I get this error because downloads need to use a HTTP proxy. The system is configured to use the proxy (i.e. http_proxy environment variable is set) but this environment setting is not used when installing packages through the update-manager.
If I manually run sudo -i /usr/lib/update-notifier/package-data-downloader after I get this error everything works fine. The main difference is the -i flag to sudo which enables the normal system environment (containing the http_proxy variable) for the package-data-downloader. http_proxy is set in /etc/environment: http_proxy="http://proxy.example.com:3128/"; In addition, I got some proxy configuration in /etc/apt/apt.conf: Acquire::http::proxy "http://proxy.example.com:3128/";; Acquire::ftp::proxy "ftp://proxy.example.com:3128/";; Acquire::https::proxy "https://proxy.example.com:3128/";; Acquire::socks::proxy "socks://proxy.example.com:3128/"; The fix was taken from https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/983559 Also https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/979477 seems to be related, however, there is a big mixup between honoring APT settings, system settings, allowing http_proxy to be passed via sudo, so I'm unsure if there is a duplicate bug situation or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1005837 Title: update-notifier-common To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1005837/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
