/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): https://bugs.launchpad.net/ubuntu/+source/anacron/+bug/1209146 https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/1098233 https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/1037662 https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1005837 https://bugs.launchpad.net/zc.buildout/+bug/484735 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to flashplugin-nonfree in Ubuntu. https://bugs.launchpad.net/bugs/1037662 Title: flashplugin-installer does not honor proxy settings Status in flashplugin-nonfree package in Ubuntu: Triaged Bug description: Description: Ubuntu quantal (development branch) Release: 12.10 flashplugin-installer: Installato: 11.2.202.238ubuntu1 Candidato: 11.2.202.238ubuntu1 Tabella versione: *** 11.2.202.238ubuntu1 0 500 http://archive.ubuntu.com/ubuntu/ quantal/multiverse i386 Packages 100 /var/lib/dpkg/status i'm behind a corporate proxy i can download with wget, curl and other stuffs but the plugin flashplugin-nonfree do not traverse my proxy... gui install mode and also this using terminal commands: sudo apt-get install flashplugin-nonfree nor with sudo -E apt-get install flashplugin-nonfree my env: "env | grep -i proxy" http_proxy=http://192.168.100.59:3128/ ftp_proxy=ftp://192.168.100.59:3128/ socks_proxy=socks://192.168.100.59:3128/ UBUNTU_MENUPROXY= https_proxy=https://192.168.100.59:3128/ Also i have the proxy values correctly set into /etc/apt/apt.conf to traverse the proxy for the debs... also set into /etc/sudoers Defaults env_reset Defaults env_keep="http_proxy https_proxy" Available workaround: https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/1098233 Thanks.
