Hi @climbfuji! I noticed that the following package(s) don't yet have maintainers:

• py-protobuf

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("climbfuji")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame py-protobuf

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.

@spackbot fix style

Let me see if I can fix that for you!

I was able to run spack style --fix for you!

I've updated the branch with style fixes.

I've removed all changes related to PYTHONPATH or CYLC_PYTHONPATH, leaving the logic as is for now (working with the cylc developers in their repository on a solution). I added the corresponding versions and dependencies of other cylc packages. This PR is now ready for review.

@teaguesterling @LydDeb @scheibelp Gentle reminder about this PR, thanks!

@spackbot run pipeline

I've started that pipeline for you!
