Microsoft Edge on Linux

First, install VirtualBox: https://www.virtualbox.org/wiki/Linux_Downloads

Then, install the Edge virtual machine for VirtualBox from here: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/

Microsoft Edge for Linux is now available in the Beta and Dev Channels at Microsoft Edge Insider Channels. Packages are available in deb and rpm formats.

Files can also be downloaded from the Microsoft package repositories: DEB, RPM

To examine files before installation:

mkdir /tmp/msedge
dpkg-deb -x microsoft-edge-dev_93.0.957.0-1_amd64.deb /tmp/msedge

After extraction, it's possible to run without installing:

/tmp/msedge/opt/microsoft/msedge-dev/microsoft-edge-dev

Warnings

• If the deb is installed, it will add an apt repository by creating /etc/apt/sources.list.d/microsoft-edge-dev.list. This behavior is inherited from Google Chrome.

• The EULA states the following:

  If you disable data collection through controls available in the Previews, we may continue to collect diagnostic information about the download, the installation and any removal of the Previews and “basic” data as described in the Windows Diagnostics section of the Microsoft Privacy Statement.

Note: This answer previously contained a tutorial about installing Microsoft Edge on WINE. This seems to no longer be possible as a result of changes in the installer, WINE, or both.

Update 2022

Microsoft Edge is available on Flathub and since it is a Chromium based browser, you can use any of the available Chromium based browsers to test (for web development) and the result should be the same.

Update 2018

Microsoft announced that Edge will be released with Blink engine (Chromium) in early 2019. They didn't talk about Linux version yet and at this point only VM and Browserstack works.

Microsoft Edge will now be delivered and updated for all supported versions of Windows and on a more frequent cadence. We also expect this work to enable us to bring Microsoft Edge to other platforms like macOS. Improving the web-platform experience for both end users and developers requires that the web platform and the browser be consistently available to as many devices as possible.

Browserstack

With browserstack there isn't any need for VM or Dual boot. It shows Microsoft Edge on any browser. It will allow to test your local sites.

Till now, developers have been relying on virtual machines or PC’s with Windows 10 to test their products and websites on Microsoft Edge. To provide an easier way to test, Microsoft and BrowserStack are partnering to give developers a cloud based infrastructure to instantly test and ship great experiences on Microsoft Edge.

and about Local Testing Security:

Local Testing enables you to test local folders and internal servers. We use custom-designed Chrome and Firefox extensions, with WSS (secure WebSockets) to connect your machine to the cloud. WebSockets allows extensive interaction between the client browser and the servers and devices. To protect the privacy of transferred data during the testing session, we use WSS exclusively. WSS uses SSL over port 443 for transport and therefore only transmits encrypted data.

When testing an private server, we forge a connection between the server you have specified, and our virtual machines or physical devices. The mechanism is set up to forward requests and responses back and forth, and nothing else. Similarly for local folder testing, the BrowserStack cloud only has access to the folder mentioned during the setup of the connection. Our infrastructure cannot access anything else on your filesystem.

Microsoft Edge for Linux is now in Beta. Read this article for more information: https://www.techradar.com/news/microsoft-edge-for-linux-gets-an-official-beta-release

To install Microsoft Edge from the Beta follow these steps:

(Do note that installing Microsoft Edge, (using the following methods), will add the Microsoft repository so your system will automatically keep Microsoft Edge up to date.)

Method 1

1. Go to https://www.microsoftedgeinsider.com/en-us/download/?platform=linux-deb.

2. Click on Download under the Beta Channel.

   

3. Read the license terms and then press Accept and download.

   

4. A dialogue box might appear in Firefox depending upon the settings. Choose Save File and click OK.

   

5. Open the folder where the .deb file is saved. Right click (not on the file) and choose Open in Terminal.

   

6. Now the terminal will open. Execute the following command:

   sudo apt install ./microsoft-edge-beta_92.0.902.15-1_amd64.deb
   

   Note: The file name may vary. Please use the name of the file which you have downloaded.

Method 2

Screenshot from https://www.microsoftedgeinsider.com/en-us/download/?platform=linux-deb

1. Open Terminal. Execute:

   curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
   

   If curl is not installed, run sudo apt install curl and then run the above command.

2. Run:

   sudo install -o root -g root -m 644 microsoft.gpg /etc/apt/trusted.gpg.d/
   

3. Run:

   sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/edge stable main" > /etc/apt/sources.list.d/microsoft-edge-beta.list'
   

4. Run:

   sudo rm microsoft.gpg
   

5. Run:

   sudo apt update
   

6. Run:

   sudo apt install microsoft-edge-beta
   

Apart from the free virtual machines (that expire after 90 days) Paul posted, you can also use other useful tools like BrowserStack.

Microsoft announced that Edge will abandon it's curent engine to become another Chromium based web-browser. (Like we hadn't enough of those already !) So in the future you won't need to test with Edge as long as you do it with any other Chromium based browser.

In November 2021, Microsoft announced in their blog that the stable version of Microsoft Edge can be installed in Linux devices.

Last October, we made Microsoft Edge available on Linux in preview channels (Dev and Beta channels) and today, the browser is generally available for Linux via the stable channel. This milestone officially rounds out the full complement of major platforms served by Microsoft Edge through stable channel: Windows, Mac, iOS, Android, and now Linux. To use Microsoft Edge on Linux, users can download it from our website or retrieve it using the command line from a Linux package manager.

You can download the .deb file from here and then follow the steps in this answer to install the software.

Note this:

Installing Microsoft Edge will add the Microsoft repository so your system will automatically keep Microsoft Edge up to date.

Microsoft Edge is available to download as a Dev preview channel at https://www.microsoftedgeinsider.com

Everything seems working fine except the sign-in / sync. (Currently, it supports Windows 10 version 1709 and above, and macOS version 10.12 and above.)

No, you can not get Microsoft Edge on Linux/Ubuntu or any other Linux machine. Instead of using Microsoft Edge try using a text editor that comes with your system. A text editor should function almost as well as Microsoft Edge for programming (By the way, I'm a web developer too).
