when I type
sudo pacman-mirrors -f && sudo pacman -Syyu
I get the following error

I’ve also tried commands
sudo pacman-mirrors -f5 && sudo pacman -Syyu
sudo pacman-mirrors --continent && sudo pacman -Syyu
but nothing helps.

Please help in solving the problem. Thank you=)

Did you modify your DNS? It rather seems like a networking issue.

Can you open one of the mirrors in your browser? E.g. Index of /manjaro/stable

I tried with automatic DNS and DNS from cloudflare, but the error still appears.

4

until you know that you do indeed have a working connection
there is no point in running the two consecutive commands:

do them one at a time …
sudo pacman-mirrors -f or another variant
and only if and when that succeeded:
sudo pacman -Syyu

No, the links do not open in the browser. Some kind of connection error. But I can’t figure out which one. Internet connection is there.

sudo systemctl status systemd-networkd

systemd-networkd.service - Network Configuration
Loaded: loaded (/usr/lib/systemd/system/systemd-networkd.service; disabled>
Active: active (running) since Thu 2023-01-26 07:26:57 EST; 1min 45s ago

sudo systemctl status NetworkManager.service

NetworkManager.service - Network Manager
Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled; p>

The service is running but that doesn’t magically give you a working connection.

Reboot your router or cable modem if you can - power cycle it.

Then disconnect from and re-connect to it.

And re-check the configuration in the NetworkManager GUI which you likely have altered.

…

you know that you have to change the method from “automatic” to “automatic, addresses only” when you want to use a custom DNS server?

Can you ping the IP?
(1.1.1.1 for cloudflare or 8.8.4.4 for one of googles DNS servers)

7

Evidently, you don’t have a working internet connection.

8

curl ifconfig.me doesn’t work. No connection to the server.
I changed DNS differently, with and without it. Automatically and without.

Rebooting the router didn’t help either.

Internet works fine on other devices.
it is not clear what happened. always like this with manjaro =)

9

Ways to start assessing the problem (that I know of - may not be the most efficient):

check:
ifconfig

or
ip addr

have a log running in a terminal while you disconnect and connect

journalctl -f

or

sudo dmesg -w

so you can see what is and is not happening

10

Pls, show us the output of DNS server list your Manjaro OS copy uses:

cat /etc/resolv.conf
11 
Generated by NetworkManager
nameserver 192.168.1.1
12

:man_shrugging: What was the result of my suggestions above?
Was it useful? Did you try?

and the one prior to that:
Can you ping the external nameserver?
example:
ping -c 3 1.1.1.1

13

I tried, but didn’t get any information that would be useful to me. Maybe I’m misinterpreting it.

About ping -c 3 1.1.1.1 I will try it later. Thanks )

14

But to us. Please provide the asked information.

Also it doesn’t hurt to include a inxi -Fazy report.

15

Are you running both systemd-networkd and NetworkManager?

From the Arch Wiki on network managers:

Note: There are many solutions to choose from, but remember that all of them are mutually exclusive; you should not run two daemons simultaneously.

16

:+1: oops - I only saw that it was disabled - but not that it was also running

17

With this kind of troubles, it’s good to try this universal fix:

sudo rm -r /etc/pacman.d/gnupg
sudo pacman -Sy gnupg archlinux-keyring manjaro-keyring
sudo pacman-key --init
sudo pacman-key --populate archlinux manjaro
sudo pacman-key --refresh-keys
sudo pacman -Sc
sudo pacman -Syu

Basically, what it does: deletes the pacman database (that may be corrupt), ensures some vital packages are up to date, rebuilds, refreshes the keys, populates database.

Anyway, even if this won’t help, it won’t hurt trying. However, this set of commands usually fixes various problems with updates and keys., sometimes even with manjaro-mirrors.

It seems unlikely that it will or even could - because there is no working internet connection.

no internet connectivity

That is very likely the IP of your own machine.

Please report back the results of the example commands above.

ip addr
or
ifconfig

… and the rest as well

You have two services running - you only need one: NetworkManager
