I got a strange error after upgrading Ubuntu 16.04 to 16.10.

The Software Updater suggests a partial update:

Could not install 'systemd-shim'

The upgrade will continue but the 'systemd-shim' package may not be in a working state. Please consider submitting a bug report about it.

subprocess installed post-removal script returned error exit status 2

sudo apt-get update finishes without any error.

sudo apt-get remove outputs this

The following packages will be REMOVED:
  systemd-shim
0 to upgrade, 0 to newly install, 1 to remove and 0 not to upgrade.
1 not fully installed or removed.
After this operation, 71.7 kB disk space will be freed.

Please help me to fix this error. Thank you.

  1. Using the terminal, rename /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service to /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.bak:

    sudo mv /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.bak
    
  2. Proceed to run sudo apt upgrade again.

Hopefully no more systemd-shim errors should appear.

Rename the file back to what it was if you have any issues.
