Tag: bad-distribution-in-changes-file Severity: error Check: fields/distribution Explanation: You've specified an unknown target distribution for your upload in the debian/changelog file. It is possible that you are uploading for a different distribution than the one Lintian is checking for. In that case, passing --profile $VENDOR may fix this warning. . Note that the distributions non-free and contrib are no longer valid. You'll have to use distribution unstable and Section: non-free/xxx or Section: contrib/xxx instead. See-Also: debian-policy 5.6.14
