[SOLVED] I can’t connect to internet after installing Arch Linux!

ABOhiccups · 2023-07-17 08:19:42

After I installed Arch Linux and GRUB to my SSD.

I reboot the computer. I login as root.

I enter a command for wired Ethernet.
dhcpcd

I get “Failed to revert interface configuration:” errors.

I enter “wifi-menu” and connect to my router.

I enter “ping -c 5 google.com” to make sure I have internet. The command line failed and I’m not connected to internet.

Has anyone have this issue too while installing Arch Linux?

Is there a way to fix it?

Edit: Turns out there was a bug or something where Arch Linux won’t grab a DNS Server from our main network. We just have to manually add DNS Server. Here’s a fix.

Enter “nano /etc/resolv.conf” and insert

nameserver 1.1.1.1
nameserver 1.0.0.1

sounds like you may already be running a network service that is started before logging in.

What is the output of ip link, ip -addr, ip route and ip -6 route just after logging in ?

I tried to run pacman -Sy command and all mirrors url has errors. That tells me I’m not connected to the internet.

Lone_Wolf · 2023-07-17 11:51:48

pacman -Sy command

Don't run that , run pacman -Syu instead.

The failure of the pacman command indicates DNS resolution on your system doesn't work, but that's not the same as having no network connection .

In order to connecct with a website/url many things have to work together.
The output of the commands I asked should give enough info to verify a big part of those things and allow narrowing down possible causes..

I run pacman -Syu. All mirrors has errors and won’t update.

There is something wrong with Arch Linux that won’t connect online after installing to SSD. I can connect online in ISO Boot just fine.

seth · 2023-07-17 21:30:52

There's nothing wrong with archlinux.
What network daemon did you install and configure and how did you configure it?
What is the output of

ip a; ip r; ping -c 1 _gateway; ping -c1 google.com

Don't narrate that, link a screenshot in doubt.

Here’s a list of Network Drivers I’ve installed before reboot to SSD.

dhcpcd
dialog
netctl
ppp
wireguard-tools
wireless_tools
wpa_supplicant

seth · 2023-07-17 21:42:51

This are not "network drivers", "dialog" doesn't even relate to networking and you've not explained how you configured those.
Add

netctl list

to the list of commands you'll post the output for.

I enter netctl list. It’s not listing profiles or drivers.

*link*, the board has a 250x250px max rule. Replace the image with a thumbnail or link.
Also it's not most of the commands that I asked for but "no interfaces have a carrier" is an *OBVIOUS* roadblock.
You'll have to plug a cable into the ehternet port…

The Ethernet cable was plugged in to my laptop. I can connect to internet in ISO boot. But I can't connect to internet in SSD Boot during post-installation.

seth · 2023-07-17 22:55:16

The Ethernet cable was plugged in to my laptop.

dhcp thinks differently.
Don't repeat some fairy tales over and over again, post the output of the commands I asked for.
And obviously check the cable seating. If it's loose (sometimes the latch protection collides with the case of your PC and prevents it from fixing) you'll get erratic behavior out of that.

While at it, also

lspci -k

I think it's not my PC or my own network. I use both Ethernet and Wi-Fi on ISO Boot. I can connect to the internet just fine and I can download and install packages that I need before reboot to SSD Boot.

In SSD Boot. I use both Ethernet and Wi-Fi. I can't connect to internet. For Ethernet, I need to enter dhcpcd and it has errors. I enter wifi-menu and connect to my router through Wi-Fi and enter pacman -Sy (and pacman -Syu) and all mirrors has errors. I enter ping -c 5 google.com and it tells me I'm not connected to internet.

I don't know if there's a extra step I missed.

Here's how I install Arch Linux.

In ISO Boot. First thing I need to connect to internet. For Ethernet, I'm good to go! But for Wi-Fi. I have to enter iwctl command. After I enter ping -c 5 google.com. I am connected to internet.

Then I use luks commands to create Encryption Partition and create 2 lvm2 group partitions in an Encryption Partition. 1 for Root and other for Home. I create Boot partition and I have EFI partition (512 MB) from Windows 10/11. I format both Boot partition and Root and Home groups as EXT4. Then I mount both partition and groups to /mnt directories.

Then I install Arch Linux to Root Group by using pacstrap command. Then I enter chroot-arch to go into /mnt.

Then I install Kernels, Networks, FS Formats, and other important packages I need with pacman command. I setup lvm2 encryption, locale, time zone, and Root Password. I mount EFI partition to /boot/efi. Then I install and setup GRUB. Exit /mnt. Run genfstab command. Umount all partitions and reboot to SSD boot.

I login to Root. I enter dhcpcd (for Ethernet) or wifi-menu (for Wi-Fi). I enter ping -c 5 google.com and pacman -Syu. And here I am. No internet for me. I can connect to internet on Windows 10/11, my Smartphone, my Smart TVs, and my Game Consoles. It's just post-installed Arch Linux I can't connect to internet right now.

If anyone knows there is a bug or extra steps I did not do. Please, with me know.

How do I scroll up the terminal? So I can take a picture you asked for 1 by 1.

I can only take the picture at the end of outputs.

Scroll up/down on text consoles was removed from linux sometime ago.

An alternative is to redirect the output of the commands to a text-file , example :

ip -a > output-of-ip-a.txt

copy those textfiles to an usb stick and post their contents using any system with internet access & usb ports.

You've a lease and can ping the gateway, this is exclusively a dns issue.

resolvectl status
cat /etc/resolv.conf

I enter that command and I get this.

I was using Cloudflare DNS with 1.1.1.2 to block malware sites. Did Cloudflare thinks hdcpcd and wifi-menu is a malware?

Is there an option to add DNS to local Arch Linux Network? Or I have to change DNS on Router?

seth · 2023-07-18 20:35:17

You haven't configured any DNS server
You can temporarily append "nameserver 8.8.8.8" to that file (or 1.1.1.1 or 1.1.1.2) and then post a complete system journal so we can finally see wtf you're doing over there

sudo journalctl -b | curl -F 'f:1=<-' ix.io

ABOhiccups · 2023-07-23 05:30:03

It's not DNS server. dhcpcd and wifi-menu has issues where you can't connect to internet during post-installation. The best workaround is to boot into Arch Linux ISO. Mount Root Partition and run "arch-chroot /mnt" and then download networkmanager and enable networkmanager at startup. Then unmount everything and reboot.

I should be able connect to the internet and finish setting up Arch Linux.

Arch Linux
