I was able to demonstrate that all of [apt-get, dpkg, aptitude, gdebi,
gdebi-gtk, synaptic] _do_ allow the $http_proxy environment variable to
propagate down to the package's install script, and therefore to `wget`:
cd /var/cache/apt/archives
rm -f flashplugin-installer*
apt-get install flashplugin-installer # to cache it
RMV(){ apt-get remove flashplugin-installer; }
RMV; http_proxy=fail:// apt-get install flashplugin-installer
RMV; http_proxy=fail:// dpkg -i flashplugin-installer*.deb
RMV; http_proxy=fail:// aptitude reinstall flashplugin-installer
RMV; http_proxy=fail:// gdebi flashplugin-installer*.deb
RMV; http_proxy=fail:// gdebi-gtk flashplugin-installer*.deb
RMV; http_proxy=fail:// synaptic& # then install flashplugin-installer
These of course all fail with a `wget` error message about wrong schema
for the proxy URL; clearly demonstrating that $http_proxy got to them.
Whereas this one:
RMV; http_proxy=fail:// software-center&
passes _no_ proxy setting to the install script -- which then proceeds
to try a fruitless direct connect.
So the actual current situation is that this problem is _fixed_ for the
other installers, at least the ones I tried, while software-center
recreates the problem for itself by purging $http_proxy from the
environment of its subprocess; or, in any case, failing to get it across
to `aptd`.
The same behaviors apply with respect to synaptic & software-center when
loaded from my window manager menus. $http_proxy is set by something
and propagates down as it should, except in software-center.
I did not test update-manager, not knowing how to trick it into thinking
a back-rev version of flashplugin-installer was on my system needing an
update.
(There's another whole set of bugs with this: my GUI-configured proxy
setting is supposed to be the same for all protocols, but only
$http_proxy is getting into my env, and `wget`, at least, interprets
this literally as proxying only HTTP.)
