ping google.com gives Temporary failure in name resolution

[MrDragoon]

So I freshly installed Arch Linux, as dual boot using archinstall script and chose the network manager too in one of the options

 

now I’m unable to git clone, ping, pacman -Syy

basically any internet related cmds. I’m currently in a minimal profile, no gui only cli.

 

i tried with systemctl enable NetworkManager it didn’t throw any error but it didn’t even work for me.

 

not sure what the problem is, i tried googling ended up with 2 solutions

1. stackoverflow: that user must have dhcpd and network manager both installed and have to uninstall one, but i dont know how to nor when i tried to do 

systemctl start dhcpcd it gave an error as failed to start and unit … service not found 

2. linustechtips: to enable dhcpcd which i mentioned above 

 

surprisingly it both worked for those users, but not for me

[MrDragoon]

So the website isn’t stack overflow but stack exchange 

https://unix.stackexchange.com/questions/682785/fresh-arch-install-lots-of-could-not-resolve-host-errors

 

here’s an image for ```cat /etc/resolv.conf``` and ```pacman -Syy``` in sudo mode

Can you show us ifconfig?

[MrDragoon]

ok so for some reason when I type ifconfig it gives command not found

Sorry, apparently that's outdated knowledge on my part. (I don't use Arch, and it apparently deprecated net-tools ages ago.)

 

Try this instead:

 

ip addr

If your aiming for a minimal system with a wired connection you can look at systemd-networkd, which is already part of your system.

If your aiming for a minimal system with wireless, then you can use iwd.
If you plan to have a Desktop Environment or need a GUI then NetworkManager is usually preferred.

 

Before anyone can help you need to decide which one you actually want to use.

because it's not part of the base system, its in net-tools and you don't need it.

So I installed minimal as I wanted to go with Hyperland later and was planning to install someone’s dot files from gitlab.

But you need to figure out what you actually want for networking as they are all configured differently.

What would you suggest? I’m unaware of these technical details as of now. My usage will be programming, for now web development later on machine learning too. 

[Nayr438]

For a simple starter to get networking up over a wired connection
systemctl disable --now NetworkManager

 

/etc/systemd/network/20-wired.network

[Match]
Name=en*

[Network]
DHCP=yes

 

systemctl enable --now systemd-networkd

systemctl enable --now systemd-resolved

ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

I edited the above post, so please re-read it if you have already.

I’m actually using WiFi and not an Ethernet connection, hope that’s not an issue here.

I gave it a shot, don’t know how much is correct but at the end got some errors

 

[Nayr438]

So then you don't have iwd. Since you have NetworkManager already.
systemctl disable --now systemd-networkd
systemctl enable --now NetworkManager

then follow this, RedHat: Managing wifi connections with nmcli

Thank you so much, this totally worked

[Nayr438]

Glad it's working.
I would however try to re-symlink /etc/resolve.conf. I'm not sure why it failed in in your screenshot.

which is just

 ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Could you possibly also help me reset it to the new? I somehow already made this go bad. I tried to install dotfiles and now I can’t use it when I write qtile, I didn’t try hyperland yet though

heres an image too

and somehow it changed the normal appearance of the terminal which is bothering me.
