When trying selecting Check for updates in Manuscripts 10.0.7, a new update is automatically downloaded, but I am unable to extract the archive. Checking Console, it seems like there is something fishy going on with the signature on the update. This is what I see in Console:
16/11/15 1:37:19.247 PM Manuscripts: Sparkle: ===== Manuscripts =====
16/11/15 1:37:19.248 PM Manuscripts: Sparkle: DSA signature does not match. Data of the update file being checked is different than data that has been signed, or the public key and the private key are not from the same set.
16/11/15 1:37:19.248 PM Manuscripts: Sparkle: DSA signature validation failed. The update has a public DSA key and is signed with a DSA key, but the public key doesn't match the signature. The update will be rejected.
16/11/15 1:37:22.357 PM Manuscripts: Sparkle: Error: An error occurred while extracting the archive. Please try again later. The update is improperly signed. (URL (null))
