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
|
|
```
|
|
|
|
|
|
|
|
Install apt-fast shell wrapper:
|
|
|
|
```
|
|
$ sudo apt-get -y install apt-fast
|
|
```
|
|
|
|
OR
|
|
|
|
```
|
|
$ sudo apt -y install apt-fast
|
|
```
|
|
|
