This looks like a network issue (not an apt error).

Have you tested network connectivity on the Ubuntu system?

Is this a new system? Or did networking work properly before?

Hello, I have installed WSL2 and Ubuntu came by default on my Windows 11. I have installed this to run TensorFlow for the ML project. Inter internet seems to work fine on my PC, but the issue is seen on my virtual machine.

When I try to use ping 8.8.8.8 -n 100, it only pings once.

mdmos@MICONIC:/mnt/c/Users/mdmos$ ping 8.8.8.8 -n 100
PING 100 (0.0.0.100) 56(124) bytes of data.

That output is expected behavior when using -n 100 .

Try the following to test connectivity to the actual Ubuntu servers.

ping archive.ubuntu.com -c 4

This is the result

mdmos@MICONIC:~$ ping archive.ubuntu.com -c 4
ping: archive.ubuntu.com: Temporary failure in name resolution
