Oracle Java 8 on Ubuntu 14.04 / Mint 17.3

Leave a comment

Default “Java” version of Mint Linux 17.3 (or Ubuntu 14.04) is OpenJDK 1.7 which works fine, but some SDKs won’t install until you upgrade to 1.8 (for example Tizen IDE studio complains on OpenJDK 1.7)

Before you start, check the current version with “java -version”

java version "1.7.0_121"
OpenJDK Runtime Environment (IcedTea 2.6.8) (7u121-2.6.8-1ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

Add the PPA, update and install oracle-java8-installer

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

(During the install process you’ll need to accept the Oracle terms)

Now, check again with “java -version”

java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

In case you’re still receiving the 1.7 versions as response, install “oracle-java8-set-default” package with

sudo apt install oracle-java8-set-default

and check again.

Laravel 5.x requires PHP version 5.5.9+. Also, in case you want to use database (sqlite or mysql), install Sqlite3, Mysql or PostgreSQL server.

Install composer with

curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

Install Laravel (option 1)

composer create-project laravel/laravel laravel-test

Instal Laravel (option 2)

composer global require "laravel/installer=~1.1"

Add the following to .bashrc file

export PATH="~/.composer/vendor/bin:$PATH"

at the end of the file then in terminal type

source ~/.bashrc

and verify that $PATH variable contains the full path to laravel executable.

Then create new Laravel project with

laravel new laravel-test

Mint Linux Cinnamon – Invisible menu text on Netbeans

4 Comments

I noticed one bug with Mint Linux (Cinnamon) and Netbeans menu items that have an ‘active’ state which are completely invisible. Actually the text and the background colors are the same.

Mint 14 Nadia Cinnamon and later versions are affected (LMDE also) with NetBeans 7.3 and later.

The problem lies in the Mint-X GTK theme. To fix this problem, you need to modify /usr/share/themes/Mint-X/gtk-2.0/Styles/menu.rc file and lines

fg[ACTIVE] = @selected_fg_color

should be replaced with:

fg[ACTIVE] = @menu_fg_color

There are two lines (in style “menu” and style “menubar”)

Edit: 7. Aug. 2014.

The notes shown above doesn’t work on Mint 17 and it seems that Marco Moreno solved this problem

According to https://bugs.launchpad.net/linuxmint/+bug/1163030, you’ll need to change the /usr/share/themes/Mint-X/gtk-2.0/styles/menus.rc file.

Change line 53 from:

fg[ACTIVE] = @base_color

to:

fg[ACTIVE] = @fg_color
