This appears to be broken due to the new GPG 2.1 version that removes secring.gpg, so if you're using the latest version of GPG it won't work at all.

Attempting to verify a helm package with gpg 2.2.4 results in:

[debug] Created tunnel using local port: '65416'

[debug] SERVER: "127.0.0.1:65416"

[debug] Original chart version: ""
Error: failed to load keyring: open /Users/jaredallard/.gnupg/pubring.gpg: no such file or directory

Running ln -s ~/.gnupg/pubring.kbx ~/.gnupg/pubring.gpg results in:

[debug] SERVER: "127.0.0.1:49500"

So, all of gpg related functions appear to be broken with gpg 2.1+

lrvick · 2018-04-08T08:52:32Z

Able to reproduce here too. Smartcard support was not working until gpg 2x and signing is totally broken in gpg 2x which in turn means smartcard signing with helm is not currently possible at all.

This is a major blocker that prevents usage of helm at two organizations I manage.

Trying to hunt this down now

technosophos · 2018-09-26T19:58:21Z

Testing with older keyrings seems to work fine, so this does appear to be something caused by a newer GnuPG version. But I am still testing, so I may know more in a bit.

technosophos · 2018-09-27T01:39:06Z

Okay, in the process of testing, it appears that the GnuPG keyring format has changed. This is totally allowed by the OpenPGP spec, which does not require that a keyring be in a particular format.

If I run gpg --export --outfile newkeyring.gpg and then load that new keyring, it works fine, because that puts the keys in the format described by section 4.2 of the OpenPGP spec.

The relevant GnuPG announcement: https://gnupg.org/faq/whats-new-in-2.1.html#keybox

Update: Use --export-secret-keys to export the secret keys (signing), or --export to export your public keys (verifying).

technosophos · 2018-09-27T15:11:51Z

After taking a long look at the code, I actually really like what GnuPG did... but I don't have time to implement an undocumented file format. So for now, I'm going to suggest that we export to the binary entity-list format and continue using that.

If anyone feels like a fun challenge, here's the code for the new file format. It would be awesome to have this as a stand-alone Go library.

https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git;a=blob;f=kbx/keybox-file.c;h=046e3212304278c6232777b0a0c080656517ff5d;hb=refs/heads/master

jaredallard · 2018-09-28T18:59:16Z

I don't feel that this should be closed @technosophos. Converting from one format to the other isn't really a valid workaround and introduces differences between the two rings. Sure, the documentation is useful, but this is still an out of the box issues for most (if not all) Linux users.

technosophos · 2018-09-28T20:03:25Z

What do you suggest the fix is?

jmataa · 2018-12-20T15:47:22Z

FYI, I think there has been an openpgp issue raised here for the new format:
golang/go#29082

technosophos · 2018-12-20T16:04:19Z

I have it on my todo list to write a keybox library, but it's nowhere near a high priority for me. So if they make any progress I will be very, very happy.

ghost · 2020-05-19T18:29:55Z

I have got this error > Error: openpgp: invalid data: tag byte does not have MSB set

I able to solved it using the below steps
Execute: gpg --export-secret-keys >~/.gnupg/secring.gpg

Explanation: the GnuPG v2 store your secret keyring using a new format kbx on the default location ~/.gnupg/pubring.kbx. Please use the following command to convert your keyring to the legacy gpg format:

The output:
gpg: starting migration from earlier GnuPG versions
gpg: porting secret keys from '/Users/narendranathreddy/.gnupg/secring.gpg' to gpg-agent
gpg: migration succeeded

and upon checking ~/.gnupg/secring.gpg is exist

we can use secring.gpg to sign the packages using below command
helm package --sign --key 'Narendranath Reddy' --keyring ~/.gnupg/secring.gpg sample-app

Output:
Successfully packaged chart and saved it to: /Volumes/REDLAB/Projects/books/chapter-5/sample-app-0.1.0.tgz

4mig4 · 2021-09-02T03:30:16Z

I still have this problem, I do not think this issue should be closed at all until resolved.

jedcunningham · 2022-01-10T23:52:52Z

After hitting this trying to use a key on a smartcard (yubikey), I found that the Helm GnuPG plugin works as expected! It generates a provenience file and helm verify is happy too (if you have a GnuPG v1 keyring to run it against).

vineetguptadev · 2023-01-19T17:22:33Z

I just want to reiterate that this is still an issue and I am having a hard time fixing this.

echo "$HELM_KEY_PASSPHRASE" | gpg --batch --yes  --passphrase-fd 0 ~/.gnupg/secring.gpg

Flannigan · 2023-03-09T22:41:57Z

@vineetguptadev I was just able to resolve a similar error, albeit on the helm verify side, by converting my keyring to the old format as outlined in the current helm docs:

$ gpg --export >~/.gnupg/pubring.gpg
$ gpg --export-secret-keys >~/.gnupg/secring.gpg

Have you tried that and / or did it work?
