Updating to latest Boinc on Berkely site, Linux
I wanted to update Boinc to the latested stable one at Berkely so I could use the app_config.xml file as the latest Boinc from the Ubuntu repositories was 7.0.27 and I needed 7.0.40 at least to use it. While it is still fresh in my mind I thought I would document how I did it. I know D_A has given the directions to do it like this but I could not find it in the forums, so I thought it might be usefull with the renewed interest in Linux thanks to MMs adventures.

What you type is in bold text.
Install Boinc from repositories, if not already installed. If it is installed skip this part.

sudo app-get install boinc-client boinc-manager

Now stop boinc from running. When you installed it Boinc was started.

close Boinc Manager if open.

sudo service boinc-client stop

Download latest Boinc from Berkely to your $HOME directory.

In a Terminal window:
type cd and hit enter, this will put you in your home directory

NOTE: you do not have to type the entire file name. Type boinc_ and hit tab, it should finish the filename for you. If not type more of the name and hit tab until it does.

sudo chmod a+x boinc_7.0.65_x86_64-pc-linux-gnu.sh or what version you downloaded

sudo sh boinc_7.0.65_x86_64-pc-linux-gnu.sh again substitute the name of the file you downloaded

now cd BOINC the directory name should be all caps.

sudo cp boinc* /usr/bin/


sudo service boinc-client start
