Thanks Rob, that's interesting that you suggest the Lubuntu Software Center instead of the Ubuntu S. Ctre. I can guess why you thought of that, seeing how WattOs uses the LXDE desktop environment by default, just like Lubuntu. Anyway, I had already tried reinstalling the Ubuntu Software Centre and, as I said, it wasn't working when I reported this problem, but somehow, several days later, the Ubuntu Software Centre has been launching ok, and I don't know why it has been running ok now. I just installed a web browser ok with it a moment ago. Thanks for your thought at any rate - it is appreciated!

Dear Linux lovers,   Thanks for a great distro, fast and slim, using LXDE.  I wanted to install the Ubuntu Software Center, and I can't remember if I got it to open or to work some days ago, but have tried to relaunch it yesterday and it crashed: I got an error message such as "update apt xapian index crashed with attribute error ... in get distro".  A detail of the error message mentioned:  "root:DebFileApplication import".   I found a website that addressed that type of error albeit in a different context (their Ubuntu Software Center crashed after installing Ice software):   http://askubuntu.com/questions/147279/software-center-not-opening-after-installing-ice-from-peppermint .  I tried the steps similar to those suggested there:   1st step:gksu leafpad /etc/*releaseChanging (I think the original said something like):DISTRIB_ID=UbuntuDISTRIB_RELEASE=11.10DISTRIB_CODENAME=preciseDISTRIB_DESCRIPTION="wattOS R6"to say:DISTRIB_ID=UbuntuDISTRIB_RELEASE=12.04.01DISTRIB_CODENAME=preciseDISTRIB_DESCRIPTION="wattOS R6"and saved the file   2nd Step:gksu leafpad /etc/*issueand changed to:Ubuntu 12.04.01 LTS \n \lthen saved.This managed to get Ubuntu Software Center started at least, but it then crashed without any error message after the circling flash-like 'hourglass' symbol twirled for a few seconds.  Please could you advise me how to fix this?  I had earlier tried reinstalling the Software Center and fixing the broken packages on Synaptic Package Manager.Thanks a lot!Jose This post was edited by Jose Jurado Aranda at October 4, 2012 10:41:33 AM PDT
