Can not shutdown

[A_Man_Without_Clue <love.chaser@gmail.com>]

Hi all,

I just installed Debian testing, Debian Installer Buster Alpha 5 release.

I use LXDE and now I just found out that I cannot shut down from LXDE,
"Logout - Shutdown"

It gives the error saying "GDBUS Error System Error ENXIO No such drive
or address"

I tried with XFCE but still it won't shutdown, it just logs out instead.

What has gone wrong?
