Comment 11 for bug 1500768

So you leave all users of the trusty-updates with packages installed that are newer than what is available in the archives and hence take the chance to get proper security updates in the future?

# apt-cache policy python3.4
python3.4:
  Installed: 3.4.3-1ubuntu1~14.04.1
  Candidate: 3.4.3-1ubuntu1~14.04.1
  Version table:
 *** 3.4.3-1ubuntu1~14.04.1 0
        100 /var/lib/dpkg/status
     3.4.0-2ubuntu1.1 0
        500 http://ubuntu.ethz.ch/ubuntu/ trusty-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 Packages
     3.4.0-2ubuntu1 0
        500 http://ubuntu.ethz.ch/ubuntu/ trusty/main amd64 Packages

Please do reverting in the future _only_ by uploading a package with properly increased version number, e.g. 3.4.3+really3.4.0-0ubuntu1~14.04.1.
