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:
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.
Do you want to continue? [Y/n] y

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.

    Also had this problem going from 16.04 to 18.04. Your solution works there too.

  • faced this problem when upgrading my server from 16.04 to 18.04. This rename trick worked fine, and the server was able to install all upgrades. Commented Jun 18, 2020 at 15:50
