I achieved to poweroff my computer after the following attempts to
install my wifi proprietary driver.
However, with a previous attempt to install this driver, I'm not sure that this
package fixed the issue : I previously installed by using synaptic :

As a complement, I remember that the graphical tool for managing the
proprietary driver first displayed 3 devices which had a proprietary

then I didn't saw the 2 other devices into the list proposed by the
graphical tool.
The bug occurs each time I want to poweroff whatever the method is.

For what it's worth, some bugs can be easier to reproduce on machines
