[Bug 1209146] Re: anacron jobs run with wrong environment variables

[Josep Pujadas-Jubany]

/usr/lib/update-notifier/package-data-downloader from update-notifier
uses python urllib

It seems to be problems when using proxies. In addition, urllib doesn't
supports https protocol.

https://docs.python.org/2/library/urllib.html#urllib-restrictions

Using a http proxy, adobe-flashplugin updates will work but not allways:

urllib.urlretrieve("http://archive.canonical.com/pool/partner/a/adobe-
flashplugin/adobe-flashplugin_11.2.202.425.orig.tar.gz", "adobe-
flashplugin.tar.gz")

Using a https proxy, pepflashpluguin updates will never work:

urllib.urlretrieve("https://dl-
ssl.google.com/linux/chrome/deb/pool/main/g/google-chrome-stable/google-
chrome-stable_39.0.2171.95-1_i386.deb", "google-chrome.deb")

So, scripts must be something like:

export http_proxy=http://192.168.0.1:3128
export https_proxy=https://192.168.0.1:3128
apt-get install -y flashplugin-installer
apt-get install -y pepflashplugin-installer
echo "" >> /etc/chromium-browser/default
echo ". /usr/lib/pepflashplugin-installer/pepflashplayer.sh" >> /etc/chromium-browser/default
echo "" >> /etc/chromium-browser/default
unset http_proxy
unset https_proxy
apt-get --reinstall install -y flashplugin-installer
apt-get --reinstall install -y pepflashplugin-installer

Of course, if yo do this, your corporative firewall/proxy must allow
direct connections to archive.canonical.com (http) and dl-ssl.google.com
(https).

In my opinion, update-notifier (and other applications using urllib)
should avoid python urllib

There are many bugs related (in fact, they are duplicated):

Title:
  anacron jobs run with wrong environment variables

Status in anacron package in Ubuntu:
  Confirmed

Bug description:
  In Ubuntu 13.04 (anacron-2.3-19ubuntu2) is started from
  /etc/cron.d/anacron like this

  start -q anacron

  This means anacron itself and its child processes would inherit
  environment from init/upstart not from crond. As result all
  environment variables defined in /etc/environment won't be set
  (upstart does not use pam_env.so). In my case, this leads to debtags
  job failed with network unreachable error, because my host is behind a
  proxy and http_proxy variable is defined in /etc/environment.

  The bug does not affect Debian with Init System V, because invoke-rc.d
  would start rc script directly.

  I suppose anacron should be either started directly from
  /etc/cron.d/anacron or modified so it use pam to properly initialize
  session for a job.
