** Attachment added: "term.log" https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1644541/+attachment/4795997/+files/term.log -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1644541 Title: Update stuck at “configuring unattended-upgrades” Status in unattended-upgrades package in Ubuntu: Confirmed Bug description: On basically fresh install from ubuntu-16.04.1-desktop-amd64.iso; no updates or installs had been applied since installing the OS from the media. During execution of "Software Updater", it freezes indefinitely while "Installing updates..." at the step marked "Configuring unattended- upgrades." It appears that this happens if System Settings->Software & Updates->Updates, "Automatically check for updates" has been set to "Never." If that is instead set to "Daily" and the following are then set in /etc/apt/apt.conf.d/10periodic then the update succeeds: APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "1"; APT::Periodic::AutocleanInterval "7"; APT::Periodic::Unattended-Upgrade "1"; Someone else had asked about this issue at AskUbuntu. Their question along with my answer (from Kevin) provide some further details: http://askubuntu.com/questions/851371/update-stuck-at-configuring- unattended-upgrades-software-updater-turned-black/852110#852110 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1644541/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
