Tag: unnecessary-source-date-epoch-assignment Severity: info Check: debian/rules Explanation: There is an assignment to a SOURCE_DATE_EPOCH variable in the debian/rules file. . As of dpkg 1.18.8, this is no longer necessary as dpkg exports this variable if it is not already set. However, you can also include /usr/share/dpkg/pkg-info.mk or /usr/share/dpkg/default.mk to ensure it is exported. See-Also: https://reproducible-builds.org/specs/source-date-epoch/
