Hi,

With a very simple Snakefile test case like this:

rule test:
    shell:
         'echo "Hello world!"'

here is the output got with glpk-utils installed (sagemath requires it on
this system):

$ snakemake -j1
Building DAG of jobs...
Using shell: /bin/bash
Provided cores: 1 (use --cores to define parallelism)
Rules claiming more threads will be scaled down.
Job counts:
    count    jobs
    1    test
    1

Parameter(s) specified in the command line:

    success = scheduler.schedule()
  File "/usr/lib/python3/dist-packages/snakemake/scheduler.py", line 406,
in schedule
    else self.job_selector_ilp(needrun)
  File "/usr/lib/python3/dist-packages/snakemake/scheduler.py", line 624,
in job_selector_ilp
    prob.solve()

    status = solver.actualSolve(self, **kwargs)

actualSolve
    raise PulpSolverError("PuLP: Error while executing "+self.path)
pulp.solvers.PulpSolverError: PuLP: Error while executing glpsol

And here is the output once this package removed:

$ snakemake -j1

Hello world!

Complete log:
/home/patrice/tmp/toto/.snakemake/log/2021-03-22T182240.369114.snakemake.log

I do not know if there is a bug behind the scene and which package is
involved.

Thanks!
