Thank you for taking the time to report this bug and helping to make Ubuntu better.
I see in the log that: 9月 29 11:21:28 hostname systemd[1]: Failed to start HAProxy Load Balancer. 9月 29 11:21:28 hostname systemd[1]: haproxy.service: Failed with result 'exit-code' But at the same time your config is a customized one: mtime.conffile..etc.haproxy.haproxy.cfg: 2016-01-09T20:20:32.739917 In cases like this most of the times a configuration either was always broken (installied, tried, ignored) or is no more compatible with the upgraded version. I'd recommend to backup your custom configuration, and on the upgrade say "use the package maintainers version". This gets you going with the default conf. From there you can add your custom config piece by piece and find where you might need to change the way it is set up. Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete. If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New. ** Changed in: haproxy (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu High Availability Team, which is subscribed to haproxy in Ubuntu. https://bugs.launchpad.net/bugs/1628747 Title: package haproxy 1.6.3-1ubuntu0.1 failed to install/upgrade: サブプロセス インストール済みの post-installation スクリプト はエラー終了ステータス 1 を返しました Status in haproxy package in Ubuntu: Incomplete Bug description: at haproxy install $ sudo apt install haproxy ProblemType: Package DistroRelease: Ubuntu 16.04 Package: haproxy 1.6.3-1ubuntu0.1 ProcVersionSignature: Ubuntu 4.4.0-38.57-generic 4.4.19 Uname: Linux 4.4.0-38-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 AptOrdering: liblua5.3-0: Install haproxy: Install liblua5.3-0: Configure haproxy: Configure NULL: ConfigurePending Architecture: amd64 Date: Thu Sep 29 11:21:28 2016 ErrorMessage: サブプロセス インストール済みの post-installation スクリプト はエラー終了ステータス 1 を返しました InstallationDate: Installed on 2015-10-23 (341 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.12~ubuntu16.04.1 SourcePackage: haproxy Title: package haproxy 1.6.3-1ubuntu0.1 failed to install/upgrade: サブプロセス インストール済みの post-installation スクリプト はエラー終了ステータス 1 を返しました UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.haproxy.haproxy.cfg: 2016-01-09T20:20:32.739917 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/haproxy/+bug/1628747/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-ha Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-ha More help : https://help.launchpad.net/ListHelp
