Looks like cmake.org now expose a key to check tarballs: Cryptographic Hashescmake-3.4.0-rc1-SHA-256.txt cmake-3.4.0-rc1-SHA-256.txt.asc See: https://cmake.org/download/ Please import it (as debian/upstream/signing-key.asc)
Hi Mathieu, Unfortunately, upstream does not sign the archives themselves but a separate text file with SHA-256 hashes of all archives. AFAIK uscan cannot handle this type of signature automatically. Cheers Timo
