As of 16.04, because the LSB specifies ABIs for various libraries that are no longer supported in Ubuntu as obsolete, the packages for the lsb modules have been dropped in both Debian and Ubuntu. This includes dropping of lsb-core, which is the component which provides the LSB-mandated ELF loader path - without which no lsb executable will work. This SRU will restore the bare minimum of LSB compatibility necessary to support known third-party LSB printer driver packages on Ubuntu 16.04. [Regression potential] The reintroduced 'lsb' binary package is known to not fully satisfy the requirements for a complete LSB-compliant system. This is a regression vs. Ubuntu 14.04; so anyone using LSB packages on Ubuntu 14.04 who upgrades to Ubuntu 16.04 may have the upgrade succeed without any warning from the package manager. As there are very few lsb packages in use in the wild, this is considered an acceptable regression, especially as this will land before the first 16.04 point release. [Test case] 1. Download the epsion 201106w printer driver package from http://download.ebz.epson.net/dsc/op/stable/debian/dists/lsb3.2/main/binary-amd64/epson-inkjet-printer-201106w_1.0.1-1lsb3.2_amd64.deb 2. Install the package and confirm that its dependencies are not satisfiable. 3. Enable xenial-proposed. 4. Install the package again and confirm that the dependencies are satisfied. 5. Verify that /opt/epson-inkjet-printer-201106w/cups/lib/filter/epson_inkjet_printer_filter can be run without errors about missing lsb ld.so or missing libraries. 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 -- Didier Raboud <o...@debian.org> Wed, 26 Aug 2015 12:00:00 +0200 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.
