MS Edge - Sidebar and copilot not working on Linux Ubuntu v24 LTS

It seems especially unfortunate that the Linux builds of Edge omit the sidebar code path entirely, with no feature flags, policies, or workarounds available. Many developers and IT professionals choose Linux as their primary environment. By withholding a core UI feature from Linux users, Edge creates an unnecessary second‑class experience for a large segment of your audience.

Copying HubApps from a Windows install worked, it's a shame though that this hasn't been fixed yet.

I wanted to say this is the first time I've found an actual fix for a problem via this site. Thanks a million Zazo58 ! Copied HubApps to by profile folder from another device, and immediately the side bar is working.

Brilliant! Copied the hubapps file from my windows pc to my Deepin install. Thanks a lot, works perfectly. 😎

It's now 15th of February and it still breaks after updating Edge. Just copied the HubApps file to my profile directories again. Copilot is so important to Microsoft but less so on platforms other than Windows. 

the file that is missing is called HubApps, and it can be copied from any edge install, on windows it would be here:

AppData/Local/Microsoft/Edge/User Data/Default/HubApps

this file needs to be copied to:

flatpak version:

.var/app/com.microsoft.Edge/config/microsoft-edge/Default/

regular install:
.config/microsoft-edge/Default/

and restart edge, then copilot will work.

also might have to copy into other profiles if you have some

all of this info is above but unclear, ive also added a link to a copy of the file if you do not have a working install

Weirdly, I have the issue on arch linux, everything updated, it seems like the problem is so generalized, it would be good to fix it centrally from MS side.
