    Removing HAL?

    What is the situation regarding removing HAL from the ubuntu family?
    I see long discussions about it, but nothing actually useful or conclusive.
    As I won't be doing any "clean installs" anytime soon, I will need to know when it is safe to remove it from the existing system. As an experiment, I did a dry run in maverick:

    Code:
    greenman@Wolfenstein:~$ apt-show-versions | grep hal
    hal/maverick uptodate 0.5.14-0ubuntu6
    hal-cups-utils/maverick uptodate 1.2.3+20100723-0ubuntu8.1
    hal-info/maverick uptodate 20091130-1
    libhal-storage1/maverick uptodate 0.5.14-0ubuntu6
    libhal1/maverick uptodate 0.5.14-0ubuntu6
    libkephal4/maverick uptodate 4:4.5.5-0ubuntu1ppa1

    pulseaudio-module-hal-dbg 1:0.9.14-0ubuntu20.2 installed: No available version in archive
    greenman@Wolfenstein:~$ sudo apt-get remove --purge hal hal-cups-utils hal-info libhal-storage1 libhal1

    Well, that's ugly.
    The xfce stuff I understand -- the newest xfce, just released today (17 Jan 2011) no longer depends on HAL, but that probably hasn't hit the repositories yet. But k3b-extracodecs? And GIMP? No can do, sorry.

    KDE and K3b no longer depend on HAL in 11.04. Kubuntu will likely be shipping without HAL by default in 11.04.

      Trying the same commands in 11.04 produced the following:

      Code:
      The following packages will be REMOVED:
       flegita-gimp gimp gimp-gap gimp-gluas gimp-gmic gimp-gutenprint gimp-plugin-registry gimp-resynthesizer
       gimp-texturize gimp-ufraw gtkam-gimp hal hwinfo libexo-0.3-0 libhal-storage1 libhal1 libhd16
       libk3b2-extracodecs libk3b3 libk3b3-extracodecs libnautilus-burn4 libthunar-vfs-1-2 mountmanager oxine
       pandora pmount pulseaudio-module-hal pulseaudio-module-hal-dbg squeeze xfburn xfmedia xprint
      So look like there is still stuff in 11.04 that depends on it.

        Those K3b packages in your new list are out of date and can be safely removed. (Old libraries with new package names in 11.04) For example the packages in 11.04 are libk3b6 and libk3b6-extracodecs.
