[Bug 455174] [NEW] mandos-client hangs during installation

[Lenny Foner]

Public bug reported:

Binary package hint: mandos

In Ubuntu karmic (development branch) [last ran update-manager sometime
earlier today], mandos server & client 1.0.11-1build1, in a system
originally installed from the AMD64 alternate install (Linux
2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64
GNU/Linux):

I just used Synaptic to attempt to install mandos and mandos-client, and
it hung partway through, during the installation of mandos-client.  It's
not using any runtime; it's just wedged.  The last few lines in
Synaptic's progress output were:

Setting up mandos (1.0.11-1build1) ...

.+++++++++++++++++++++++++......++++++++++..++++++++++.++++++++++..+++++.++++++++++.+++++++++++++++++++++++++..++++++++++.++++++++++.++++++++++++++++++++++++++++++>.+++++++++++++++++++++++++...................................\.............+++++

...and then nothing.  The relevant lines from ps -elf --forest:

It's now been hung for half an hour or so.

Oh wait, WTF?  At some point while I was assembling this bug report, it
printed more output:

..++++++++++...+++++++++++++++..+++++++++++++++.++++++++++.++++++++++.+++++....++++++++++.++++++++++.++++++++++.+++++++++++++++++++++++++.++++++++++..+++++++++++++++>++++++++++>+++++.......................+++++^^^^^

Processing triggers for python-support ...

...and then declared that it had finished.

So it looks like it hung for a LOOONG time between generating a pair of
keys (I'm guessing, since it printed two separate lines of plusses and
minuses).  Something that can (a) hang for 30 minutes and (b) use no CPU
time during that hang will make everything think there's a bug there,
and I'm reasonably sure there is.  Certainly it shouldn't take that long
to generate keys on a fast machine (and it wasn't using CPU), and I
believe it had actually finished generating that first line of +/- in
seconds and that it wasn't accomplishing any useful work for half an
hour until it generated the second line.  Maybe  GPG ran out of entropy
until it had time to gather more?  The machine had been up about an hour
before I tried the installation, and had one window open via its native
display (just an xterm that I did a ps on to debug it) and two ssh
sessions and one Firefox (this one); the latter two of which I started
in order to debug and which clearly weren't enough on their own to give
the machine more entropy (since they'd been up for 20-30 minutes before
the installation suddenly continued).  If it really -is- running out of
entropy, then the installer should attempt to warn the user or
something, but it's hard to believe it hasn't seen enough activity to
collect enough bits.
