I am using Ubuntu 14.04. I downloaded the Ubuntu version from this link:
virtualbox.org/wiki/Linux_Downloads
Ubuntu 13.04 ("Raring Ringtail") / 13.10 ("Saucy Salamander") / 14.04 ("Trusty Tahr") 64bit
download.virtualbox .org/virtualbox/4.3.18 virtualbox- .3_4.3.18-96516~Ubuntu~raring_amd64.deb
I installed by terminal:
wget -q https:// virtualbox .org/download/oracle_vbox.asc -O- | sudo
apt-key add -
Since it didn't work, I tried something else.
I downloaded the Windows version: virtualbox .org/wiki/Downloads
download.virtualbox .org/virtualbox/4.3.18/VirtualBox-4.3.18-96516-Win.exe
I installed it by using "Wine", and received this error:
Error window: SUPR3HardenedMain Effective UID is not root (euid=1000
egid=1000 uid=1000 gid=1000) (rc=-10) Please try reinstalling
VirtualBox.
Any other way to do it? I can't find why is not working!

Actually you install the package with:
sudo dpkg --install virtualbox-4.3_4.3.18-96516~Ubuntu~raring_amd64.deb

You can install virtual box from the ubuntu software center or
sudo apt-get install virtualbox-qt

I am new to Linux and I want to install .Deb software package in Linux. Let say I want to install chromex64.deb, how to install it? can anyone explain it?
You could try running dpkg -i chromex64.deb
If an error occurs saying that some dependencies are missing, install them using apt-get install
You can install by using dpkg -i command.
Navigate to download directory and open the terminal.
Run the following code:
sudo dpkg -i *.deb
If there is more deb file, specify the file name in place of *
If you find missing dependencies, you can try
sudo apt-get update --fix-missing

I'm new to Linux and I want to know how to install Node.js on Ubuntu 19.04.
I downloaded the node-v12.12.0-linux-x64.tar.xz from the website and extracted it, but I'm stuck after that, I don't know how to proceed.
I believe what you downloaded is the source for NodeJS (I could be wrong). So you'll need to build it yourself.
If you want to do that check this guide.
Otherwise you can check the NodeSource distributions repo on github.
For Node.js v12.x: run these commands in a terminal window
# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs
# Using Debian, as root
curl -sL https://deb.nodesource.com/setup_12.x | bash -
apt-get install -y nodejs

Hello Stackoverflow user,
I want to compile NWChem program on CentOS 7 and it requires an OpenBlas library. I have tried to install the OpenBlas via yum installer using command: yum -y install libopenblas or yum -y install libopenblas-devel.
Unluckily, it did not work and the error message is like there is no the openblas library in the repository.
Can anyone suggest me how to fix this issue?
Thanks a lot.
I am not 100% sure, but the correct package name should be openblas-devel.x86_64. Try the command yum install openblas-devel.x86_64 -y.

I am using a Linux server andtrying to install the jdk package. But when i try sudo apt , I get the following error:
sudo: apt-get: command not found
The version of Linux is:
3.10.0-229.el7.x86_64 GNU/Linux
Can't figure out whats wrong
It seems that you have CentOS on your server based on Linux version. You can try Yum instead. For example:
sudo yum install ...

I had 13.04 running fine although a bit slow, so I did
sudo apt-get install lubuntu
then restarted the computer
next, lubuntu opened, but it was terrible. The dock wasn't there, alt+tab and other window-control commands didn't work, and I couldn't search through the system for programs to open as I could before.
Surely all this can't be so difficult to reverse? All I did was one command.
Try this:
sudo apt-get remove --auto-remove lubuntu
Now you must switch your desktop environment. If you want ubuntu default desktop environment
sudo dpkg-reconfigure ubuntu-desktop
Or if you have KDE
sudo dpkg-reconfigure kubuntu-desktop
It's better to try dpkg-reconfigure before package removing.
