Yeah, but packagekit doesn't download stuff, it talks with DBus. And
apt-listbugs doesn't use curl.

But thanks for that idea. /etc/apt/apt.conf.d/20packagekit calls
/usr/bin/gdbus to talk with the DBus daemon. The file itself doesn't
have that string, but one of the libraries it loads:

# ldd /usr/bin/gdbus
[…]
        libgio-2.0.so.0 => /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0 (0x00007fe7817e8000)
[…]
# strings /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0 | fgrep 'Timeout was reached'
Timeout was reached
# 

Debian Code Search underlines that finding:

http://codesearch.debian.net/search?q=%22Timeout+was+reached%22 

Source package glib2.0, file gdbusconnection.c. (The curl occurrence
is found, too.)

Ok, thanks for that detail.

Nope. Thanks for that hint. So I quite sure the issue is really caused
by to packagekit's APT hook. Which also means that apt is affected,
too. Ubuntu's bug reports actually support that assumption:
https://bugs.launchpad.net/ubuntu/+source/packagekit/+bug/1001376

Please try the above gdbus call as soon as the issue pops up again.

In the meanwhile I'm reassigning this and the mentioned bug report on
Launchpad to packagekit and marking #729527 as "affects apt and
aptitude". I'm also subscribing to these two bug reports so I'll stay
informed in case my reasoning was wrong.
