Upgrading to Ubuntu 14.04 LTS

Ubuntu 14.04 “Trust Tahr” is released and It’s time to upgrade.

Step 1. Backup

Backup all the important files/configs/ etc. The upgrades usually go smooth but that doesn’t mean you shouldn’t have backup ready, in case anything goes wrong.

Step 2. Disable proprietary drivers

Remove proprietary binary drivers for graphic cards (Nvidia/AMD) etc as the linux kernel version will change in 14.04, the older graphic drivers may not work. So, it’s better to uninstall them before upgrade and reinstall after upgrade. And reboot the system.

Step 3. Start Update manager

From Ubuntu 13.10, it should be available in update manager. Just type

sudo update-manager

and follow the upgrade instructions.

From Ubuntu 12.04 LTS, you need to provide -d option for force upgrade (until, it’s officially available in next few months (until 14.04.1), by July/Aug 2014) :

sudo update-manager -d

And you should see 14.04 available in update manager.

update manage ubuntu 14.04

Click on “upgrade” and follow the instruction. And of course, you should reinstall any proprietary drivers if removed earlier.

Note : If you don’t see the message “New Ubuntu Release ‘14.04’ is available”, then you may need to check settings and enable the option that says : notify me about new ubuntu version for long term support version.

Ubuntu 14.04 LTS is released!

Ubuntu 14.04 (code named as Trusty Tahr) is released.  It’s a LTS release, so, it will be supported for next 5 years (the earlier LTS edition (12.04) was released two years ago). If you move from LTS to LTS (as I do, for primary development environment), then it’s time to upgrade.

What’s new in Ubuntu 14.04 “Trusty Tahr” ?

In the latest Ubuntu 14.04 Desktop edition, the default desktop environment Unity has improved a lot. Now, you can easily change menu bar settings to windows title bar instead of top menu bar, It also supports  high DPI screens and text scaling as well, Improved screensaver and locked screen etc.

So, before switching to alternate desktop environment like Mate/Cinnamon or GNOME, you should give it another try. You may like it. Although, new version of GNOME (3.12) will also be available soon.

Here are some other changes/improvements in this new release.

  • Ships with Python 3 by default, although you can easily install python 2 from the package
  • Linux Kernel 3.13
  • Updates and new features for AppArmor
  • Newer version of Upstart (1.12.1)

Ajenti – Awesome and easy server administration frontend!

Ajenti is a server admin panel program for web administrators. It’s available for Debian (or its derivatives such as Ubuntu), Arch, CentOS, FreeBSD, Gentoo etc. Most of the server administrators prefer command line, that’s usually fast and efficient for setup and deployment, but for monitoring servers, it would be lot easier to use an admin panel like Ajenti, especially if you’re not very good at commands.

Ajenti provides a very nice and easy to use Dashboard for monitoring and controlling servers, you can check resource usages (RAM, CPU graphs and reports), configure firewall, DNS, check logs, install/update packages, analyse network status, create/remove cron jobs, recovery/backup settings and a lot more things (just install the plugins you want to use). It basically provides an elegant GUI for managing servers, in a very easy way. You would probably feel like – using a desktop environment, specifically designed for server administration.
