my problem is that i get error messages when running "sudo pacman -S plasma sddm" . I also get somewhat the same error messages when running "sudo pacman -Syyu" . (( The last line of error is as follows " error: failed to synchronise all databases (failed to retrieve some files)" if further information is needed just ask 😄 Thanks for ur time

does it say some mirrors were unable to be reached

vestal cedar Aug 1, 2025, 2:52 PM

#

Not that i can see. Although it does mention «mirror»

ping 8.8.8.8 and ping archlinux.org pretty please

#

If both fail your connectivity is busted somehow, if the 1st works and the 2nd fails then it's DNS

vestal cedar Aug 1, 2025, 3:01 PM

#

"ping 8.8.8.8" worked fine giving me back 64 bytes. running "ping archlinux.org" gave me "ping: archlinux.org: Temporary failure in name reselution" . is this the DNS u were talking about? PS: i wrote "ping archlinux.org" correctly

void halo Aug 1, 2025, 3:02 PM

#

i think systemd-resolve is what is used for DNS management on arch

Has your network ever worked on this installation?

Did you enable Network Management in the iwd config?

#

If you haven't, you can do this by editing /etc/iwd/main.conf and adding

[General]
EnableNetworkConfiguration=true

vestal cedar Aug 1, 2025, 3:18 PM

#

i have added it already, with "sudo nano /etc/iwd/main.conf". ( trying without sudo gave me a red message that "is unwritable in it" ) . so i have already added it. PS : I tried plugging ethernet cable and got connection to "archlinux.org" after 1-2 minutes. if that information helps.

#

it seems like the problem to connecting to archlinux.org is only with wireless connectivity.

Are you update to run pacman -Syu with ethernet?

vestal cedar Aug 1, 2025, 3:22 PM

#

running "pacman -Syu" gave me "error: you cannot perform this operation unless you are root". I tried this with ethernet cable and got the same error message.

void halo Aug 1, 2025, 3:22 PM

#

do

#

sudo pacman -Syu

#

it needs to be ran as root

#

sudo elevates you to root for that command

viral shard Aug 1, 2025, 3:24 PM

#

Just so you know, any command that edits system files and things like that need to be run as the root user, so you'll need to run them with sudo or use some other method of being root

vestal cedar Aug 1, 2025, 3:26 PM

#

i ran "sudo pacman -Syu" with ethernet cable and got "there is nothing to do" right after ": : Starting full system upgrade"

#

running "sudo pacman -Syu" without cable gave me the same error messages as always

You could try using a different network software like Network Manager and see if that makes any difference

#

So with ethernet plugged in, install Network Manager by running sudo pacman -S networkmanager

void halo Aug 1, 2025, 3:30 PM

#

why are you using iwctl directly over just using networkmaanger with iwd's backend?

viral shard Aug 1, 2025, 3:33 PM

#

viral shard So with ethernet plugged in, install Network Manager by running `sudo pacman -S ...

Once you've done this, disable and stop iwd with systemctl disable --now iwd (--now just means to also stop it), and enable and start Network Manager with systemctl enable --now NetworkManager

vestal cedar Aug 1, 2025, 3:36 PM

#

i have disabled and enabled the suggested software i will now look at a tut on how NetworkManager works and try to connect my self to wifi. i might brb.

vestal cedar Aug 1, 2025, 3:37 PM

i dont know tbh i just stumbled upon it first i think, and i suppose i thought it was easy t use.

#

Hoyl Shit it worked

void halo Aug 1, 2025, 3:47 PM

#

glad to hear it

vestal cedar Aug 1, 2025, 3:48 PM

#

i am now downloading plasma and sddm. using NetworkManager really helped. Thank you people so much. I now have wifi thanks to you. getting wifi connectivity has really been a big obstacle with setting up linux. Thank you again 😄 😄 😄 😄 😄 😄

void halo Aug 1, 2025, 3:49 PM

#

just in future now that you're on network manager if you do want the iwd backend later (it is more reliable) you can set it in its conf file

.n solved

[SOLVED] Cant install packages in already installed arch.

#

for future reference a dhcp client is needed, and a resolver, to use iwd

https://wiki.archlinux.org/title/Iwd#Enable_built-in_network_configuration
https://wiki.archlinux.org/title/Systemd-resolved

#

iwd needs to be restarted after the configuration file is written

#

for systemd-resolved enable and start the service:

systemctl enable --now systemd-resolved
