still new to Linux and trying out Ubuntu. Was able to get it installed however when I tried updating in terminal with $sudo apt-get update I would get the following:

wave@Wave:~$ sudo apt-get update    
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)   
E: Unable to lock directory /var/lib/apt/lists/   
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)  
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

sudo lsof /var/lib/dpkg/lock (man lsof) will show all processes that have the file open. On my system (YMMV), with synaptic running: 

$ sudo lsof /var/lib/dpkg/lock
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
