Hi,
I found that it is python3-pulp that calls glpsol provided by glpk- utils: https://sources.debian.org/src/python-pulp/1.6.0+dfsg1-5/src/pulp/solvers.py/?hl=100#L100 It's strange that the python3-pulp package didn't at least suggest some of these tools because tracking my issue using apt rdepends didn't help that much. $ apt show python3-pulp Package: python3-pulp Version: 1.6.0+dfsg1-5 Priority: optional Section: python Source: python-pulp Maintainer: Debian OpenStack <team+openst...@tracker.debian.org> Installed-Size: 301 kB Depends: coinor-cbc, python3-pyparsing, python3:any Homepage: https://github.com/coin-or/pulp Tag: implemented-in::python $ apt rdepends glpk-utils glpk-utils Reverse Depends: Dépend: sagemath Should this be an issue on python3-pulp? Thanks, Patrice
