yes i find something , in the section step 2 .for Debian Packages (Ubuntu) i suggest to install the gridcoinresearch-qt not gridcoinresearchd.
it is
sudo add-apt-repository ppa:gridcoin/gridcoin-stable
sudo apt-get update
sudo apt-get install gridcoinresearchd
gridcoinresearchd for headless client
but we need
sudo add-apt-repository ppa:gridcoin/gridcoin-stable
sudo apt-get update
sudo apt-get install gridcoinresearch-qt
gridcoinresearch-qt
Yeah, it depends on what software you want installed - headless or qt.. I should perhaps expand on that, but then I'm not expanding on instructions for the other distros (Arch/Suse)..
Duly noted though, thanks :)
