Title:
Lubuntu 14.04 HWE update problem: libgbm1-lts-xenial does not provide
libgbm1
Status in mesa-lts-xenial package in Ubuntu:
Incomplete
Bug description:
Installed Lubuntu 14.04 i386.
I used the apt line for all HWE updates from the ubuntu wiki, to update each
stack manually. E.g., for xenial:
sudo apt-get install --install-recommends linux-generic-lts-xenial
xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial
xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial
libwayland-egl1-mesa-lts-xenial
( https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Desktop )
* The kernel stacks updated with no problem.
* When I try to update the graphics HWE stack from *-vivid to *-willy or
*-xenial, apt wants to uninstall a lot of stuff, among them:
abiword libabiword-3.0 audacious audacious-plugins lubuntu-desktop
I did the update with the Xenial stack anyway, and tried to find the
problem while installing uninstalled (non-lib) stuff back.
Worked my way to libgbm1 through "X depends on Y, but it is not going
to be installed" errors.
libgbm1 has libgbm1-lts-* versions, and libgbm1-lts-xenial
(11.2.0-1ubuntu2~trusty1) got installed with the xenial HWE stack.
I noticed that some packages, e.g. libgbm1 and mesa-vdpau-drivers
stayed installed although they both have -lts-* versions.
1) Shouldn't the libgbm1-lts-* packages (that do not depend on libgbm1)
provide libgbm1?
Or did the API change?
http://answers.ros.org/question/203610/ubuntu-14042-unmet-dependencies-similar-for-14043/
looks connected, but their solution -- to also install some -dev-lts-* pkgs
-- seems like more of a workaround if they rebuilt the pkg, and I don't think
it will help a more complex dependency problem.
2) Did I update the stack incorrectly? Is there a
better/automated/reliable method?
Aside from libgbm1, the base mesa-vdpau-drivers stayed installed even
though I upgraded up to the vivid graphics stack---probably mesa-
vdpau-drivers-lts-* was missing from the apt line because it is not
necessary to have installed (not all systems can or want to do vdpau
accel)?
