Just a brief post to note an issue that may come up for others and seems worth documenting in that eventuality:

In attempting to do a new local build of the Stack (using the method of [https://pipelines.lsst.io/install/lsstsw.html](https://pipelines.lsst.io/install/lsstsw.html) ), I kept getting errors of the form:

```auto
CondaHTTPError: HTTP 404 Not Found
for url <http://research.majuric.org/conda/stable/osx-64/repodata.json>

```

which @jsick pointed out is a deprecated URL, but nothing in the deploy script was referencing the URL. Turned out it was referred to in a `.condarc` file in my home dir which contained:

```auto
channels:
  - http://research.majuric.org/conda/stable
  - defaults

```

(and must have been left over from some ancient build attempt). I deleted this, and apart from a small hiccup with it hanging up at one point on `afwdata` for a while (which i then just added to the `etc/exclusions.txt` file, since i plan to run just some code from pipe\_tasks right now, and then restarted the build), it cranked all the way through, and built successfully.

[H/t to @jmeyers314 for the suggestion!]
