wget Removed from Ubuntu Server 25.10 Default Install And No Its Not Because of Rust

Wget Removed from Ubuntu Server 25.10 Default Install: What You Need to Know

The upcoming release of Ubuntu Server 25.10 marks a subtle yet significant shift for system administrators and developers alike: wget, the ubiquitous command-line utility for retrieving files over HTTP, HTTPS, and FTP, will no longer be included in the default installation. In its place, wcurl, a wrapper around the popular curl command, steps in to handle basic file retrieval tasks. This decision, while seemingly minor, raises important questions about the evolving landscape of system administration tools and the direction Ubuntu Server is taking. This is not due to the increasing use of the Rust programming language in system utilities, and the reasons are more nuanced.

Understanding the Wget Removal: A Detailed Look

The removal of wget isn’t a knee-jerk reaction; instead, it represents a calculated move by Canonical, the company behind Ubuntu. The primary driver is not simply to reduce the initial image size, although that is a welcome side effect. It is more about a push for modernity and focusing on the core functionalities most users need right out of the box. Ubuntu Server aims to provide a lean, efficient foundation, letting users build upon it based on their specific requirements.

The Role of Core Functionality:

Ubuntu Server’s philosophy has always leaned towards minimalism in the default installation. Only the most essential tools for system management and initial configuration are included. This approach minimizes the attack surface, reduces resource consumption, and simplifies the overall maintenance burden. Wget, while powerful and versatile, offers a range of functionalities that are often not required for basic server operation.

Redundancy and Overlap with Curl:

Curl has evolved into a highly capable tool, offering a superset of wget’s functionalities. While wget specializes primarily in file retrieval, curl supports a broader range of protocols and functionalities, including:

Detailed HTTP header control: Curl allows for granular manipulation of HTTP request headers, enabling fine-tuning of client behavior.
Advanced authentication mechanisms: Curl supports various authentication schemes, including Kerberos, NTLM, and OAuth.
Proxy support: Curl boasts extensive proxy configuration options, enabling secure communication through intermediaries.
SSL/TLS certificate management: Curl provides robust tools for verifying and managing SSL/TLS certificates, ensuring secure connections.

By leveraging wcurl, Ubuntu Server effectively provides core download capabilities without duplicating functionality already present in curl, which is included by default. wcurl essentially acts as a simplified interface to curl for common wget-like operations.

Wcurl: A Simplified Interface to Curl

wcurl is not a completely new utility; rather, it is a wrapper script that translates simple wget-style commands into their curl equivalents. This approach offers several advantages:

Maintaining Familiarity:

System administrators accustomed to wget’s syntax will find wcurl relatively easy to use. The familiar command-line options and behavior are preserved, minimizing the learning curve. For example, a simple download using wget:

wget https://example.com/file.txt

Can be achieved with wcurl as:

wcurl https://example.com/file.txt

The script takes care of translating these commands into the appropriate curl invocations.

Leveraging Curl’s Power:

Under the hood, wcurl relies on the robust capabilities of curl. This means that users benefit from curl’s extensive protocol support, security features, and advanced configuration options, even when using the simplified wcurl interface.

Reduced Footprint:

By eliminating the need for a separate wget installation, Ubuntu Server reduces the overall system footprint. This is particularly beneficial in resource-constrained environments, such as virtual machines and embedded systems.

What This Means for System Administrators

The removal of wget from the default installation has several implications for system administrators:

Dependency Management:

If your applications or scripts rely explicitly on wget, you will need to install it manually:

sudo apt update
sudo apt install wget

Consider updating your scripts to use wcurl or, if more advanced features are needed, calling curl directly.

Learning Curl:

While wcurl provides a convenient bridge for basic file retrieval, administrators should take the time to familiarize themselves with curl’s capabilities. This will enable them to leverage its full potential for more complex tasks.

Script Compatibility:

Review your existing scripts that use wget and determine if wcurl can adequately replace it. If not, either install wget or modify the scripts to use curl directly. In most cases, a simple search and replace of wget with wcurl will suffice for basic download operations.

Embrace the Change:

This change encourages the use of a more versatile and powerful tool, curl. This can ultimately lead to more efficient and secure system administration practices.

Wget vs. Curl: A Detailed Comparison

While wcurl aims to bridge the gap, it’s essential to understand the differences between wget and curl:

Scope and Functionality:

Wget: Primarily focused on file retrieval over HTTP, HTTPS, and FTP.
Curl: A more general-purpose tool for transferring data with a wide range of protocol support, including HTTP, HTTPS, FTP, SFTP, SCP, IMAP, POP3, SMTP, and more.

Command-Line Options:

Wget: Offers a simpler set of command-line options, optimized for basic file retrieval tasks.
Curl: Provides a more extensive and complex set of options, allowing for fine-grained control over data transfers.

Complexity:

Wget: Generally easier to learn and use for basic file downloads.
Curl: Requires a steeper learning curve due to its greater complexity and breadth of features.

Use Cases:

Wget: Ideal for simple, straightforward file downloads, such as retrieving software packages or downloading web pages.
Curl: Suitable for more complex tasks, such as interacting with APIs, submitting forms, and performing authenticated data transfers.

Why Not Rust? Dispelling the Misconceptions

The tech world is increasingly embracing Rust for system-level programming, thanks to its memory safety and performance benefits. It’s tempting to assume that the removal of wget is tied to a broader shift towards Rust-based alternatives. However, this is not the case. The decision is primarily driven by the desire to streamline the default installation and consolidate functionalities around curl.

Rust’s Growing Influence:

While Rust is not directly related to this change, its growing influence in the Linux ecosystem is undeniable. Many new system utilities and core components are being written in Rust, offering improved security and performance compared to traditional C/C++ implementations.

Wget Replacements?

Some potential wget replacements written in Rust exist, but are not mature enough to replace it at the operating system level.

Focus on Practicality:

The decision to remove wget is based on practical considerations, not on a philosophical shift towards a particular programming language. Canonical aims to provide a stable and efficient base system, and the removal of wget aligns with this goal.

Installing Wget on Ubuntu Server 25.10

If you require wget for specific tasks, installing it is straightforward:

Update the package list:
```
sudo apt update
```
Install wget:
```
sudo apt install wget
```
Verify the installation:
```
wget --version
```

After installation, you can use wget as you normally would.

Alternatives to Wget and Curl

While wget and curl are the most popular command-line tools for file retrieval, other alternatives exist:

Aria2:

Aria2 is a lightweight, multi-protocol download utility with support for HTTP/HTTPS, FTP, SFTP, Metalink, and BitTorrent. It offers features such as multi-segment downloads, metalink verification, and remote control via JSON-RPC.

Axel:

Axel is a command-line download accelerator that splits files into multiple segments and downloads them concurrently, increasing download speed.

Powershell’s Invoke-WebRequest (for Windows Environments):

While not a Linux tool, if you’re dealing with cross-platform scripting, PowerShell’s Invoke-WebRequest cmdlet provides similar functionality for downloading files.
