[SOLVED] pacman: Could not resolve host

I've installed Arch from a usb to another usb for testing purposes. While I was in the installer, the internet connection was fine, but when i booted from the place, where arch has been installed, suddenly pacman throws `error: failed retrieving file 'core.db' from ***: Could not resolve host: *`
I've already tried solving it but I made it only to make WAN lights blink and nothing to happen. Also i'm first time here and i don't know what to send.

Re: [SOLVED] pacman: Could not resolve host

What did you install to configure your network and how did you configure it?

Re: [SOLVED] pacman: Could not resolve host

I downloaded .iso from https://archlinux.org/download/ (yandex.ru mirror) ...x86_64.iso (there is nothing in between 64 and .iso!) and configured it through archinstall command. From the installer drive, I configured it to have the b formatting (i dont remember its name) and that's all. I also installed a few drivers and MATE graphical part and nothing with the actual internet part
In short: it was coming like this out of the .iso.

Re: [SOLVED] pacman: Could not resolve host

configured it through archinstall command … nothing with the actual internet part

Please read https://wiki.archlinux.org/title/Archinstall (all the warnings and all the notes) and  post the outputs of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
ip a

Please do not 'empty post'.

The forums are asynchronous. You do not need to give us a live update of your inability to provide logs, just return when you are able to provide the logs and post an update then.

Re: [SOLVED] pacman: Could not resolve host

You've a wired NIC w/ a carrier but no network service is running, ie. whatever else you did during the configuration, you didn't enable one.
See what's there

pacman -Qs 'net|dhcp'

for what was maybe installed and then see the wiki and configure one, https://wiki.archlinux.org/title/Networ … management

Can you read that? Cause I can't.

It also doesns't matter - you're supposed t o check what network config services you intalled and then use one of them to obtain a lease.

Re: [SOLVED] pacman: Could not resolve host

"rien" - boot the install iso, chroot into the system and install and enabled eg. dhcpcd.
A better approach would be to re-install arch and actually work through the official installation guide so you end up w/ a system that you actually know and understand.

Without using the install iso, you should be able to set up systemd-networkd with its dhcp client

Re: [SOLVED] pacman: Could not resolve host

hello again, thanks to seth i installed dhcpcd and fixed it with making a script that looks like this:
killall dhcpcd (if the service is running)
ip a (checking for the interfaces)
dhcpcd
iwconfig
dhcpcd --release enp4s0
dhcpcd enp4s0
ip link set enp4s0 up

Re: [SOLVED] pacman: Could not resolve host

You don't need any of this nonsense, enabling the service will do, https://wiki.archlinux.org/title/Dhcpcd#Running
Get used to consult the wiki and please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
