[FTBFS] v4l-utils: stop building biarch package

libjpeg is already multiarch-capable in Ubuntu, and the only reason v4l-utils wants ia32-libs is to build a biarch library package. The correct solution here is for v4l-utils to stop building lib32v4l-0 and lib32v4l-dev, which aren't used by anything else in the archive, and to instead migrate to multiarch itself.

Ah; correction, I see (when I run the right command) that ia32-libs, wine1.2 and wine1.3 all look for lib32v4l. Still, addressing this in ia32-libs would be a move in the wrong direction. I think this should still be fixed by dropping lib32v4l and fixing up the resulting breakage.

This bug was fixed in the package v4l-utils - 0.8.5-3ubuntu1

---------------
v4l-utils (0.8.5-3ubuntu1) oneiric; urgency=low

  * Stop building the lib32* packages on amd64. LP: #808064.
  * Package requires symbols jpeg_mem_src and jpeg_mem_dest from jpeg8.
    Build-depend on libjpeg8-dev.

So if I understand things correctly, in addition to wine we also need to drop the dep from ia32-libs too?

Roland: yes, I would think so.

Fast worker...Steve :-)

This bug also removed googleearth and skype packages, which don't have installation candidates (acroread is also missing), at least I think so.

Thanks for fixing wine and picasa (picasa needed wine)

You need to follow the instructions at
https://lists.ubuntu.com/archives/ubuntu-devel-announce/2011-August/000886.html
and install skype:i386 from the natty partner archive. The current version
of ia32-libs no longer provides the libraries needed by skype because these
are fully available by multiarch; as soon as there's a new i386-only skype
package for oneiric, ia32-libs will make this clear in its Breaks: field.

googleearth can also be built as an i386 package and installed via
multiarch, but for now installing it with ia32-libs is still ok.

I have this exact bug (below) but I am still running Natty and came across this issue after an upgrade. Skype and Wine1.3 no longer work. Is there a separate bug for Natty, or how should I fix this? I checked out the link above, but I'm unclear on what I should do to resolve the issue.

I have the same problem as Ben Collier. How can we fix it ?

Alexandre,

I fixed the problem by doing two things, I'm not sure which one of them fixed it, or if both did it.

First, I went into the source in the Ubuntu Software Center and unchecked all the ppa's and everything basically that isn't the default Ubuntu (Multiverse, Universe, etc) sources.

Then I did

sudo apt-get install -f

And it installed 200+ MB worth of software and resolved all my dependencies. Hope that is helpful. I'm not 100% sure about the above line, but it was something -f and I think that is right.
