Subject: qemu build fails with proxy_cmd: parameter not set

Date: Fri, 26 Oct 2018 13:46:47 -0400

[Message part 1 (text/plain, inline)]

Package: autopkgtest
Version: 5.6
Severity: important
File: /usr/bin/autopkgtest-build-qemu
Tags: patch

There seems to be some sort of interoperability issue between
autopkgtest and recent versions of APT which leads the build to
completely fail:

$ sudo autopkgtest-build-qemu stretch autopkgtest-stretch.qcow
/usr/bin/autopkgtest-build-qemu: 61: /usr/bin/autopkgtest-build-qemu: proxy_cmd: parameter not set

This is on a recent buster system. The offending code is:

        RES=`apt-config shell proxy_cmd Acquire::http::Proxy-Auto-Detect`
        eval $RES
        if [ -n "$proxy_cmd" ]; then

... and probably fails because of `set -eu` in the script. I can
confirm the RES variable is empty and therefore proxy_cmd never gets
initialized.

The attached patch fixes the issue, but it might be a little naive and
should be reviewed correctly to see why this failure occurs now. It
might be the variable changed on APT's side or something similarly
fishy.

I don't have a proxy setup here, so the patch fixes my own itch.

------------------------------------------------------------------------
autopkgtest-build-qemu: Fix uninitialized proxy_cmd variable

Apparently in some cases `apt-config shell` does not set the variable at
all. Let's be robust for that and avoid an error due to an unset
variable.

Thanks to Antoine Beaupre for debugging this!

Closes: #911963
