Re: Network is unreachable

Post the output of "ip a".
How do you connect to the internet (ethernet or wlan)?

Re: Network is unreachable

So the interface is detected properly you just don't have an IP address yet.

Try...

dhcpcd enp2s0

Did you connect the cable after you'd booted the install media?

Re: Network is unreachable

No. It was connect before i booted the usb.
When i run the command "dhcpcd enp2s0"

sending commands to master dhcpcd process.

Re: Network is unreachable

Is another network service running? Show the output of "systemctl --type=service".

Re: Network is unreachable

disable the service dhcpcd@enp2s0, reboot, start dhcpcd like Slithery said and post the output.

Re: Network is unreachable

Disabling a service on an immutable live disk doesn't do anything.

I didn't realize that it is the live disk. Sorry. ^^

What does journalctl -u dhcpcd@enp2s0 say?

Re: Network is unreachable

Hi,

Is your network support for dhcp? If not, you can set static ip instead of dhcp. Also check for resolv.conf

Re: Network is unreachable

It seems that you have no DHCP-server on your network, so set your IP-aaddress manually and then try to ping your router IP-address, also you have to set dns-server in /etc/resolv.conf, at least to:

nameserver 8.8.8.8

According to #3, he doesn't have an IP address...

Re: Network is unreachable

Haller, FYI DHCP-server (if it present on the local network) is that "tricky thing" that performs network configuration of other devices on the network: giving an IP-address lease, setting a gateway for LAN,  auto-configuring a proxy for browser, notifying about ntp-servers and many many more settings. If your network have no DHCP-server (it can be simply disabled feature on the wi-fi router) so you have to configure all of that things with your own hands. That's what I'm saying
