No, same issue: [torvalds@i7 linux]$ git fetch git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic tags/asm-generic-nommu From ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic * tag asm-generic-nommu -> FETCH_HEAD [torvalds@i7 linux]$ git verify-tag FETCH_HEAD gpg: Signature made Thu 16 May 2019 01:28:54 PM PDT gpg: using RSA key 60AB47FFC9095227 gpg: bad data signature from key 60AB47FFC9095227: Wrong key usage (0x00, 0x4) gpg: Can't check signature: Wrong key usage That's the same key you used previously. I think you have to do some gpg edit-key magic or something, and then the key need to be refreshed. But I really despise the usability of gpg, so what do I know? Linus
