Error when retrieving "snakemake" package.

[cngo-github]

I keep getting this error on my pyshop server when I retrieve the "snakemake" package (e.g. pip3 install snakemake). My pip version is 10.0.1.

This is preventing me from building my docker images. It only recently started happening. What happened?

As you can see, the summary field for this package is longuer that expected.

Snakemake is a workflow management system that aims to reduce the complexity of creating workflows by providing a fast and comfortable execution environment, together with a clean and modern specification language in python style. Snakemake workflows are essentially Python scripts extended by declarative code to define rules. Rules describe how to create output files from input files.

https://bitbucket.org/snakemake/snakemake/src/7f3006da24affc63752c1fcb261152105fe160ec/setup.py?at=master&fileviewer=file-view-default#setup.py-31

The description should be "short" but there is no maximum size in the doc.

You should do an alter and pass the summary field as CIText under postgresql.
