Hello Linux Geeksters. As you know, Opera is a popular web browser, available for Linux, Mac OS X and Windows. Last year, Opera has adopted Google’s forked WebKit engine, the new versions of the browser being based on Chromium. After the release of Opera 12.16, the Linux support has been dropped, until Opera 26 Dev has been released for Linux.

The latest version available is Opera Developer 29.0.1770.1, based on Chromium 42.0.2287.0. Among others, it includes 220 changes and new features, including a feature that lets the users to sync the open tabs between multiple devices and sound notification icon on tabs. By having this feature, the users can resume their work from where they had left it very easy, by accessing the Recent Tabs feature, or the History, on Linux systems.
The tabs that play audio and video streams have a small animation over the favicon, letting the users identify the noisy tabs.
In this article I will show you how to install and test Opera 29 on 64 bit versions of Ubuntu 14.10, Ubuntu 14.04 Trusty Tahr and derivative systems: Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, Peppermint Five, Linux Lite 2, LXLE 14.04 and other Ubuntu 14.04 derivatives.
Because the developer branch of Opera is not available via any repository, we have to download the Opera 29 deb package from the Opera pool and install it via command-line. I prefer gdebi over dpkg, due to the fact that it also handles dependencies.
How to install Opera Dev 29 on 64 bit Ubuntu 14.04 and derivative systems:
$ sudo apt-get install gdebi
$ wget http://get.geo.opera.com/pub/opera-developer/29.0.1770.1/linux/opera-developer_29.0.1770.1_amd64.deb
$ sudo gdebi opera-developer_29.0.1770.1_amd64.deb
Because the Opera 26 deb package gets updated frequently, most likely version 25 will be replaced by a new one soon, so when this link becomes obsolete, download the deb for amd64 Ubuntu systems from HERE and install it via gdebi.
Optional, to remove opera, do:
$ sudo apt-get remove opera
