No public key

[SMesser]

How do I tell QtPass to use my public key?

From the command line, gpg says I have one

$ gpg --list-secret-keys --keyid-format LONG
/Users/sarah/.gnupg/pubring.kbx
-------------------------------
sec   rsa2048/DB836B258B5D7AA2 2017-04-06 [SC]
      0B83F95C40A2B5B97BA41901DB836B258B5D7AA2
uid                 [ultimate] Sarah Messer <sarah.messer@mycomputer.org>
ssb   rsa2048/270E0585963ADC94 2017-04-06 [E]

When I try to create a password in QtPass, I get
gpg: gpg-agent: skipped: No public key gpg: [stdin]: encryption failed: No public key

https://qtpass.org/docs/md__f_a_q.html asks "Is the folder initialized?" But doesn't say which folder or how to initialize it. The QtPass "Users" button shows a single user, which is checked:
Sarah Messer <sarah.messer@mycomputer.org> DB836B258B5D7AA2 created 4/6/17 2:51 PM

FWIW, I'm using Mac Sierra /OSX, with QtPass and Qt5 installed via Brew. The key pair was generated with gpg2 --full-generate-key, and installation followed the pattern at https://qtpass.org/ until qmake && make && macdeployqt QtPass.app terminated with a generic usage message for qmake, but no actual error message.

The Configuration -- Programs tab says I'm using "Native git/gpg". (I have git installed on the machine, but am confused as to why QtPass needs it, and I haven't done a git init or anything similar in ~/.gnupg/. ls -al /usr/local/bin/gpg2 and ls -al /usr/bin/git confirms I have read permissions (755) on both the "Native git/gpg" files. The "pwgen" entry is currently blank.

echo $GPGHOME returns blank.

Thanks

The quickest fix would be to edit the .gpg-id file in the .password-store

Possibly you can use the "User" management option in QtPass . .

[annejan]

On first use QtPass should ask you for users (gpg id's) when initialising the password-store . .
