I install apt in my redhat9 box, learn to use apt to upgrade gcc,gcc-c++,cpp,libsdtc++,libgcc,libsdtc++-devel, quite mess then I found I got compat-libsdtc++ and compat-libsdtc++-devel in rpm database. I thought they are installed by apt, so I try to remove them. Not successful. But adter, I cannot start mozilla. I see the network connection is there, I can ping other websites. I tried to reinstall mozilla, still not working. ANy help please? uegently!
