Dear Maintainer,
The powerbtn-acpi-support.sh script in the acpi-support-base package
will look for previous configuration scripts. Namely, it looks for
powerbtn.sh and powerbtn.sh.dpkg-back. However, it does not check for
power.sh. As I understand it, this script has not been used in a long
time, but it is still present on some systems, while powerbtn.sh is not.
Normally this is not an issue, but it does sometimes cause problems such
as bug #694775. While power.sh calls CheckUPowerPolicy,
powerbtn-acpi-support.sh does not. As a result, upowerd may be running,
and certain desktop environments (such as MATE), may be expecting to
receive power events, but they will get them too late. By the time
upowerd sends the event, acpid will already be shutting the system down.
I am attaching a proposed patch. It adds CheckUPowerPolicy to
powerbtn-acpi-support.sh and also checks for the existence of power.sh.
