If you are running Linux (in this case Ubuntu) - and want to use the Elecraft official update software this is how to get going.
Ubuntu 14 64 Bit install
This is starting from an Ubuntu 14 Workstation with only Python Dev installed on it.
mkdir kx3 cd kx3 wget http://www.elecraft.com/software/KX3/KX3UtilityLINUX_1_14_4_11.tgz tar -zxvf KX3UtilityLINUX_1_14_4_11.tgz cd kx3util_1_14_4_11
You can try and run it - but as I am on a 64 Bit linux this will fail (Yours will fail also)
./kx3util .... ./bash not found
32 Bit needed
So we need some 32bit libs...
sudo apt-get install lib32z1
Now try again
I see this
./kx3util ./kx3util: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
Ok - so we need that lib
sudo apt-get install lib32stdc++6
We try again
Now I get
Failed to find/load Framework library /home/tim/kx3/kx3util_1_14_4_11/./RBGUIFramework.so: cannot open shared object file: No such file or directory
I need to check what other libs are needed
ldd kx3util\ Libs/RBGUIFramework.so

Yikes lots of NOT Found ....
So more packages needed
sudo apt-get install libgtk:386
Now make a symbolic link (or Two)
ln -s kx3util\ Libs/RBGUIFramework.so RBGUIFramework.so
Cold Beer Time ?
And - cheers :)
