I successfully update/install the latest version of node js by using those commands (the official curl way not working for me) :

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/node

However, the version of my node and nodejs become different :

$ node --version
v5.0.0
$ nodejs --version
v0.10.25

It seems the new node is installed in /usr/local/bin/node, so i tried :

sudo ln -s /usr/bin/nodejs /usr/local/bin/node

But it returns :

ln: failed to create symbolic link ‘/usr/local/bin/node’: File exists

I also use this link :

$ sudo ln -s /usr/bin/nodejs /usr/bin/node
ln: failed to create symbolic link ‘/usr/bin/node’: File exists

I will use some frameworks that depend on node, like Ionic. Which node version will it use?

What should i do to solve this?

Thanks a lot for your help

I have been working an hour for this.

Taken from their official documentation :

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

However, its never working for me. I have tried to clear the npm cache, even uninstall it and run both command again. Its still not working. I keep getting version 0.10.25

I run :

grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* 

And this is what i get :

What should i do? Please kindly help me

This question is related to my other question : Full dark theme for eclipse Luna in Ubuntu 14.04

So, i should run export SWT_GTK3=0 on a sh script for eclipse, but i mistakenly run it from my ubuntu's terminal.

I dont feel something changed for now, but i would like to make sure my system will be OK since i will need it in the near future.

Does running export SWT_GTK3=0 dangerous?

What does it do?

How to reset SWT_GTK3 to its default value?

Thanks a lot for your time.

I read this question : Why is Eclipse Luna dark theme ugly?

And i followed what guari told us to do. I create a dark.sh in a same directory with eclipse executeable. This is the code :

#!/bin/bash
export SWT_GTK3=0 //0 or 1 not working
./eclipse

So i run the dark.sh from the terminal, and eclipse will be run from it. However, my side bar is still looking ugly (white, not dark).

What should i do?

UPDATE

I use dark theme (default from the eclipse)#!/bin/bash

export SWT_GTK3=0
export UBUNTU_MENUPROXY=0
./eclipse

But it still not working.

Thanks for your help.

This seems basic & easy, but man...i got headache here.

I followed this question : How to save php file in /opt/lampp/htdocs without going to terminal and type sudo gedit?

I want to be able to do copy-paste to the /opt/lampp/htdocs. This is what i did on terminal :

1. See current user & group : users -> result : tama tama

3. sudo chmod 700 /opt/lampp/htdocs

The owner of the files has changed successfully, but i still cant do paste there. (greyed out)

If i remember correctly, i dont do anything with python library. I did some googling and people said to do apt-get update & upgrade. I tried them, but no luck.

UPDATE

I tried to reinstall python & software-center using :

sudo apt-get install --reinstall python2.7
sudo apt-get install --reinstall software-center

But the error still persists

Thanks for your time.

First, sorry for the silly question. I did some googling, but still not quite sure the answer.

I dont want to upgrade my ubuntu to 14.10 because its not LTS. However, i want to do some upgrades other than the OS.

Is it safe to use dist-upgrade?

I know dist-upgrade will upgrade the kernel, does it means it will also upgrade the ubuntu version?

I havent used my Ubuntu for quite a long time. Today, when I booted Ubuntu (14.04 LTS), the software updater and Software & Updates (from Settings) are not working.

The software updater's window will show up for around 1 sec, but it will close automatically. Software & Updates is never shown, no matter how many times I click the icon. Note that neither of them show any error message.

Those 2 features were working perfectly the last time I used Ubuntu. I want to do some system upgrade and update.

For now, I use sudo apt-get update && sudo apt-get upgrade. This command runs very fast, meaning (I think) my Ubuntu is not updated properly. The update from software updater always has a big size hence the download should be slower.

What should I do?

Can I just uninstall and reinstall both of them? If I can, how to do it?

Just to clarify, I don't want to upgrade my Ubuntu version (I want the LTS one), I just want to upgrade the software/packages I used.

Thanks for your time.

I have a simple question coming from my mind.

What is the difference between :

sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle

And simply

sudo apt-get install gradle

Which one should i use & why?

Thanks for your time.

I have a dual-boot machine. The internet is perfectly fine when I use Windows; I can access all websites normally.

However, when I change to Ubuntu, I can no longer access Facebook, Twitter, YouTube, etc.

What is going on? What should I do to get this fixed?

I'm experimenting with some download managers on Ubuntu, and I think uget + aria2 is very good in terms of speed.

So I decided to make a queue and download those files using uget, with aria2 plugin enabled. However, the queue is not auto-downloading, ie the downloading stops after one file finishes. It should go to the next download automatically.

