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.

How to change password in Ubuntu (lemmy.world)

I've run passwd and sudo su; passwd to change password for root and my account. Password is set correctly when using sudo and su but whenever I get prompted by pkexec it accepts only the old password. I've rebooted my system to make sure it was not an issue.

Edit: Solved Turns out the password were changed for root account but not my user account. I think the reason is that there are no password quality requirements on root accounts, but there are on the default account in ubuntu. Changing the password from root account passwd user worked fine.

Super User Do Super User

If I'm not mistaken "su" stands for "switch user", not " super user".

It's complicated.

Yeah. It's as dumb as cat | grep but people love it.

... despite the added risk during that sudo/su switch.

su needs root's password sudo su just needs your password
