Then something is really wrong.
Output of the id command is this?:

uid=0(root) gid=0(root) groups=0(root)

Whats the output of ls -la /etc/apt? Should look like this:

...
-rw-r--r--   1 root root  475 Jan  5 07:29 sources.list
...

you need to add some tools which one you want to use, like vi or nano

the correct comand:

vi /etc/apt/sources.list

*face palm* Didn't see that...
But without vi experience I would recommend nano. Its more noob friendly. So nano /etc/apt/sources.list and then save with CTRL+X, Y.

Sounds like you setup a wrong DNS server. Put your routers IP or a public DNS server like 8.8.8.8 in /etc/resolv.conf.

Like before, you need to use a textfile editor like nano to edit a file.

Hi see below, and still not resolved, i cant ping 8.8.8.8 ; 8.8.4.4 or even 1.1.1.1
i dont know why

 

[Dunuin]

If you can't ping 8.8.8.8 then you probably setup a wrong gateway. Check that the gateway IP in /etc/network/interfaces is really your routers IP (so I would guess 192.168.1.1).

There is your problem. You should google what a gateway is and what it does. Change it to your routers IP (for example 192.168.1.1) and then restart your networking using systemctl restart networking.

Unfortunately the command doesn't work on the newer Ubuntu versions. Can you help me solve the problem in Ubutu version 24?

Based on your comment, you will be better off starting a new thread. This one was troubleshooting host networking (PVE is Debian). You are asking about (probably a VM) where you run Ubuntu with unknown context. If you need to check network setup on Ubuntu server, there would a yaml file in /etc/netplan directory. Maybe you are just looking for: ip a

Start a new thread with Ubuntu in the subject.

I had the same problem which is described in this thread,
but I can't solve it because the command /etc/network/interfaces don't work in versions above 18.04 in Ubuntu.

Same issue, different platform does not lead to the same solution. You need to make a new thread

I usually do not care much for organisation, but if I reply multiple threads over time I get completely confused if subject in the notifications does not correspond to the topic at hand. But there's always one more thing ... I believe for new accounts there's often higher chance of getting spam filtered as opposed to adding to existing thread.
