How to Manually Install Security Updates on Debian/Ubuntu?
|
||||
======
|
||||
|
||||
Installing a package in Linux from command line is a simple task.
|
||||
|
||||
In a single command or combining of multiple commands could make you to complete your task easily.
|
||||
|
||||
The same can be done for security updates as well.
|
||||
|
||||
In this tutorial, we will show you how to check available security update and install them on Debian based systems such as Ubuntu, LinuxMint, etc,.
|
||||
|
||||
It can be done using three methods. All these methods are described in this article in details.
|
||||
|
||||
As a Linux administrator, you should keep your system up-to-date, that makes your system more secure. It protects your system against unwanted attack.
|
||||
|
||||
If you are not able to patch entire system with all updates due to some application dependency. At-least, you should install only security patches to make your system 100% compliance.
|
||||
|
||||
### How to Install unattended-upgrades package in Debian/Ubuntu?
|
||||
|
||||
By default `unattended-upgrades` package should be installed on your system. But in case if it’s not installed use the following command to install it.
|
||||
|
||||
Use **[APT-GET Command][1]** or **[APT Command][2]** to install unattended-upgrades package.
|
||||
|
||||
```
|
||||
$ sudo apt-get install unattended-upgrades
|
||||
or
|
||||
$ sudo apt install unattended-upgrades
|
||||
```
|
||||
|
||||
### Method-1: How to Check if any Security Updates are available in Debian/Ubuntu?
|
||||
|
||||
It’s always a good practice to check list of available security updates before performing the patch installation. It will give you the list of packages that are going to be updated in your system.
|
||||
|
||||
**What’s dry run?** Most of the Linux commands have a dry run option, which stimulate the actual output but nothing will be downloaded or installed.
|
||||
|
||||
To do so, you need to add `--dry-run` option with unattended-upgrades command.
|
||||
|
||||
```
|
||||
$ sudo unattended-upgrade --dry-run -d
|
||||

If the above command output says **“No packages found that can be upgraded unattended and no pending auto-removals”** in the Terminal, this implies your System is up-to-date.
|
||||
|
||||
### How to Install available Security Updates in Debian/Ubuntu?
|
||||
|
||||
If your got any package updates in the above command output. Then run the following command to install them.
|
||||
|
||||
```
|
||||
$ sudo unattended-upgrade -d
|
||||
```
|
||||
|
||||
Alternatively this can be done from apt-get command. It’s bit tricky. However, i would suggest users to go with first option.
|
||||
|
||||
### Method-2: How to Check if any Security Updates are available in Debian/Ubuntu Using apt-get Command?
|
||||
|
||||
Run the following command to check list of available security updates in your Debian/Ubuntu system
|
||||
|
||||
```
|
||||
$ sudo apt-get -s dist-upgrade | grep "^Inst" | grep -i securi
