Installation of BURAI in Ubuntu 18.04/20.04 LTS
Dear Readers,
Today you will learn how to install BURAI a Quantum Espresso GUI package in Ubuntu.
Before that, I have a suggestion for you "Always use an LTS (Long Term Support) version of Ubuntu in your system." So that you can finish your research easily without spending your time in updating the unstable versions of Ubuntu and sometimes it is difficult to install some applications in "odd" versions of Ubuntu.
Note: LTS versions are released in every "even year in the month of April" eg. 16.04, 18.04, 20.04. here 16,18 and 20 denoting the year and 04 the month.
Now let's start the installation.
Step-1: Download the latest version of the java development kit (JDK) and BURAI
Note: to download java you have to create an account at oracle first.
For java go to this link: Java JDK
For BURAI go to this link: BURAI
Download the installation script: install.sh
Step-2: Remove the existing version of java
sudo apt-get purge openjdk*
sudo apt-get purge
sudo update-alternatives --remove "java" "/opt/jdk/jdk1.8.0_261/bin/java"
sudo update-alternatives --remove "javac" "/opt/jdk/jdk1.8.0_261/bin/javac"
sudo apt autoremove
sudo apt-get update
Step-3: Installation of Java
sudo mkdir -p /opt/jdk
sudo cp ~/Downloads/jdk-8u261-linux-x64.tar.gz /opt/jdk/ # your java file should be in "Download" directory
cd /opt/jdk
sudo tar zxvf jdk-8u261-linux-x64.tar.gz
sudo update-alternatives --install /usr/bin/java java /opt/jdk/jdk1.8.0_261/bin/java 100
sudo update-alternatives --install /usr/bin/javac javac /opt/jdk/jdk1.8.0_261/bin/javac 100
java -version
