git-annex gpg encryption fails here when GPG_AGENT_INFO is set, it needs to be supplied --use-agent to work.
Output from git-annex:
copy file (to origin...) (gpg) gpg: can't query passphrase in batch mode
gpg: decryption failed: secret key not available
Command gpg ["--batch","--no-tty","--quiet","--trust-model","always","--decrypt"] failed; exit code 2
git-annex: user error (Command gpg ["--batch","--no-tty","--quiet","--trust-model","always","--decrypt"] failed; exit code 2)
failed
Reproduced on command-line:
[0 zerodogg@browncoats ~]$ echo test > testfile
[0 zerodogg@browncoats ~]$ gpg -e testfile
[0 zerodogg@browncoats ~]$ gpg --batch --no-tty --quiet --trust-model always --decrypt testfile.gpg
gpg: can't query passphrase in batch mode
gpg: decryption failed: secret key not available
[2 zerodogg@browncoats ~]$ gpg --use-agent --batch --no-tty --quiet --trust-model always --decrypt testfile.gpg
test
[0 zerodogg@browncoats ~]$
