Original GitHub issue: https://github.com/netblue30/firejail/issues/1989

When running with the default profile I get errors about gpg-agent. For example when running less tmpfile I get:

gpg-connect-agent: no running gpg-agent - starting '/usr/bin/gpg-agent'
gpg-connect-agent: failed to create temporary file '/home/username/.gnupg/.#lk0x00000c45ee6397f0.hostname.12': Permission denied
gpg-connect-agent: can't connect to the agent: Permission denied
gpg-connect-agent: error sending standard options: No agent running

Firejail version:

firejail version 0.9.54

Compile time support:
	- AppArmor support is enabled
	- AppImage support is enabled
	- bind support is enabled
	- chroot support is enabled
	- file and directory whitelisting support is enabled
	- file transfer support is enabled
	- networking support is enabled
	- overlayfs support is enabled
	- private-home support is enabled
	- seccomp-bpf support is enabled
	- user namespace support is enabled
	- X11 sandboxing support is enabled

Running on Arch Linux with linux-hardened-apparmor kernel.

Even when running with no profile it seems like firejail is doing something with the gpg-agent. I ran firejail --noprofile /usr/bin/less tmpfile and got the output:

Parent pid 14574, child pid 14575
Child process initialized in 23.57 ms
gpg-connect-agent: no running gpg-agent - starting '/usr/bin/gpg-agent'
gpg-connect-agent: waiting for the agent to come up ... (5s)
gpg-connect-agent: connection to agent established

When the main process (less) exited, it seems the firejail invocation was still running and I had to use Ctrl-C to get the shell back.

NOTE: This doesn't happen only for less- I see it in other programs as well.

@chiraag-nataraj commented on GitHub (Jun 11, 2018):

Hmm, here's my output when I run firejail --noprofile /usr/bin/less /etc/profile (as an example):

Parent pid 12602, child pid 12603
Child process initialized in 35.74 ms
<less pops up>
Parent is shutting down, bye...

In other words, I can't reproduce this. I'm on Debian running a customized kernel, but I don't think the kernel configuration has much to do with this (unless the linux-hardened-apparmor kernel sets other things besides just the kernel?).

When the main process (less) exited, it seems the firejail invocation was still running and I had to use Ctrl-C to get the shell back.

I have seen this before (#1422 as an example). That being said, gpg-agent shouldn't be running at all for less! This is really bizarre...

Thanks for the quick response!
Yes, this is strange. BTW, this seems to happen for every firejailed program, not just less.

Right, but other programs might actually use gpg-agent. It's very curious because there's absolutely no reason less should be spawning gpg-agent

So if you spawn less tmpfile (no firejail) and look at something like htop in tree mode (so you can see parent and children processes), does less spawn anything? I wonder...

Nope, when running less without firejail gpg-agent is not spawned.

Huh, that's even more weird. Does it spawn if you just run firejail (or firejail --noprofile)?

Okay, that definitely shouldn't be happening...

Can you try /usr/bin/firejail instead of firejail?

@Vincent43 that yielded the same result

OK, I think I understand where this is coming from- I have the following line in my ~/.profile: gpg-connect-agent updatestartuptty /bye >/dev/null.
My login shell is set to zsh and I sourced ~/.profile from my ~/.zshenv, so I guess firejail spawned a new shell each time that made these calls to gpg-connect-agent.
When I commented out my ~/.zshenv the problem was resolved.

Thanks a lot for all your help!
