[SOLVED] Cannot import Torvalds's GPG key

I cannnot import Linus Torvalds's GPG key by

gpg --search-keys ABAF11C65A2970B130ABE3C479BE3E4300411886

althought I can import Greg Kroah-Hartman's key by

gpg --search-keys 647F28654894E3BD457199BE38DBBDC86092693E

logs:

$ gpg --search-keys ABAF11C65A2970B130ABE3C479BE3E4300411886
gpg: data source: http://51.38.91.189:11371
(1)     Linus Torvalds <torvalds@kernel.org>
Linus Torvalds <torvalds@linux-foundation.org>
2048 bit RSA key 79BE3E4300411886, 作成: 2011-09-20
Keys 1-1 of 1 for "ABAF11C65A2970B130ABE3C479BE3E4300411886".  番号(s)、N)次、またはQ)中止を入力してください >1

And it hangs.

Re: [SOLVED] Cannot import Torvalds's GPG key

There is probably an idiot out there gloating about poisoning this key. The Web of Trust won't work anymore with this key, you could get a clean version from https://keys.openpgp.org/, though.

Re: [SOLVED] Cannot import Torvalds's GPG key

It did complete on this sytem but wastes a lot of cpu time.

gpg --search-keys ABAF11C65A2970B130ABE3C479BE3E4300411886
gpg: directory '/home/testuser/.gnupg' created
gpg: keybox '/home/testuser/.gnupg/pubring.kbx' created

As kernel.org provides WKD

gpg --locate-keys torvalds@kernel.org

Here is the mitigation against poisoned keys at work.

Thank you folks, gpg had successfully imported Torvalds's key while I was sleeping.

Re: [SOLVED] Cannot import Torvalds's GPG key

As a final note I'll add that the kernel web of trust with trust paths to Linus lives in a git repository for now:

https://lore.kernel.org/lkml/2019083014 … .i7.local/

https://git.kernel.org/pub/scm/docs/kernel/pgpkeys.git
