[Bug 1236233] Re: BIOS that SMIBIOS is not fuly supported by dmidecode causes image autmatic installation fail


It turns out that dmidecode has had its boundary moved up 2.8 for saucy.
This does not fix the issue but makes it much much less likely to be hit
in saucy release images at least.

  BIOS that SMIBIOS is not fuly supported by dmidecode causes image

Bug description:
  Image: Ubuntu 12.04 LTS

  The suffix of hostname is too long and makes ubiqutiy automatic installation failed
  because suffix contains the warring message of dmidecode.

  Here is the error message in /var/log/installer/debug when installtion
  is failed.

  Traceback (most recent call last):
    File "/usr/lib/ubiquity/plugins/ubi-usersetup.py", line 394, in info_loop
      self.hostname_error(make_error_string(self.controller, errors))
    File "/usr/lib/ubiquity/plugins/ubi-usersetup.py", line 69, in make_error_string
      return "\n".join([controller.get_string(error) for error in errors])
  TypeError: sequence item 0: expected string, NoneType found

  In automation installtion, ubiquity uses product name from BIOS as hostname suffix by 
  parsing dmidecode output, but if a SMBIOS version is large thatn the version dmidecode supported,
  the output of `dmidecode -s system-product-name` or `dmidecode -s system-version` 
  contains the following warring message, so that hostname suffix is invalid.

  The warring message is

  # SMBIOS implementations newer than version 2.7 are not
  # fully supported by this version of dmidecode.
