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.

Fedora 42 / KDE - What is the difference between "dnf upgrade" and Discover "system upgrade" (sh.itjust.works)

I usually update through dnf but sometimes Discover says there is a "system upgrade" with however many packages that are pending upgrade, but no details provided. It requires a restart after completing.

What is the difference between the two?

Using dnf is betrer than using Discover. Mostly because sudo dnf history undo last exists, which undoes the latest "transaction".

(Each transaction is an action of removing, reinstalling, updating and installing (a) package(s).)
