From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there a way to add "Run as Sudo" to context menu like with Windows? (lemy.lol)

I found a (lengthy) guide to doing this but it is for gksu which is gone. I have to imagine there's an easy way. I am running Ubuntu. There is no specific use case, it is just a feature I miss from windows.

EDIT: I always expect a degree of hostility and talking-down from the desktop Linux community, but the number of people in this thread telling me I am using my own computer that I bought with my own money in a way they don't prefer while ignoring my question is just absurd and frankly should be deeply embarrassing for all of us. I have strongly defended the desktop Linux community for decades, but this experience has left a sour taste in my mouth.

Thank you to the few of you who tried to assist without judgement or assumptions.

gksu and kdesu are unsupported for >10 years iirc, they were not more secure than sudo and that's one of the reasons they were abandoned. I've never heard about sux. Polkit is a bit another thing that indeed replaced them, however it does not and can not separate GUI and non-GUI processes. The process itself has to fork, drop privileges and draw a GUI after that. There's no difference between running it via sudo or pkexec, however polkit provide additional protections to prevent running unsafe apps with elevated privileges.

PAM and GVFS are not "privilege elevation frameworks" whatever you mean by this.

I know.

they were not more secure than sudo

No, they were, barely, but they were, they were wrappers around sudo that provided "a more user-friendly and secure way to run graphical applications with elevated privileges, by handling environment variables and permissions better than using sudo directly."
They've been deprecated in favor of pkexec.
sux is wrapper around su which transfers your X credentials, it sucks, don't use it.

pkexec literally uses Polkit and PAM under the hood.

pkexec runs the program in a "minimal known and safe environment" to avoid potential security issues like code injection through environment variables. pkexec also sets the PKEXEC_UID environment variable to the user ID of the process invoking it, providing more information about the context. pkexec is more secure than using sudo -i for running graphical applications, as it can prevent certain types of privilege escalation attacks. This increased security is largely due to the use of PolicyKit (Polkit) with pkexec. Polkit is a framework that provides a way to define and enforce fine-grained access control policies for privileged operations. With Polkit, the system administrator can define rules that determine which users or processes are allowed to perform specific privileged actions, like running a GUI application as root. This provides more granular control compared to the blanket root access granted by sudo.

PAM and GVFS are not "privilege elevation frameworks" whatever you mean by this.

You're right, PAM is an authentication framework and GVFS is a whole other thing that leverages polkit and authentication agents. My bad.
