Cannot decrypt with GPG 2.2.5 and SOPS 3.0.0

It appears the utility is looking for a secret key in a file but my GPG installation (through macOS homebrew) uses the gpg-agent. I cannot decrypt files as demonstrated below.

$ sops --version
sops 3.0.0 (latest)

$ gpg --version

Hi. I think I am having the same problem:

I don't have any other versions of gpg installed, or sops for that matter. I've tried encrypting and decrypting directly with gpg, and that works fine. This is also with a brand new key.

The comment referenced, didn't help me all that much. Is this a bug, or is something wrong with my setup? Any help would be greatly appreciated.

Best regards,
Alf Kristian

This is probably something wrong with your setup. SOPS calls the gpg binary, and it's returning exit status 2, which is of course unsuccessful. Some things you could try:

Modify the code and print stdout and stderr here https://github.com/mozilla/sops/blob/master/pgp/keysource.go#L180-L195 so you can see why the GPG binary is exiting with status code 2.
Use strace to see what GPG command is actually getting called
Ensure when you encrypt and decrypt directly with GPG, you're using the exact same environment, keys, and arguments as SOPS uses.

Suddenly it started working. And I actually have no idea why. Also been trying to reproduce my error above, but cannot. At sometime I did a brew cleanup, which did remove old versions of gpg. I may have opened a new terminal after that...

Anyways, I certainly don't need any help to fix this any more :)

Best regards,
Alf Kristian

The problem suddenly re-occured... I think it has to do with the gpg-agent. For the moment, this solved it for me, adding to .bashrc or similiar (I hava a .zshrc), as described in https://www.gnupg.org/documentation/manuals/gnupg/Invoking-GPG_002dAGENT.html:

GPG_TTY=$(tty)
export GPG_TTY

I restarted the shell, and on first decrypt command I was asked for my passprase to my keys. After that all the shells seems to be able to decrypt again.

If this is the case, I would say the error message probably could hint at this solution.

Cheers,
Alf

I'm not sure the error message should hint at this, as it's only one of the many possible reasons for which calling gpg could fail. Does the stderr of calling gpg show an useful message when GPG_TTY is not set?

No, unfortunately I've seen nothing else than posted here. However, I found this issue with a google search fairly quickly, so maybe it may help others.

We may be rolling this out to the entire org, so I am sure I will see lots of variants of this. Will update the issue if I find anything else.

Did this on my colleagues Mac, and he got the same error. Adding the tty settings into his .zshrc also fixed it for him.

Confirmed gpg-agent needs to be unlocked with the private key password before sops -d will do anything useful. This happens automatically when GPG_TTY is set. To test, start clean with gpgconf --reload gpg-agent then set GPG_TTY then decrypt with sops.

Closing this issue.

@stoyle

Did this on my colleagues Mac, and he got the same error. Adding the tty settings into his .zshrc also fixed it for him.

@stoyle I tried with this resolution and appended the below 2 lines in ".bash_profile".

GPG_TTY=$(tty)
export GPG_TTY

I still have the same issue.

Could it be an issue with the sops version ?

Any info

I'd the same issue, and this page was super useful. Thanks

I don't find it user-friendly to have to set up GPG_TTY in order to decrypt a file. Couldn't sops figure this out by itself?

I had the same issue (".gnupg/secring.gpg: no such file") but my problem was that I was trying to decrypt an encrypted file that didn't have my key setup. The error message was misleading the troubleshooting - I was trying to generate somehow secring.gpg with gpg2 and in the end it was just the missing setup in the file.
