Some Applications and Troubleshooting for Ubuntu 12.04

1. Installing dropbox in Ubuntu 12.04

                 Dropbox installation is not as easy for users behind a proxy. Two major problems seen during dropbox installation are:

(i) If dropbox is installed from repositories using apt-get or synaptic or usc, usually a screen appears asking for permission everytime we launch dropbox and most of the times it doesnt launch.

(ii)Drobox deamon fails to download and install automatically after dropbox installation.

                       The dropbox installation can be easily done as follows. Instead of installing dropbox available in repositories go to dropbox website. Download dropbox for ubuntu 64 bit or 32 bit.Now install this by opening in ubuntu software center or using the following commands:

sudo dpkg -i

sudo apt-get -f install

While launching dropbox it will try to download and install the daemon. It will show connection problem if you are behind a proxy. Close the dropbox and run the following command in terminal.

32-bit:

cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86" | tar xzf -        

64-bit:

cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf - 

 Now you can launch dropbox and the account and proxy details can be entered.

2. Download Manger for Ubuntu (with some features of IDM)

                      Windows users are blessed with a great Internet download Manager. But there is no linux version for this. Also there is  great difficulty in installing IDM via wine. The best download manager availabe for linux is prozgui. It can be installed by adding ppa by typing the following command in the terminal:

sudo add-apt-repository ppa:alza/project
sudo apt-get update
sudo apt-get install prozgui

For users behind a proxy it may be difficult to add ppa. It can be installed by manually adding the following lines to /etc/apt/sources.list

deb http://ppa.launchpad.net/alza/project/ubuntu precise main
deb-src http://ppa.launchpad.net/alza/project/ubuntu precise main 

The signing key is available to remove GPG errors.

Now run the following commands in terminal to install.

sudo apt-get update
sudo apt-get install prozgui

In the prozgui  prefernces panel the number of threads can be increased up to 30. In proxy tab the proxy server details can be entered.

The prozgui doesn't get  integrated to browser. For firefox flashgot add-on can be used for this purpose.