Note: What I want is to download a queue one by one (so I change the active download to one, one file at a time), not download them all at the same time.

This is the first time i use wget so please bear with me.

I have flareget installed on my ubuntu, but i decided to try the famous wget. I have no when using flareget, but my wget is not working.

I was trying to download a movie from putlocker, it could be downloaded from flareget but not wget. This is the error on the terminal :

HTTP request sent, awaiting response... 301 Moved Permanently
Resolving www. (www.)... failed: Name or service not known.
wget: unable to resolve host address ‘www.’

And this is the movie's url in case it has any effect :

http://media-b158.putlocker.com/download/15/64/42195d9d2e746f82cecd4eaebe80e0be?h=v0_gBTTgGzNSJEMi0T4y5A&e=1388834376&f=Ipman.sidofi.com.mkv.rar&domain=putlocker.com

I do not use the hyperlink because i think you just want to see the url, and the url seems only working on my IP.

Any help is appreciated, Thanks for your help .

I'm new in ubuntu so please bear with me.

I need to create a C based program for a course in my university. I was using openSUSE as the OS and konsole as the terminal emulator when I was in the university's lab.

So basically I need to install openSUSE on my system or use a VM to do so. But i feel lazy to do that, so I tried to run it on my Ubuntu instead of openSUSE.

However, no C code seems working on Ubuntu's terminal. The compiling is success, but its not running, or at least the printf is not running.

This is my code, a very very simple one :

#include<stdio.h>
#include<unistd.h>
#include<stdlib.h>

int main()
{
    printf("test");
    return 0;
}

When I compile it with gcc test.c -o test everything works fine and i get an executable file.

Then I try to run it by ./test, but the printf is not printed. No error or warning was shown.

Am I missing something?

Note : my gcc is the new one, it should has no problem.

First, im new on linux so please bear with me.

I have a rooted android phone and i was able to run the adb via wifi network on windows, where i just need to go to the adb's directory and type adb connect.

However, i can't just do that in my ubuntu. Everytime i enter adb connect, the terminal always said that i dont have the adb and i must install it. When i check the ADT Bundle (I downloaded the bundled one from here), i can see the adb is there inside the platform-tools folder.

I already tried to change the directory to the platform-tools and run the adb connect from there, but its still not working.

Do i need to install the adb again via terminal? Or did i miss something?

You may be wondering why dont i just download the adb (again) via terminal and do trial and error? The answer is because i dont have a good internet connection, so i want to avoid unnecessary downloads.

Thanks for your time :D

My firefox used to be working normally for the first time i installed ubuntu 13.04. I dont feel did anything wrong, but it suddenly cant be opened via the launcher. When i tried to type "firefox" in the terminal, it shows the very same error like this question.

So, i followed the answer in that question, and voila...its working now :D

However, something is still bothering me. Why is this happened suddenly? The fact that i used chown to make it works again means that the owner of the firefox is changed.

And why this message is still appearing in the terminal although the firefox is working now : GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

Thanks for your time :D

First, im new to Ubuntu so please bear with me.

My Google Chrome shows strange behavior when playing Youtube videos in full screen mode. There will be some horizontal white lines, which is exactly like when you are playing the game without the vsync.

I've checked Firefox and the videos working perfectly in there. I also tried to play videos from my HDD using VLC player and its working fine. It seems the problem is in the Google Chrome alone.

My version of ubuntu is 13.04, my laptop is asus n46vz and i use the latest release of Google Chrome.

I've tried to ask Google, but it seems they have no answer.

Thanks for your time :D

Im using ubuntu 13.04 and i just installed lampp. Now i want to copy a file to opt/lampp/htdocs. I also cant create new folder and documents in this location.

When i see the properties of a file, it said "you are not the owner, bla bla", and i cant edit the "Access" drop down list. What is going on? What should i do?

Thanks for your time :D

First, im new in ubuntu so please bear with me.

I've installed xampp for linux (lampp), and now im trying to get its UI (like windows) by following this guide

I've successfully followed the guide, until the final step that i must open the xampp in Application>>> Others.

Where is this application/others folder? I tried to find it and do some googling but i still cant find it.

Thanks for your time :D

I'm new to ubuntu (but i like it a lot), so please bear with me.

I want to install Java, but which one should I install?

• The RPM or the normal one?
• 32bit or 64bit?

From what I know, even windows 64 bit is still using java 32 bit. This thing make me confused.

I'm asking here just to make sure everything is going to be all right, because I will need my system to be ready to code (eclipse :D) pretty soon, so I want to avoid any trouble now.

Thanks for your help, and sorry for my basic question.
