At first I got an error message,when I booted my system.
The system is running in low-graphics mode.Your screen, graphics cards, and input device settings could not be detected correctly. You will need to configure these yourself.
I pressed Ctrl +Alt+F1 and entered into terminal .Then I did the following commands.
sudo apt-get update
sudo apt-get remove ubuntu-desktop
sudo apt-get install ubuntu-desktop
sudo shutdown -r now
But after that ,even though error message was not showing when rebooted , my laptop's keyboard and mouse were not working.But external keyboard and laptop worked.My current Ubuntu version is 16.04 LTS.
Try installing the xserver-xorg-input-all package.
$ sudo apt-get install xserver-xorg-input-all

I have installed anaconda on my kali linux OS. I am getting Rstudio as an option to install on navigator but when I click on it, it just loads and there is no progress. I even used terminal to do so, but it just points out some problems and is unable to fix it. I can't even find an option on Rstudio website to install for kali linux OS.
Use the following command to install Rstudio on Kali linux:
sudo apt update<br>
sudo apt -y upgrade<br>
sudo apt -y install r-base<br>
wget https://download1.rstudio.org/desktop/debian9/x86_64/rstudio-1.2.5042-amd64.deb<br>
sudo apt install ./rstudio-1.2.5042-amd64.deb<br>
If you encounter any dependency problems, run:
sudo apt -f install
For starting Rstudio, run:<br>
$ rstudio

i want to install virtual box on mac os EI Captain with homebrew and also if i want to install more packages with homebrew how can i know that package is available in homebrew?
Thanks
First, you’ll need the command-line tools for Xcode installed. On a modern Mac OS X system, you can install these just by running the following command in a Terminal window. You could also install the full Xcode application from Apple, if you prefer — but that takes up more space on your Mac and isn’t necessary.
xcode-select --install
Next, install Homebrew. You can just open a Terminal window, copy-paste the following command, and press Enter:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
This script informs you what it will do. Press Enter and then provide your password to install it. By default, it installs Homebrew so you can use the brew command without typing the sudo command and providing your password.
Run the following command once you’re done to ensure Homebrew is installed and working properly:
brew doctor
Once you’re done, run the following command to install Homebrew Cask. It uses Homebrew to install Cask:
brew install caskroom/cask/brew-cask
Now you can install the Virtual box by entering the following commands
brew install vagrant-completion
brew cask install virtualbox
brew cask install vagrant
brew cask install vagrant-manager
For knowing that your package is available or not you can search your desire package by the following commands
For Open-Source Utilities
brew search name-of-your-package
For graphical Apps
brew cask search name-of-your-app
For installing Graphical Apps run
brew cask install name-of-your-app
For installing Open-Source Utilities run
brew install name-of-your-package

sudo apt-get install virtualbox

.
you have to enable Intel VT-x or AMD-V virtualization hardware extensions in BIOS. By default it is disabled.

I want to install Rstudio for ubuntu, so I used the link https://www.rstudio.com/products/rstudio/download/ after that I choosen RStudio 0.99.893 - Ubuntu 12.04+/Debian 8+ (64-bit) then I opened with Ubuntu software center. In that I clicked the install button I got error box like this,
Requires installation of untrusted packages
This requires installing packages from unauthenticated sources.
How to solve this problem?
The unauthenticated package required by RStudio is libjpeg62, so install the package separately and then install rstudio from software center
In the terminal run the following for installing libjpeg62
sudo apt-get install --allow-unauthenticated libjpeg62
Then go back to installing rstudio.
Note: you need to install r interpretor along with rstudio this you can do by following
sudo apt-get install r-base
# Install R and RStudio on Ubuntu 14.04
sudo apt-get update
sudo apt-get install r-base
sudo apt-get install r-base-dev
# Download and Install RStudio
sudo apt-get install gdebi-core
wget https://download1.rstudio.org/rstudio-1.0.44-amd64.deb
sudo gdebi rstudio-1.0.44-amd64.deb
Runs following commands :
In order to install RStudio on Ubuntu 18.04 we will first need to install the r-base package. Open up terminal and enter:

I was trying to install Firefox 5 using these commands -
sudo add-apt-repository ppa:mozillateam/firefox-stable
sudo apt-get update
sudo apt-get upgrade
The upgrade was happening, but I accidently killed the process, and Firefox 5 was up, so I didn't bother then. But the next time I restarted the system, I was stuck at the login screen. How can I recover it ?
You might have some broken packages. To check, press CTRL-ALT-F1 to go into TTY1 (note: CTRL-ALT-F7 gets you back to the GUI) and login using your credentials.
Now, run:
sudo apt-get install -f
It should give you more info about what's wrong.
Because you didn't provide any error logs or anything, we can't help you much...
