Linux Operating System DEBIAN 13 _ COPILOT software not working under DEBIAN 13

Copilot , i have a question ? Why can't i run Copilot or why cant't i ask Copilot or why Copilot is not functioning when i am working on my DEBIAN 13 machine ??? For your information Copilot , when i am running Copilot on my DEBIAN 13 machine , i am running Copilot using a MICROSOFT Edge browser for Linux , that is , microsoft-edge-stable_153.0.4234.32-1_amd64.deb, so Copilot , why is this happening ? Copilot , does it mean that COPILOT software is not allowed to operate on a DEBIAN 13 machine , so much so , that COPILOT software is not allowed to operate in any Linux-based machines or any Linux-based DISTRO , DUE TO SECURITY REASONS ? But if that is so , Copilot , you will be surprise that i am running COPILOT and i am asking you this very question on my ZORIN OS 18 machine , which is a Linux-based machine ! Copilot , does it means that COPILOT can work only on a ZORIN OS 18 machine but not on a DEBIAN 13 machine ? Copilot , do have `any idea why COPILOT software is not allowed to operate on a DEBIAN 13 machine ??? THANKS for your answer.


Hi Norizan! 😄

WHOOOOOAAAAA! That is actually a very good question! 🚀

The short answer is:

NO, Copilot is NOT blocked from running on Debian 13.

NO, Copilot is NOT prohibited from running on Linux.

In fact, the strongest proof is right in front of us:

✅ You are currently chatting with me from your Zorin OS 18 machine, which is Linux-based.

And many Linux users access Copilot through:

  • Microsoft Edge for Linux
  • Google Chrome for Linux
  • Firefox for Linux
  • Copilot website (copilot.microsoft.com or copilot.cloud.microsoft.com)

Microsoft itself provides web-based Copilot experiences that run in supported browsers. [learn.microsoft.com], [explore.mi...rosoft.com]

So the problem is very likely something specific to your Debian 13 installation, not Debian itself.

Possible Cause #1: Microsoft Edge profile problem

Since Zorin OS 18 works but Debian 13 doesn't, one possibility is that:

  • Edge on Zorin is logged into your Microsoft account correctly
  • Edge on Debian is not logged in correctly, or the profile is corrupted

Try checking:

Edge
→ Top Right Corner
→ Profile Icon

Make sure you are signed in using the same Microsoft account you use for Copilot.

Possible Cause #2: Old cookies or cache

Sometimes Copilot gets confused by old login information.

Try:

Edge
→ Settings
→ Privacy, Search and Services
→ Clear Browsing Data

Then:

  1. Close Edge completely.
  2. Reopen Edge.
  3. Sign in again.
  4. Visit:

or

Possible Cause #3: Edge Sidebar issue on Linux

There have been reports from Linux users where:

  • Edge itself works
  • Websites work
  • But the Copilot sidebar does not open correctly

Some Linux users have applied fixes specifically for the Edge Linux installation when the Copilot sidebar fails to appear. [dev.to]

Possible Cause #4: Regional Availability

Microsoft's own Copilot website sometimes displays:

"Not available in your region"

when certain services are unavailable from a particular location or configuration. [copilot.mi...rosoft.com]

If Debian is using a VPN, proxy, or different network settings from your Zorin machine, that could affect access.

Possible Cause #5: Edge Version Difference

Microsoft documentation states that some Copilot-related browser features require recent versions of Edge. For example, certain browser-use capabilities require Edge version 152.0.4191.53 or later. [learn.microsoft.com]

You mentioned:

microsoft-edge-stable_153.0.4234.32-1_amd64.deb

That version is actually quite recent, so I do not think the Edge version itself is the problem. [learn.microsoft.com]

Grandpa Norizan's Quick Detective Test 🔍

On your Debian 13 machine, open a Terminal and run:

microsoft-edge-stable --version

Then open Edge and try:

Tell me exactly what happens:

  • Does the page stay blank?
  • Do you get an error message?
  • Does it say "Not available in your region"?
  • Does it ask you to sign in?
  • Does the Copilot icon appear but do nothing?

The exact symptom will tell us where the problem is.

My Honest Opinion

Because:

✅ Copilot works on your Linux-based Zorin OS 18

✅ Edge is installed on Debian 13

✅ Debian 13 and Zorin OS 18 are both Linux distributions

I would say there is about a 95% chance that the issue is related to the Edge profile, login, cookies, network settings, or a Debian-specific Edge configuration, and not because Microsoft is blocking Debian 13 or Linux itself. 🚀

WHOOOOOAAAAA Grandpa Norizan! We shall investigate this mystery like two Linux system administrators hunting down a bug in a data center! 😄💻🐧
