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.

Arch Linux system won't connect to the network/internet (lemmy.ca)

EDIT: forgot to add that the wifi networks all appear fine and connect (network name appears in the settings and connects successfully, just no network access no matter the interface)

EDIT 2: I did not really feel like troubleshooting my computer all day as I had kind of soft-bricked it by downgrading the kernel, and it didn't boot. I felt it was a bit too far gone for me and like I said I didn't want to spend the day fixing it. Anyways I had a separate /home so it was all fine. I installed PopOS as a (not so) temporary solution. Ill probably end up reinstalling Arch or something a bit more up to date soon enough. Thanks everyone for trying to help me!!

Hey there, I'm looking for some help with my Arch system that I updated today.

So a little context here: today, I updated my system with the usual -Syu. However after the update I kept getting pop ups that told me my LAN connection was not working or something ( I use gnome). Wifi was still working.

Now, I since rebooted in hopes the popups would go away (in a sense, they did...), I do not have any access to the internet, I tried everything I can think of (wifi only, wired only, usb tethering with my phone) but nothing works. I still get the wired icon in gnome even though the cable is unplugged.

I am having trouble finding help with the Reddit blackout (convenient timing lol) and it is pretty hard for me to attach logs and such since my computer has no network access at all, I'm relying 100% on my phone...

Any help is appreciated 🙂

I don't seem to have dhcpcd installed on my system (systemctl status dhcpcd says it is not found). Is this a required package that I managed to live without for a few months by pure luck?

You probably use Network Manager so dhcpcd isn't needed.

But doesn’t it still use dhclient in the backend?

[–] Sagar@sopuli.xyz 1 points 1 year ago

Network Manager is too heavy, just mount and pacstrap dhcpcd to the partition, make dhcpcd run on bootup using systemctl or rc-update. NetworkManager is not needed.
