problem ubuntu software center,linuxdcpp
i've been using ubuntu9.10 since 1 month.
But recently due to some error in installation of google desktop(package is partially installed),The package installer is giving the error that there is already a
program running in software center/synaptic package manager,so it cant install any package.
when i try to install anything through software center it is telling that"waiting to other software managers to quit".
also linuxdcpp is very slow and is very often getting struck.
i cant give this wonderful os for these two resons.please help me.
