The logs attached to your bug report show that: - You have an /etc/update-motd.d/10-help-text.txt file on your system which has been customized to contain Indonesian help text in a way that, if it was done by a package, would not be policy compliant - This customization generated a prompt on upgrade asking whether to keep your installed version of this conffile, or take the new version of the conffile from the package - Either from you, or from some software component, the prompt was sent an end of file (^D) instead of an answer.
Questions for you: - what tool did you use to apply software updates? - did you see this prompt about the conffile? if so, what action did you take? - do you know why /etc/update-motd.d/10-help-text.txt is modified on your system? I also see from the log that this was an error that happened when you were applying updates in June. I don't know why this apport bug report is only being submitted now. It's understandable if you don't remember what you did as part of an upgrade back in June; however, if at all possible, we would like to understand exactly what happened as part of your upgrade in order to best fix this bug. I am able to reproduce this problem just by running apt from a commandline and hitting ^D at a conffile prompt. This part is definitely a dpkg bug, as dpkg should use the default option (default=N) on EOF instead of aborting. ** Changed in: base-files (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to base-files in Ubuntu. https://bugs.launchpad.net/bugs/1637684 Title: package base-files 9.4ubuntu4.2 failed to install/upgrade: end of file on stdin at conffile prompt Status in base-files package in Ubuntu: Incomplete Bug description: I don'know ProblemType: Package DistroRelease: Ubuntu 16.04 Package: base-files 9.4ubuntu4.2 ProcVersionSignature: Ubuntu 4.4.0-36.55-generic 4.4.16 Uname: Linux 4.4.0-36-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 Date: Wed Jun 29 02:11:08 2016 Dependencies: Df: Filesystem 1K-blocks Used Available Use% Mounted on udev 8036636 0 8036636 0% /dev ErrorMessage: end of file on stdin at conffile prompt InstallationDate: Installed on 2016-10-29 (0 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.12~ubuntu16.04.1 SourcePackage: base-files Title: package base-files 9.4ubuntu4.2 failed to install/upgrade: end of file on stdin at conffile prompt UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.update-motd.d.10-help-text: 2016-09-05T02:11:11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/base-files/+bug/1637684/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
