16.04 regression bug lshw -C memory does not display module info

[Damiön la Bagh]

Summary:
There is yet another regression bug in 16.04. This time in the packaging of lshw. If you build lshw from source on 16.04LTS using apt-get source lshw the functionality is restored.

Problem:

In 14.04LTS sudo lshw -C memory shows the information necessary to view your memory modules without having to open the computer case.

product: KHX2666C15D4/8G
          vendor: Undefined
          physical id: 0
          serial: XXXXXXX
          slot: DIMM_A1
          size: 8GiB
          width: 64 bits
          clock: 2666MHz (0.4ns)

In 16.04LTS sudo lshw -C memory shows ano nothing more about the installed memory.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm experiencing the same issue but it seems to be a general issue with all classes in lshw.

I have two identical systems with the same hardware and on my 14.04 server I can run

# lshw -C system
host01
    description: Rack Mount Chassis
    product: PowerEdge 1950 ()
    vendor: Dell Inc.
    serial: XXXXXXX
    width: 64 bits
    capabilities: smbios-2.5 dmi-2.5 vsyscall32
    configuration: boot=normal chassis=rackmount uuid=23454B4D-4800-1200-2323-C8A04E4C4832

and on the 16.04 server it only returns

# lshw -C system
host02

I just noticed a new version of lshw ( 02.17-1.1ubuntu3.1 ) seems to have fixed this issue.

Can confirm this bug has been fixed in the latest update of 16.04LTS

Big thank you to the team that fixed this!

This also (still) happens on 15.10 with lshw B.02.17 (02.17-1.1ubuntu3.1)
