Hi all, I follow this lesson
https://learn.kodekloud.com/user/courses/devops-pre-requisite-course/module/9c8f26c1-90d7-488f-a675-1b77e777c173/lesson/b59f934c-4bca-4b71-960f-65dbeac32a49
to install VirtualBox and centos into my Windows laptop. After normal starting , I try to run command “yum update”, it shows error during downloading metadata for respository ‘baseos’.
cat /etc/resolv.conf
#Gernerated by NetworkManager
search home
nameserver 212.230.135.2
nameserver 212.230.135.1
I tried to ping either “212.230.135.2” or “212.230.135.1”, it shows
ping: connect: Network is unreachable
I tried to ping 8.8.8.8, it also shows:
ping: connect: Network is unreachable
Hi @wuyeelok
Looks like the networking on your VM is not configured properly.
Did you update the Networking settings by changing it to Bridged Adapter?
Hi I have already set it to Bridged Adapter as stated in the tutorial.
But still not network.
For you interest: my laptop was connecting to WIFI
Try pinging 8.8.8.8
This still looks like a network configuration issue, you can’t connect to a DNS server to check the hostname mirrors.centos.org
I tried to ping 8.8.8.8, it also shows:
ping: connect: Network is unreachable
That’s the issue. You need to fix the DNS resolution.
Try adding nameserver 8.8.8.8 in the /etc/resolv.conf
To get it working on my Windows 11 laptop. I had to complete the steps below
nmcli connection up enp0s3
ip a
nmcli connection up enp0s3
works but it seems I need to run this command every time I restart my VM
(after running the command)I need to edit the following file in path
/etc/NetworkManager/system-connections
enp0s3.nmconnection
and set autoconnect=true
After that I can still connect to the internet after restarting the VM
