First, run the following command to add the Dropbox repository.
sudo add-apt-repository "deb http://linux.dropbox.com/ubuntu $(lsb_release -sc) main"
Next, run the command sudo apt-get update. You should get an error message
similar to the following:
W: GPG error: http://linux.dropbox.com precise Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY FC918B335044912E
Follow the instructions at
http://reprogrammer.github.io/faq/2013/02/24/how-can-i-install-ubuntu-repository-public-keys/
to add the necessary keys. While following the instruction, note that the
Dropbox’s key server is pgp.mit.edu.
Finally, run the following commands to install Dropbox.
sudo apt-get update
sudo apt-get install dropbox python-gpgme
The command sudo apt-get update reports the following problem:
W: Duplicate sources.list entry http://linux.dropbox.com/ubuntu/ precise/main amd64 Packages (/var/lib/apt/lists/linux.dropbox.com_ubuntu_dists_precise_main_binary-amd64_Packages) W: Duplicate sources.list entry http://linux.dropbox.com/ubuntu/ precise/main i386 Packages (/var/lib/apt/lists/linux.dropbox.com_ubuntu_dists_precise_main_binary-i386_Packages) W: You may want to run apt-get update to correct these problems
I need to figure out how to resolve the duplicate entry problem.
