Thanks for reporting. Ubuntu is not a rolling release, so package versions are usually not updated from the one initially provided in a certain Ubuntu release. Newer versions of packages are added to newer Ubuntu releases.
There are a couple of exceptions. The first one is major bugs or security issues where the issue is fixed by applying a patch for that specific issue in the form of a Stable Release Upgrade ( https://wiki.ubuntu.com/StableReleaseUpdates#Procedure). As you can see from https://launchpad.net/ubuntu/+source/mailman, for 16.04 a couple of security issues seems to have been fixed in 1:2.1.20-1ubuntu0.3. The second case is offering a newer version of the package in the backports pocket, which makes a newer version of a package optionally available and installable on an older Ubuntu release. See https://wiki.ubuntu.com/UbuntuBackports#Requesting_a_Backport for details on how to request a backport. When reporting bugs in the future please use apport by using 'ubuntu- bug' and the name of the package affected. This will mark the correct package as affected and automatically add other relevant information such as version numbers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803838 Title: Mailman Upgrade to 2.1.29 - Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mailman/+bug/1803838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
