[Bug 1536353] Re: [regression] Printer drivers install is broken as lsb package is not available anymore

[Till Kamppeter]

Attached is a debdiff to re-introduce the LSB compatibility binary
packages to the lsb source package of Ubuntu. I have tested an Epson
driver package with these packages installed and I can install the
package, get clean ldd output on all its executables and libraries and I
can run its executables.

** Changed in: cups-filters (Ubuntu)
       Status: Confirmed => Fix Released

** Changed in: lsb (Ubuntu)
       Status: Confirmed => Fix Committed

** Patch added: "lsb_9.20160110_9.20160110ubuntu1.debdiff"

Title:
  [regression] Printer drivers install is broken as lsb package is not
  available anymore

Status in cups-filters package in Ubuntu:
  Fix Released
Status in epson-inkjet-printer-escpr package in Ubuntu:
  Fix Released
Status in lsb package in Ubuntu:
  Fix Committed
Status in system-config-printer package in Ubuntu:
  Invalid

Bug description:
  Starting with Xenial, lsb compatibility packages were dropped (besides
  lsb-release and lsb-base):

  lsb (9.20150826) unstable; urgency=low

    * Drop all the LSB compatibility packages besides lsb-release and lsb-base
      - Drop packages-availability checking in lsb-release
      - Truncate README.Debian to a minimum
      - Document this in lsb-base.NEWS.Debian
    * Change the versioning number to avoid any ambiguity; use joeyh's
      version.date, with version being Debian next stable's

  The problem is that downloadable printer drivers (like the ones from
  Openprinting, but also from other available providers) that are
  suggested when installing a printer on Ubuntu depends on lsb, which is
  not available anymore:

  epson-inkjet-printer-201106w:
   Dépend: lsb (>=3.2) but it is not installable

  This triggers a regression where it is not possible to setup a printer
  this way (downloading a driver where no local driver is available)
  anymore.

  I see two possible solutions:

  - Add a proper replaces field to one of the remaining lsb-* packages,
  to hopefully fix missing lsb package (maybe it would be useful to also
  replace other compability packages that are not built anymore).

  - Re-introduce LSB compatibility packages, but that might be an
  overkill.
