Hello Linux Geeksters. As you may know, Teamviewer is a non-free software for remote control via the internet. The latest stable version available is TeamViewer 9, which has been released a while ago.

Among others, it comes with Wake-on-Lan support, two factor authentication for TeamViewer accounts, copy and paste support via clipboard, quick connections via desktop shortcuts, support for notifications, a redesigned interface, support for waiting connections in multiple tabs, a new feature that enables the users to perform file transfers without establishing connections, it got support for notifications and got enhanced video support. For a full list of features, see the changelog.
In this article I will show you how to install TeamViewer 9 on Ubuntu 14.04 Trusty Tahr, Linux Mint 17 Qiana, Pinguy OS 14.04, LXLE 14.04, Linux Lite 2.0, Deepin 2014, Elementary OS 0.3 Freya, Peppermint Five, Debian Jessie, Debian Wheezy, Kwheezy, Crunchbang and other Ubuntu and Debian derivative systems.
Because it is not available via PPA, we have to download the deb package from the official site and install it by hand. I prefer gdebi over dpkg due to the fact that it also handles dependencies. Follow the instructions for your system exactly, in order to get a successful installation.
How to install TeamViewer 9 on 32 bit Ubuntu, Debian and derivative systems:
$ sudo apt-get install gdebi
$ wget download.teamviewer.com/download/teamviewer_linux.deb
$ sudo gdebi teamviewer_linux.deb
How to install TeamViewer 9 on 64 bit Ubuntu, Debian and derivative systems:
Note: On newer 64-bit DEB-systems with Multiarch-support (Debian 7) teamviewer_linux_x64.deb cannot be installed because the package ia32-libs is not available anymore on these systems. In this case we have to use the teamviewer_linux.deb instead.
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install gdebi
$ wget download.teamviewer.com/download/teamviewer_linux.deb
$ sudo gdebi teamviewer_linux.deb
Optional, to remove remove teamviewer 9, on both 32 bit and 64 bit architectures, do:
$ sudo apt-get remove teamviewer
