Q: After updating all the available updates using Synaptic package manager shut down no longer works?
The steps I did are following:
1. Open Synaptic Package manager
2. Press reload button
3. Mark all updates
4. Apply and install etc
5. Try to shut down or reboot using power icon in task bar.
A:
The original image of lubuntu has some issues regarding the shutdown using non-root user. The image of pcDuino fixed this issue. However, it got overwritten when you did update through synaptic package manger.
We can modify /usr/share/polkit-1/actions/org.freedesktop.consolekit.policy to address this issue.
