Hi, I just encountered this bug on a mini computer board (Intel Celeron J1900 x4, 2GHz with 4096 MB of RAM). Ubuntu 15.04 Server for AMD64
I can give you every details for having this reproduced With a minimalist installation as I always do with Debian (approximately nothing is installed but Linux Kernel and apt-get - then I choose what I need and nothing else) For doing that : - I used "expert mode" by pressing "F6" at the boot of the installer (Legacy mode, not UEFI). - I didn't execute "Select and Install software". (because it loads and install many things I'm not going to use) I use the following sources.list : http://62.210.206.25:82/html/sources.list (extracted from a fully installed Ubuntu server 15.04 amd64) because when "Select and Install software" is not done, sources.list is keept untouched (so I replaced it manually from a live usb stick) Then I typed the following commands apt-get update apt-get upgrade apt-get install mate-desktop-environment lightdm Then it's freezing many times, whatever I try it always fails returning the same error : Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24) Failed to execute operation: Connection timed out dpkg: error processing package systemd (--unpack): subprocess installed post-installation script returned error exit status 1 Processing triggers for dbus (1.8.12-1ubuntu5) ... Errors were encountered while processing: systemd E: Sub-process /usr/bin/dpkg returned an error code (1) also : "error calling StartServiceByName for org.freedesktop.PolicyKit" or also : "cannot open /run/systemd/was-enabled no such file" But it continues after a while and then finish by Errors were encountered while processing: systemd E: Sub-process /usr/bin/dpkg returned an error code (1) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447654 Title: installing policykit-1 hangs under systemd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/1447654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
