Title:
  software-center dependency on lzma is suboptimal

Status in “apt” package in Ubuntu:
  Confirmed
Status in “software-center” package in Ubuntu:
  Confirmed
Status in “apt” source package in Precise:

Status in “software-center” source package in Precise:

Bug description:
  Third-party .deb packages -- such as Opera and Chrome -- sometimes
  have their data.tar portion compressed using LZMA.

  Until Ubuntu 11.10 this wasn't a problem, because the lzma package was installed by default. In 11.10, however, it was not (bug 868188).

  To work around this problem, software-center 5.0.2 Recommends lzma.

  However, as described by ruario in that bug report, "the lzma package
  installs the older lzma utils, which are no longer actively
  maintained[. T]he upstream maintainer of lzma utils is the same as xz
  utils. He considers xz to be the replacement for lzma, which is why it
  is backwards compatible".

  While the xz-utils source package has been in Main at least since
  Lucid, the xz-lzma binary package inside it is in Universe.

  So, xz-lzma should be promoted to Main, apt should use xz-lzma, and
  software-center should no longer Recommend lzma.
