Public bug reported: This problem started some weeks or months ago, I can never install updates running the 'Software Updater' (update-manager). The updater launches OK, it checks for updates correctly, but upon clicking the 'Install Now' button, a brief message reads "waiting for authentication" and then the window goes away, and no updates are installed.
Running the update-manager from a terminal does not produce any errors or warnings. Everything happens as explained above, and the program silently fails to install updates. However, running apt-get update + apt-get upgrade works perfectly from the terminal. The problem is similar to the one reported here, https://askubuntu.com/questions/546363/software-updater-software-updates-not-working-on-14-04-lts but the solution suggested (installing a threading.py file) does not work for me. I have already a threading.py file in my /usr/lib/python3.4 directory, but replacing it with a newer version from https://hg.python.org/cpython/file/3.4/Lib/threading.py did not fix the issue. Please help me debug further or point me to a solution. lsb_release -rd Description: Ubuntu 14.04.4 LTS Release: 14.04 apt-cache policy update-manager update-manager: Installed: 1:0.196.14 Candidate: 1:0.196.14 Version table: *** 1:0.196.14 0 500 http://archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages 100 /var/lib/dpkg/status 1:0.196.11 0 500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: update-manager 1:0.196.14 ProcVersionSignature: Ubuntu 3.13.0-83.127-generic 3.13.11-ckt35 Uname: Linux 3.13.0-83-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 CurrentDesktop: Unity Date: Thu Apr 21 09:07:37 2016 InstallationDate: Installed on 2012-10-29 (1269 days ago) InstallationMedia: Ubuntu 12.04.1 LTS "Precise Pangolin" - Release amd64 (20120823.1) PackageArchitecture: all SourcePackage: update-manager UpgradeStatus: Upgraded to trusty on 2014-11-25 (512 days ago) ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug third-party-packages trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573003 Title: Software Updater (update-manager) window goes away, updates are not installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1573003/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
