Hi everyone, I’m getting ready for the LSST@Europe2 tutorials in Belgrade next week, but am encountering a permissions problem when trying to set up the science-pipeline stack inside Conda. Specifically, I have installed Miniconda (Python 2.7) and am working through the setup commands listed in Section 2 on page [https://pipelines.lsst.io/install/conda.html](https://pipelines.lsst.io/install/conda.html). However, having run: > % conda config --add channels [http://conda.lsst.codes/stack](http://conda.lsst.codes/stack) —apparently successfully, I encounter an error with the subsequent command: > % conda create --name lsst python=2 > Fetching package metadata …Error: HTTPError: 403 Client Error: Forbidden for url: [http://conda.lsst.codes/stack/win-64/repodata.json.bz2:](http://conda.lsst.codes/stack/win-64/repodata.json.bz2:) [http://conda.lsst.codes/stack/win-64/](http://conda.lsst.codes/stack/win-64/) I’ve tried the install on both a Xubuntu and a Windows 8 machine with exactly the same result. Any advice as to what I am doing wrong would be much appreciated! Thanks in advance, George. ---

Could you post the`.condarc` from the xubuntu machine? It is really strange that it thinks it’s arch is `win-64`. ---

Sorry, the error I logged in my previous post was from the Windows 8 attempt. I simply meant that I had also tried from a Xubuntu (32-bit) installation and got the same ‘Forbidden URL …’ error. Thanks, George. ---

For completeness, on Xubuntu I get: $ conda create --name lsst python=2Fetching package metadata …Error: HTTPError: 403 Client Error: Forbidden for url: [http://conda.lsst.codes/stack/linux-32/repodata.json.bz2:](http://conda.lsst.codes/stack/linux-32/repodata.json.bz2:) [http://conda.lsst.codes/stack/linux-32/](http://conda.lsst.codes/stack/linux-32/) ---

Unfortunately, we don’t support 32-bit architectures any more. (This means my desktop doesn’t run the stack…) ---

Hi K-T, Thanks. This seems to explain why I can’t install the software stack on my 32-bit Ubuntu image, though should I be able to install on my 64-bit Windows laptop? Thanks again, George. ---

> [@george\_beckett](#): > > This seems to explain why I can’t install the software stack on my 32-bit Ubuntu image, though should I be able to install on my 64-bit Windows laptop? I’m afraid not; [this thread](http://www.rubin.community/t/lsst-stack-on-ubuntu-linux-on-windows/666) discusses the closest anyone has gotten to running the stack on Windows, and even with a new embedded Linux feature in a prerelease version of Windows 10, it doesn’t quite work. If you can create a 64-bit Ubuntu image, that should work fine (though I’d recommend 14.04 rather than the latest Ubuntu LTS release, just because we’ve had more people try that out). ---

Hi Jim, Okay, thanks. I’ll see if I can get a 64-bit Ubuntu VM, though might stress the hotel Wi-Fi! I’ll let you know how I get on, George. ---

One more note on this: the stack can require a fair amount of memory to build (we’d very much like to reduce this, but we’re not there yet), so it’d definitely be a good idea to use a binary install (either Conda or CernVM FS) if your VM is limited in that regard (obviously, that’ll be faster too). ---

Hi Jim (and everyone), Thanks. I successfully deployed the pipeline software on a 64-bit Linux system and ran the tutorials. Thanks for your help, George.
