How to Update, Share Folders, Share USB, Share Clipboard in Virtual Box

Описание: In this video I will be showing how to update Virtual Box without losing your snapshots, setup clipboard/drag & drop, how to share a folder, how to share a flash drive and how to install and run gqrx for SDRPlay. I will be showing all of these in real time, including How to Run EasyInstall.sh that I emailed you from the shared folder. I have the timeline below so you may jump to what you need.
I have also included the bash file for the EasyInstall.sh that I created.
Here is the link to creating a Ubuntu box and installing the OS (it starts at about 55 secs).

clear
echo "Easy install of gqrx for SFU-1"
echo "We need to get all of the dependancies first."
echo "We will be installing a number of packages. It may take a few minutes."
echo ""

Install the dependancies
sudo apt install git cmake build-essential gqrx-sdr cubicsdr libsoapysdr-dev soapysdr-tools gr-osmosdr uhd-soapysdr

clear
echo "We are now going to download and install the latest SDRplay API"
#Install the API - Make sure you have the correct file and version! You may need to change this filename
cd ~/Downloads
download the API from the SDRplay website
wget https://www.sdrplay.com/software/SDRp...
change the permission of the file to be able to install the software
chmod 755 ./SDRplay_RSP_API-Linux-3.15.2.run
execute the API installer (follow the prompts)
./SDRplay_RSP_API-Linux-3.15.2.run

clear
echo "We are now downloading SoapySDRPlay."
#Get the sdrplay soapy module and build it.
cd ~/Downloads
git clone https://github.com/pothosware/SoapySD...
cd SoapySDRPlay3
mkdir build
cd build
cmake ..
make
sudo make install

clear
echo "We are now going to download and install gqrx"
sudo apt update -y
sudo apt install gqrx-sdr -y
