Enable “Open as Admin” in Nautilus File Browser

Last updated: February 15, 2018

gnome shell

It’s been a long time last time I wrote about how to enable “Open as root” or “Open as Administrator” in Nautilus’ context menu.

A Nautilus extension called Nautilus Admin has been created for a period of time. It’s a simply Python script that adds some administrative actions to the right-click menu:

  • Open as Administrator: opens a folder in a new Nautilus window running with administrator (root) privileges.
  • Edit as Administrator: opens a file in a Gedit window running with administrator (root) privileges.

To install the Nautilus extension:

The extension is available for all current Ubuntu releases: Ubuntu 14.04, Ubuntu 16.04, Ubuntu 17.10, and Ubuntu 18.04.

1. Simply open “Terminal” either via Ctrl+Alt+T or from app launcher. Then run command:

sudo apt-get install nautilus-admin

Input your password (no visual feedback while typing) when it prompts and hit Enter.

2. Then restart Nautilus via command:

nautilus -q

That’s it. Open nautilus file browser again and enjoy with new context menu options!

Last updated: June 6, 2025

Foobar2000, the popular music player for Windows platform, now can be easily installed in Ubuntu via snap, the universal Linux app packaging format.

sudo apt install snapd snapd-xdg-open

2. For Ubuntu 20.04, 22.04, 24.04, and higher, Snap is pre-installed. You may either search & install Foobar2000 from Ubuntu Software or App Center:

Or, run the command below instead to install from terminal window:

snap install foobar2000 --classic

--classic flag is required to be able to access files outside the installation directory.

sudo snap connect foobar2000:hardware-observe core:hardware-observe

sudo snap connect foobar2000:process-control core:process-control

sudo snap connect foobar2000:cups-control core:cups-control

Finally launch the music player from application launcher (may need re-login) and enjoy, though the UI is kinda age-old.

snap remove --purge foobar2000
