Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error on your system when trying to install a particular package. Please execute the following command, as it will clear your package cache, in a terminal:
sudo apt-get clean Then try performing the update again. This will likely resolve your issue, but the failure could be caused by filesystem or memory corruption. So please also run a fsck on your filesystem(s) and a memory test. Thanks in advance! ** Changed in: libxdmcp (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libxdmcp in Ubuntu. https://bugs.launchpad.net/bugs/1791520 Title: package libxdmcp6 1:1.1.2-1.1 failed to install/upgrade: dpkg-deb --control subprocess returned error exit status 2 Status in libxdmcp package in Ubuntu: Invalid Bug description: NA ProblemType: Package DistroRelease: Ubuntu 18.04 Package: libxdmcp6 1:1.1.2-1.1 ProcVersionSignature: Ubuntu 4.15.0-33.36-generic 4.15.18 Uname: Linux 4.15.0-33-generic x86_64 NonfreeKernelModules: wl .tmp.unity_support_test.0: ApportVersion: 2.20.9-0ubuntu7.3 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None Date: Sun Sep 9 17:42:59 2018 Dependencies: gcc-8-base 8-20180414-1ubuntu2 libc6 2.27-3ubuntu1 libgcc1 1:8-20180414-1ubuntu2 DistUpgraded: 2018-09-09 19:28:03,076 ERROR got error from PostInstallScript ./xorg_fix_proprietary.py (g-exec-error-quark: Failed to execute child process "./xorg_fix_proprietary.py" (No such file or directory) (8)) DistroCodename: bionic DistroVariant: ubuntu DkmsStatus: bcmwl, 6.30.223.271+bdcom, 4.15.0-30-generic, x86_64: installed bcmwl, 6.30.223.271+bdcom, 4.15.0-33-generic, x86_64: installed ErrorMessage: dpkg-deb --control subprocess returned error exit status 2 GraphicsCard: Intel Corporation HD Graphics 5500 [8086:1616] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo HD Graphics 5500 [17aa:390c] InstallationDate: Installed on 2017-12-13 (270 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) MachineType: LENOVO 80E5 ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-33-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=1 Python3Details: /usr/bin/python3.6, Python 3.6.5, python3-minimal, 3.6.5-3ubuntu1 PythonDetails: /usr/bin/python2.7, Python 2.7.15rc1, python-minimal, 2.7.15~rc1-1 RelatedPackageVersions: dpkg 1.19.0.5ubuntu2 apt 1.6.3ubuntu0.1 SourcePackage: libxdmcp Title: package libxdmcp6 1:1.1.2-1.1 failed to install/upgrade: dpkg-deb --control subprocess returned error exit status 2 UpgradeStatus: Upgraded to bionic on 2018-09-09 (0 days ago) dmi.bios.date: 06/20/2014 dmi.bios.vendor: LENOVO dmi.bios.version: B0CN40WW dmi.board.asset.tag: NO Asset Tag dmi.board.name: Lenovo G50-80 dmi.board.vendor: LENOVO dmi.board.version: 31900059WIN dmi.chassis.asset.tag: NO Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo G50-80 dmi.modalias: dmi:bvnLENOVO:bvrB0CN40WW:bd06/20/2014:svnLENOVO:pn80E5:pvrLenovoG50-80:rvnLENOVO:rnLenovoG50-80:rvr31900059WIN:cvnLENOVO:ct10:cvrLenovoG50-80: dmi.product.family: IDEAPAD dmi.product.name: 80E5 dmi.product.version: Lenovo G50-80 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.13.1+18.04.20180302-0ubuntu1 version.libdrm2: libdrm2 2.4.91-2 version.libgl1-mesa-dri: libgl1-mesa-dri 18.0.5-0ubuntu0~18.04.1 version.libgl1-mesa-glx: libgl1-mesa-glx 18.0.5-0ubuntu0~18.04.1 version.xserver-xorg-core: xserver-xorg-core 2:1.19.6-1ubuntu4 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.5-1ubuntu1 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:18.0.1-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20171229-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.15-2 xserver.bootTime: Sun Sep 9 20:23:28 2018 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.19.6-1ubuntu4 xserver.video_driver: modeset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxdmcp/+bug/1791520/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
