@roky core has the repos set to stable, the lxappearance from testing and sid is broken. if it works for you, i think you have sergio's version of it.
@alfred_e_newman enable the stable repos in /etc/apt/sources.list and as root in a terminal use
apt-get install lxappearance/stable
or download the package from here http://packages.debian.org/squeeze/i386 ... e/download
, open a terminal as root in the download directory and run
dpkg -i lxappearance_0.4.0-1_i386.deb
either way is fine.
to hold on the package from updating use
echo lxappearance hold|dpkg --set-selections
once a new version of lxappearance hits testing you take it off hold with
echo lxappearance install|dpkg --set-selections
once you are done you can disable the stable repos, i have a feeling that they are all ready enabled by anti.
some reading on the commands i used http://manual.aptosid.com/en/sys-admin-apt-en.htm
