svn not using gpg-agent

[Michael Thayer]

(Not subscribed, please CC me on answers. Thanks!)

Hello,

I suspect this is a user problem somewhere, but since I upgraded to
Ubuntu 16.10 (Subversion 1.9.4 versus 1.9.3 in 16.04) svn has stopped
using GPG-Agent and started using GNOME Keyring to store my password.
As a test, I deleted all GNOME Keyring passwords, deleted the local
.subversion folder and recreated it with "svn --version", changed the
password-stores line to "password-stores = gpg-agent" and updated. The
password was saved to the GNOME Keyring again. For a little bit more
security I would really prefer GPG-Agent though. (For the record, the
GNOME Keyring FAQ seems to disagree with your FAQ about other
applications accessing stored passwords.<1><2> But it seems about the
best option just now. It would be great if svn could fork off a daemon
process itself which would hang around for a while and do the actual
work, but I digress.)

Any ideas welcome.

Thanks!

Michael

GPG-Agent and started using GNOME Keyring to store my password.

In Ubuntu 16.10, gnupg changed from the 1.4.x series to the 2.x series.
With that, gpg-agent now will start on-demand when needed, whereas with
the old gnupg it needed to be manually started.

Svn currently detects whether it can use gpg-agent by looking for the
UNIX socket that's used to communicate with the agent. It finds this
either through the GPG_AGENT_INFO environment variable or looking for
~/.gnupg/S.gpg-agent socket. It sounds like neither of those exist in
your setup.

$GPG_AGENT_INFO should be defined for your X session by
/etc/X11/Xsession.d/90gpg-agent, and there are also some hints in the
file about how to ensure the agent gets started.

While the above isn't a solution, hopefully it's enough information to
figure out where the disconnect is.

Cheers,

Thank you! It seems like that script isn't getting executed, possibly
due to the Wayland session. If I source it manually things work again.
