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.

After trying secure boot out, my Ethernet connections don't work anymore? (feddit.de)

Hey. Short story: I activated Secure boot on my MSI Mainboard and bootet in my new Debian. I realized that I had no wired internet connection and rebooted the system to deactivate secure boot again. Problem is that now my whole Ethernet is borked? I don't get a connection in Debian or my older OpenSuse partition and the Debian install USB stick says that the connection doesn't work. Of course I deinstallieren Windows and now this happens. Tried already a different cable . Any idea what I could do?

Interesting typo. Puts your default language to german. :)

But to answer your question: There are two not uncommon things I‘d like you to rule out.

defective ethernet port, just now gave up
some kind of „wrong port“ situation where one swears they used this one but it actually was another port they used earlier (happened to me once).

If both are ruled out, check if the network adapter is showing „up“ or working condition even without the cable.

I‘ve had a situation where my network adapter was „down“ because I installed it later and the installation (ubuntu in my case) didn’t know it and when I rebooted it defaultet to eth2 instead of eth0 or something.

Good luck.
