Thank you for taking the time to report this bug and helping to make Ubuntu better. The error message indicates that OpenJDK 8 has not been successfully installed on a previous attempt and remains 'half- installed'. Unfortunately the logs don't indicate why that happened.
You should try to reinstall OpenJDK 8. Either use your preferred software/package manager or open a terminal and run: $ sudo apt-get install --reinstall openjdk-8-jre-headless ** Changed in: openjdk-8 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-8 in Ubuntu. https://bugs.launchpad.net/bugs/1586785 Title: package openjdk-8-jre-headless:armhf 8u77-b03-3ubuntu3 failed to install/upgrade: package openjdk-8-jre-headless:armhf is not ready for configuration cannot configure (current status 'half-installed') Status in openjdk-8 package in Ubuntu: Incomplete Bug description: i dont know ProblemType: Package DistroRelease: Ubuntu 16.04 Package: openjdk-8-jre-headless:armhf 8u77-b03-3ubuntu3 Uname: Linux 4.1.19-v7+ armv7l ApportVersion: 2.20.1-0ubuntu2 Architecture: armhf Date: Sun May 29 19:30:32 2016 DpkgHistoryLog: Start-Date: 2016-05-29 19:30:00 Commandline: apt-get install transmission-daemon transmission-cli -y Requested-By: ramesh (1000) Install: transmission-daemon:armhf (2.84-3ubuntu3), transmission-cli:armhf (2.84-3ubuntu3) DuplicateSignature: Processing triggers for systemd (229-4ubuntu4) ... dpkg: error processing package openjdk-8-jre-headless:armhf (--configure): package openjdk-8-jre-headless:armhf is not ready for configuration ErrorMessage: package openjdk-8-jre-headless:armhf is not ready for configuration cannot configure (current status 'half-installed') RelatedPackageVersions: dpkg 1.18.4ubuntu1 apt 1.2.10ubuntu1 SourcePackage: openjdk-8 Title: package openjdk-8-jre-headless:armhf 8u77-b03-3ubuntu3 failed to install/upgrade: package openjdk-8-jre-headless:armhf is not ready for configuration cannot configure (current status 'half-installed') UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-8/+bug/1586785/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~openjdk Post to : openjdk@lists.launchpad.net Unsubscribe : https://launchpad.net/~openjdk More help : https://help.launchpad.net/ListHelp
