A quick (not complete) solution that worked for me on Ubuntu 26.04 (GNOME 50.1):
To install and enable the Open Bar extension on GNOME 50, download the extension from the GNOME Extensions Store. Because it may not natively declare support for GNOME 50, you will need to manually edit its metadata.json file to add "50" to the supported shell versions, then restart your session.
Manual Installation & Setup
- Install the Extension: Go to the Open Bar GNOME Extensions Page and toggle the install switch to "ON", or use the Extension Manager app.
- Open the Extension Directory: Open your terminal and navigate to the local extensions folder:
cd ~/.local/share/gnome-shell/extensions/openbar@neuromorph
- Edit
metadata.json: Open the configuration file with a text editor (e.g., nano metadata.json) and locate the "shell-version" array. Add "50" to the list so it looks like this:
"shell-version": ["45", "46", "47", "48", "49", "50"]
- Restart GNOME Shell: Save the file, close your editor, and restart your session by pressing
Alt + F2, typing r, and hitting Enter (Note: on Wayland, you may need to log out and log back in).
That's it.
