[SOLVED] new install issues

[agent_kith]

Is Ubuntu Core 24 sufficient for snakeoil os, I just realized I am still having trouble with install on rpi4 2gb version.

I have never tried 2GB model to be honest as I have always uses 4GB or 8GB.  2GB models might not have enough RAM.
 
Things will run, but it will not be ideal.

 

Networking is not getting enabled and ports are not functioning.

Need a lot more details to be honest:

1. What kind of networking do you have at home? Is it a standard router with DHCP server and you are connecting the Pi straight to the router?
   
2. Are you using Wifi? If so, when creating the image, did you setup the wifi properly in the raspberry image writer?
   
3. What ports are not functioning? USB or something else?

Same rpi4 works perfectly fine with any other OS like RPI linux,volumio, gentooplayer etc.

I am using 5g router, everytime I setup wifi credentials during imaging in rpi imager as well as connect a lan cable during bootup.

Cant communicate with ports.ubuntu.com is the message i see during bootup process. When I say ports they are domains.. cant ping google.com.

My router is assigning the rpi4 an ip, I can see that based on the mac address(autoassign not fixed). I am not able to communicate using putty or directly also after login.

I rechecked 2 days ago that SO 1.4.3 works with my CM4 (Pi4) using UBuntu 24.04 Server. No problems with network.

Yeah, my issue is only with ubuntu install and proceeding to next level of updates which requires networking to function on my rpi4.

Looks similar to my issue.

Connect a monitor and keyboard to your Pi2GB. Flash a image of Ubuntu server, and then do the following:

1. Confirm you're seeing a login console. If yes, login to the console (using the name and password you specified during the image)
   
2. Login and confirm you're seeing a shell
   
3. Run this command: ping 1.1.1.1 (Is this ok?)
   
4. Run this command: ping google.com (is this ok?)
   
5. Show me the output of this command: ip a
   
6. Show me the output of this command: route -n
   

Start with these and we work on from there.

Hi, 3 and 4 don't work because there is no internet connectivity due to dns issue?  when  I plug in a different sd card with rpi os everything works perfectly(lan, wifi,touchscreen). I have tried ubuntu on 3 different sd cards/ usb drives. currently trying to install on an old laptop instead.

4 is a DNS issue. In step 3, pinging the IP address of 1.1.1.1 is testing your network connectivity directly. When step 3 fails it means your network is not up.

You need to show me the outputs from step 5 and 6. I need these information to know more about what is wrong.

So if you look at the section that says "eth0" and "wanlo", both are down. This means your Pi is not configured to use the network. 

When you install Ubuntu via rpi-imager, did you setup the Wireless setting? If yes did you use the wrong SSID or password or something?

Try these steps:

1. Reflash a copy of Ubuntu server for Raspberry Pi
   
2. In the settings, do not fill in your wifi details.
   
3. Insert the microsd into the Pi
   
4. Connect a network cable from your router straight to the Pi. Your router should have DHCP server running. This DHCP server will give an IP address to your Pi. Without a IP address your Pi will not be able to connect to the Internet. Double check your router that it is giving out a DHCPv4 address. (It may be possible you are using IPv6 only over at your place).
   
5. Power on the Pi.
   
6. Wait a few minutes and make sure the LED lights on the Pi is lit up. If the LED lights are up, then you will at least rule out physical connectivity problems.
   
7. Log in to your router, and look under your LAN (Local Area Network) settings. You should see a list of clients and your RPi must be in it.
   

Technically you can use wireless connectivity for this, but the WebApp do not support wifi setup yet so I would not suggest you try that now. 

If you followed the above, your network configuration (/etc/netplan/50-cloud-init.yaml) should look like this:

Code:

# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2

So what this configuration is saying is I want to use eth0 (wired Ethernet), and it will get a IP automatically from a DHCP server.

Technically if you modify this file and use the above settings, your Pi will be connected to the Internet (bar some weird hardware failure).
