The new version of OpenCPN has only been out since February 3rd. It is not in the repository. They have not even updated their own website.

Sometimes it's best to let the dust settle before jumping in.
Changing the MAC address is relatively easy, for example
Code:
sudo macchanger -A wlan0
will assign a new MAC address to your
wlan0 interface.
The complication is you must know the name of your interface, as not all wifi is
wlan0.
From the terminal (
<ctrl><alt><t>) while your wifi is live
Code:
ifconfig
it will spit back a bunch of stuff
Code:
netty@netty:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 74:5a:34:cc:3d:e6

As you see I'm using the ethernet connection
eth0, and my wifi is
wlan0, but the process is the same for all MAC gizmos with the proper name.
The next thing is to shut down the interface to change numbers.
Code:
sudo ifconfig wlan0 down
Now you can change it.
Code:
sudo macchanger -A wlan0
then bring the interface back online.
Code:
sudo ifconfig wlan0 up
You could also install the GUI for this
Code:
sudo apt-get macchanger-gtk
which is nice, but it's not much easier.
The biggest problem is the current version of macchanger introduced a bug which that does not allow full 'random' MAC address assignment, but you should be able to live with that.
Code:
netty@netty:~$ sudo macchanger -A wlan0
[sudo] password for netty:
Current MAC: 78:e4:00:4c:2c:39 (Hon Hai Precision Ind. Co.,Ltd.)
Permanent MAC: 78:e4:00:4c:2c:39 (Hon Hai Precision Ind. Co.,Ltd.)
[ERROR] Could not change MAC: interface up or insufficient permissions: Device or resource busy
netty@netty:~$ sudo ifconfig wlan0 down
netty@netty:~$ sudo macchanger -A wlan0
Current MAC: 78:e4:00:4c:2c:39 (Hon Hai Precision Ind. Co.,Ltd.)
Permanent MAC: 78:e4:00:4c:2c:39 (Hon Hai Precision Ind. Co.,Ltd.)
New MAC: ec:2c:49:4c:2c:39 (University of Tokyo)
netty@netty:~$ sudo ifconfig wlan0 up
netty@netty:~$
If you want other options consult the manual
Code:
man macchanger
Good luck.
