I cannot update the Microsoft Edge Beta browser. Under "Microsoft Edge -> Help and Feedback -> About Microsoft Edge" only the version number "102.0.1245.14 (Official build) beta (64-bit)" is displayed. And when I enter
sudo apt-get upgrade microsoft-edge-beta
via the terminal, this comes up:
microsoft-edge-beta is already the newest version (102.0.1245.14-1)
The difference is that to update, you'll need to download a new .deb file. If you want to use apt or apt-get to update edge, follow their instructions for the command line install at https://www.microsoftedgeinsider.com/en-us/download :
WARNING: I'm not sure if the code below will work without uninstalling edge first, so beware.
