Revover Encrypted Home Directory – Ubuntu 11.04 live
June 19, 2011 | 
Author I am having some problems with my hard-drive, so I was trying to backup my data the reside on my encrypted (the default Ubuntu encryption) home directory.
Ubuntu 11.04 offers a command (ecryptfs-recover-private) that help you perform this operation easily. Simply follow the steps:
- Boot Ubuntu 11.04 with a live-cd or usb.
- Mount the partition that includes the encrypted directory. You can easily do this by selecting
Places -> PartitionName. - Open a terminal (
Applications -> Accessories -> Terminal). - Run
sudo ecryptfs-recover-private
You will be prompted to enter the password that corresponds to the user of this partition. After this, the partition should be mounted at a folder indicated by the output of the command.

Netbeans 7.0 on Ubuntu Installation – OpenJDK problem
Installation
The installation process is simple:
- Download the version you want to install from here.
- Navigate to the folder were the
.shfile was downloaded. - Give executable permissions to the
.shfile. - Execute the installer (
.sh) file either pretendingsudocommand (in order to install it in the default/usr/local/netbeans-7.0location) or without (in order to install it in the/home/Username/netbeans-7.0/location) - Use the Graphical Installer to do the installation.
For example:
[~] $ cd ~/Desktop/ # Step 2 [~/Desktop] $ ls -l netbeans-7.0-ml-cpp-linux.sh -rw-r--r-- 1 *** *** 45967360 2011-05-03 09:21 netbeans-7.0-ml-cpp-linux.sh [~/Desktop] $ chmod +x netbeans-7.0-ml-cpp-linux.sh # Step 3 [~/Desktop] $ ls -l netbeans-7.0-ml-cpp-linux.sh -rwxr-xr-x 1 *** *** 45967360 2011-05-03 09:21 netbeans-7.0-ml-cpp-linux.sh [~/Desktop] $ sudo ./netbeans-7.0-ml-cpp-linux.sh # Step 4 Configuring the installer...

OpenJDK Problem
The problem with OpenJDK
Configuring the installer... Searching for JVM on the system... Extracting installation data... Running the installer wizard... null |
while installing Netbeans 6.9.1 on Ubuntu is the same for Netbeans 7. Netbeans needs Sun JDK to work, otherwise even the installation wizard (GUI) does not appear.
Read more details about the problem and how to solve it in the post about Netbeans 6.9.1.
Netbeans 6.9.1 on Ubuntu 10.10 Installation – OpenJDK problem
I wanted to install Netbeans IDE 6.9.1 (C/C++ version, but I believe that the problem is generic) on my Ubuntu 10.10 laptop, so after downloading the latest version from netbeans.org, I tried to install it:
$ ls -l netbeans-6.9.1-ml-cpp-linux.sh -rw-r--r-- 1 ** ** 36699136 2011-02-06 00:58 netbeans-6.9.1-ml-cpp-linux.sh $ chmod +x netbeans-6.9.1-ml-cpp-linux.sh $ sudo ./netbeans-6.9.1-ml-cpp-linux.sh |
and got the following output:
Configuring the installer... Searching for JVM on the system... Extracting installation data... Running the installer wizard... null |
The installation wizard (GUI) did not appear at all.
Luckily, I “immediately” thought “hmm, I re-installed Ubuntu quite recently, did I install JRE?”
So, I checked if I had “Java” installed and checked that everything is “good”:.
$java -version java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.5) (6b20-1.9.5-0ubuntu1) OpenJDK Client VM (build 19.0-b09, mixed mode, sharing) |
As you can see, I had OpenJDK installed..
For some reason, which I don’t know, I had already installed the Sun JDK, but not removed the OpenJDK, or at least set the java to point to the Sun version.
So, using synaptic, I unistalled OpenJDK (you can (un)install OpenJDK and Sun JDK from the Software Center also):
$java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode) |
And then, everything worked fine..
