Our caching server gives a consistent failure for one package. It exists in the store and 'guix gc checks' pass.
guix substitute: error: download from 'http://guix.genenetwork.org:8080/nar/sqd3q1xq5fsbga00bwhghi9shi7xdaac-gtk+-3.18.2' failed: 404, "Not Found" Now I want to purge it without running a full gc. Next reinstall it and see if it gets fixed. What is the suggested method for fully purging a package from the store? Pj.
