Thanks for your report. From this line of the Bug Description: DistroRelease: elementary 0.4.1
it seems that you are not experiencing this issue with Ubuntu, but with elementary OS. We are not able to investigate problems or provide support for operating systems different from Ubuntu, even if they derive from Ubuntu, like in this case. Since we use this bug tracker to track bugs in Ubuntu, I'm marking this bug as Invalid. If you believe this is actually a bug in Ubuntu and that elementary OS is inheriting it, please file a new bug report with all the logs generated and captured on an Ubuntu system. Thanks! ** Changed in: nss (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1842255 Title: package libnss3:amd64 2:3.28.4-0ubuntu0.16.04.6 [origin: Ubuntu] failed to install/upgrade: package libnss3:amd64 is already installed and configured To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nss/+bug/1842255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
