Installing Debian packages (Automatic Script)

SEELablet packages will be available in the nextDebian release , but for now the packages can be automatically set-up using the following script

URL='https://drive.google.com/uc?export=download&id='
LIBNAME='0B2o9AyrvXHPYZ1FaYlJXTGFBTjg'
APPNAME='0B2o9AyrvXHPYUEEtM3pVSzJKSE0'
wget $URL$LIBNAME -q --show-progress -O lib.deb 
 
if wget $URL$APPNAME -q --show-progress -O apps.deb ; then
	echo "Fetched Apps... removing previous installation"
	sudo apt-get remove -y libseelablet
	sudo rm -rf /usr/lib/python2.7/dist-packages/SEEL*
	sudo rm -rf /usr/share/seelablet/

else
    echo "Fetching Apps Failed"
fi

sudo gdebi --n lib.deb
rm lib.deb

sudo gdebi --n apps.deb
rm apps.deb

Create an empty file called install.sh in the home folder, and copy the contents of the above script into it

Open a terminal, and execute the following commands.

sudo chmod +x install.sh
sudo apt-get install gdebi
./install.sh

This automatically downloads the source packages as well as associated dependencies
