Public bug reported:
Since migration from gnupg 1.x to 2.1.15, gpg cannot decrypt my files
anymore:
$ gpg -d < foo.gpg
gpg: encrypted with 4096-bit ELG key, ID XXXXXXXXX, created XXXX-XX-XX
"XXX <xxx>"
gpg: public key decryption failed: Operation cancelled
gpg: decryption failed: No secret key
Increasing the gpg-agent loglevel reveals the following (note that in
the whole process I was never prompted for my passphrase):
gpg-agent[11397] DBG: chan_5 -> INQUIRE PINENTRY_LAUNCHED 11477
gpg-agent[11397] DBG: chan_5 <- END
gpg-agent[11397] DBG: chan_6 -> SETKEYINFO n/XXXXXXXXXXXXXXXXX
gpg-agent[11397] DBG: chan_6 <- OK
gpg-agent[11397] DBG: chan_6 -> SETDESC Please enter the passphrase to unlock
the OpenPGP secret key: ......

This looks a lot like https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=839547 -- which has a fix in pinentry/0.9.7-6 but
hasn't made it to Ubuntu 16.10 yet.
