[Bug 1332864] [NEW] unable to encrypt or sign emails or files with gnupg2

[Nosphky]

Public bug reported:

With a new installation of UbuntuStudio 14.04 LTS, and moving my
applications over from a dual boot Windows7 to ubuntu, I wanted to
continue using Thunderbird and enigmail to encrypt and sign emails.  I
also wanted to use Kleopatra and /or GPA gui's which I was used to in
Windows.

So I installed gnupg2:   gnupg2 2.0.22-3ubuntu1

and Kleopatra : kleopatra 4:4.13.1-0ubuntu0.1

and GPA : gpa 0.9.4-1

(having checked with gnupg.org that gnupg 1 and 2 should be able to
coexist).

I expected to send a signed email.

Thunderbird would not send a signed email - giving a 'bad password'
message although it had not asked me for a password.

 Thunderbird had correctly found /usr/bin/gpg and my public and private
keyrings had been correctly imported by enigmail's key manager and they
displayed correctly in Kleopatra and in GPA.

I  tried in a terminal to sign, encrypt files.    Using gpg, the signing
and verifying worked after asking for the password but produced a
message saying :

gpg: problem with the agent - disabling agent use

Using gpg2,   signing and clearsigning failed  without asking for a
password with this error :

gpg: problem with the agent: No PINentry
gpg: no default secret key: Operation cancelled

Using gpg2, files signed earlier by gpg could be verified.

Kleopatra and GPA would not sign nor verify files.

I checked, and gpg-agent seemed to be running.  Both pinentry-gtk-2 and
pinentry-Qt4 were installed.  ' Pinentry' in the terminal produced a
response from Qt4 and getpin seemed to work ok.

I removed gnupg2 , Kleopatra and GPA from the pc and rebooted.

Thunderbird 24.6 with enigmail 1.6 worked correctly using pinentry-gtk-2
dialog to request password and then sending signed and encrypted mail
using the default installation of gnupg 1.4.16
