Installing Ubuntu One on Kubuntu 9.10

Canonical's version of Dropbox is called Ubuntu one. Although it is installed by default with Ubuntu 9.10, it is sadly missing from Kubuntu 9.10.

Issue the following commands inside a terminal:
echo 'deb karmic main' >> /etc/apt/sources.list
echo 'deb-src karmic main' >> /etc/apt/sources.list
sudo apt-key adv --keyserver --recv-keys 4427DF3B

Open KPackageKit and install the client: "ubuntuone-client-kde"

There should be a Ubuntu One icon in the start menu, under Applications, Internet. Click on the Ubuntu Icon.

To use: simply move files to the Ubuntu One folder that lives under your home folder.

Compiling Sportwatcher on Kubuntu

Sportwatcher is the Linux equivalent of the Garmin Training Center software. You can use Sportwatcher to sync your Garmin GPS watch without resorting to booting Windows in Virtualbox. Read more here...

I have compiled Sportwatcher 0.6 from source on Kubuntu netbook edition 9.10 Alpha 4 and these are my notes. Although you can install sportwatcher from .deb files I thought this post might be useful for somebody out there...

You can download the source from

Although there is a 0.7 source, I have problems compiling 0.7 - (I get Mapnik errors).

Step 1: Install compile utilities:

sudo apt-get install cmake build-essential apt-file

Step 2: Install dependencies for Sportwacther:

sudo apt-get install libgdal-dev kdelibs5-dev libusb-dev libmapnik-dev

Go make coffee - a lot of stuff will be downloaded. Once done, reboot - one of the components acts as a server and needs to be started.

Now we are ready to compile.

Step 3: Download source

- Download version 0.6 of Sportwatcher
- extract archive to any folder...
- open konsole (kde) and navigate to the extracted sportwatcher folder

Step 4: Compile

Issue the following command:

cmake CMakeLists.txt

if that was successfull then issue the following command:


If the compile was successfull, the executable will be in the src folder. The actual filename is called sportwatcher. You can then just click on the file while you are in the dolphin file manager (kde).

Problems and possible solutions:

If you run into errors while doing the cmake procedure which are usually dependency issues, two utilities that can help out are: apt-file and aptitude.

To install apt-file: sudo apt-get install apt-file. Then issue the following command apt-file update. You can use apt-file to figure out what package to install when cmake complains about a missing file. For example: when cmake complains about the following: ERROR: cmake/modules/FindKDE4Internal.cmake not found
Issue the following command:

apt-file search cmake/modules/FindKDE4Internal.cmake

Apt-file will then respond with "kdelibs5-dev". You can then install with:

sudo apt-get install kdelibs5-dev

Sometimes apt-file returns an empty answer. This is when you use the aptitude command for example:
cmake complains about cmake/modules/FindMapnik.cmake not found. Could not find Mapnik.
Issue the following command:

aptitude search mapnik

Look for a package that ends with -dev then install that package with sudo apt-get install ?????

Aptitude should already be on you system, so there is nothing to install to use it. Aptitude also comes with its own text based GUI - just issue the aptitude command without any parameters.
