Hi, rrdtool package has not been updated for several years and according to ci.guix.gnu.org builds normally, but if you run:
./pre-inst-env guix build --no-substitutes --check --no-grafts rrdtool it outputs an error sha256 hash mismatch for /gnu/store/icyq4d3fsbbf2yw3dmg7cxgb05qzfd3q-rrdtool-1.7.2.tar.gz: expected hash: 1nsqra0g2nja19akmf9x5y9hhgc35ml3w9dcdz2ayz7zgvmzmm6d1 actual hash: 029r3h7l06m3sy9q0hr2krvinhzkqvyl14wj7qjck79bm7rdvp48 which looks strange to me. Maybe it's not, but I haven't figured out why? -- Best regards, Aleksandr Vityazev
