+How to use multiple connections to speed up apt-get/apt on Ubuntu Linux 16.04 LTS server
+=========================================================================================
+
+ow do I speed up my apt-get or apt command to download packages from multiple repos on a Ubuntu Linux 16.04 or 14.04 LTS server?
+
+You need to use apt-fast shell script wrapper. It should speed up apt-get command/apt command and aptitude command by downloading packages with multiple connections per package. All packages are downloaded simultaneously in parallel. It uses aria2c as default download accelerator.
+
+### Install apt-fast tool
+
+Type the following command on Ubuntu Linux 14.04 and later versions:
+
+```
+$ sudo add-apt-repository ppa:saiarcot895/myppa
+```
+
+Sample outputs:

+
+Update your repo:
+
+```
+$ sudo apt-get update
+```
+
+OR
+
+```
+$ sudo apt update
+```
+
+![](http://s0.cyberciti.org/uploads/faq/2016/07/install-apt-fast-command.jpg)
+
+Install apt-fast shell wrapper:
+
+```
+$ sudo apt-get -y install apt-fast
+```
+
+OR
+
+```
+$ sudo apt -y install apt-fast
+```
+
+Sample outputs:
+
+
+```
