] Permission denied: u'C:\\Miniconda-x64\\envs\\test\\Scripts\\jupyter-kernel.exe'

The hvPlot build is the result of rerunning a previous build, which passed just a few days earlier (i.e. nothing has changed about the environment). I suspect some mistake was made rolling out an image with broken permissions in the Miniconda directory.

    Hi Philipp,

    Build images were not updated during this period. You can always check is here. Also I would recommend to subscribe to technical updates here.

    Probably, cause of your problem is a different build of jupyter_client-5.2.4 being downloaded. It is py_0 for successful build and py_1 for failed.

    It's looking like this is in fact an issue in conda itself, further discussion can happen here:
