Guide: Install Technic Launcher on Linux mint 17/Ubuntu 14

[Unio]

Guide to install and run the Technic Launcher in Linux Mint 17/Ubuntu 14:

Q: Why is this guide necessary?
A: Because I've had difficulty finding a guide online that actually worked. And I want to share my solution with the community.

Tip: Copy the commands one at the time, and middle click/mousewheel click in Terminal to paste.

Step 1: Uninstall Java, to make sure you get the correct Java version installed.
Run the following in Terminal:
sudo apt-get-purge openjdk*

Step 2: Install Oracle Java 7.
Run the following commands in Terminal:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Step 3: Download Technic Launcher.
From http://technicpack.net/download click on the 'Linux' button, and download the .jar file.

Step 4: Move the .jar file to where you want the Launcher to be. I'd recommend Desktop.
Don't worry. You'll get to pick where to install the Launcher later.

Step 5: Allow the .jar file to run as a program.
Right click the .jar file > Properties > Permissions
Make sure the box is ticked next to 'Allow executing file as program'
Don't close the properties window.

Step 6: Make the .jar file run in Java.
If you've closed the properties window, see Step 5.
Go to Properties > Open With
Scroll down the list, until you find 'Oracle Java 7 Runtime'
Click on 'Oracle Java 7 Runtime' and set as default.
You can now close the Properties window.

Step 7: Install the Launcher.
It should be as simple as a doubleclick on the .jar file.
Just follow the instructions.
When the Launcher loads, close it again.
Now you should be good to go.

Step 8 (Optional): Rename and choose a new icon for the Launcher.
Right-click the .jar file > Properties > Basic
To rename the file, just edit the text.
To choose a new icon, click on the icon to the left.
If you don't already have a path to your icon of choice, open 'Home' and navigate to the folder containing the image. Then copy the path.
Now follow Step 8.
Paste the path as location, and choose your new icon and click Open.


Now you should have a working Launcher, with custom icon and name.
Enjoy.

Why would you recommend users to install Java 7 instead of Java 8? Java 8 works fine for all modpacks and is the standard towards which Mojang is pushing folks.

If you've been using Linux for any amount of time, you should know how to do all of this, thus making guides for such a thing unnecessary... Probably why you've had trouble finding one.

Hi,

I am very new to Linux, and am currently running mint 17.1. I believe I installed java right, when I type java -version it displays

java version 1.7.0_79

OpenJDK Runtime Enviroment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2) 

OpenJDK 65-Bit Server VM (build 24.79.b02, mixed mode)

which, to my incredibly finite knowledge seems ok. However I am caught on step 6, as there is no Oracle Java 7 Runtime option. The closest option I could find was IcedTea Java Web Start, which does not work to run technic launcher, saying it could not parse the JNLP file. I have no idea what aspect I went wrong in, if you need more info to help diagnose the issue, just let me know.

Cheers

I think I followed the steps all right, but when  I start the  program its starts off just a white box. Then when I click around it only loads the things that I can click.

Also, when I try to type my username and password it says there wrong. When I know there right.
