linaro-image-tools & proxy problem

[fgu]

This problem is somehow also related to the bug #670711 (linaro-media-create for headless + hwpack installs packages from net).

When using the linaro-media-create script for ux500 platform, there is some apt-get commands that can't be fullfilled due to the missing http_proxy env variable.
A possible solution proposed by asac was to use a new SUDO="sudo -E" and ${SUDO} variable in the linaro-media-create script + copying the needed apt.conf file and apt.conf.d directory to the chroot environnment.

Example of l-m-c output for ux500 used behind a proxy:

I don't see why apt.conf file and apt.conf.d need to be copied to the chroot -- shouldn't it be enough to just use 'sudo -E'?

[Martin Ohlsson (martin-ohlson)]

It might be that apt.conf and apt.conf.d/ contains configuration for the proxy.

[Guilherme Salgado (salgado)]

But apt-get should use the proxy specified in the http_proxy environment
variable, so there's no need to use an apt-specific config for that.

[Spring Zhang (qzhang)]

Seems apt-get will ignore http_proxy setting and using apt.conf directly, at least on my Ubuntu Lucid 10.04.

If anybody is willing to test a patch please ping me on IRC; I'd like to make sure it works for you guys before committing to trunk.

[Loïc Minier (lool)]

it just popped back to my mind that this only allows creation of an image in a proxy-ed environment, but the installed system will lack proxy configuration entirely!

I'm reopening this for discussion; do we want to:
a) do just enough to use the proxy during image creation
b) setup the proxy in the target system
c) add a flag to select between behavior a) and b)

Currently we did a)

[Loïc Minier (lool)]

(We can just close the bug if we decide we want a) alone)

[Guilherme Salgado (salgado)]

I think it'd be nice to have a way to configure a proxy on the generated
image, but I think it should be something that the user specifies
explicitly (e.g. an extra arg to l-m-c) rather than us automatically
using the proxy that was used in the host system.

[Loïc Minier (lool)]

Fair enough
