Comment 5 for bug 2059898

Hi jeff,
Here are the answers:
1: NO network cable connected, installation is successful
yes, after removing network cable, installation is successfully whatever disks(SATA,NVME...) we used.
And when cable disconnected, they can install successfully.

2.Network cable connected and internet is available, installation is successful
The machine's network is our local area network, i think it cannot connect to ubuntu mirror address and cannot connect to internet. And our network proxy is broken, so i am not sure whether it can install successfully when our network can connect to internet. We only confirm when it connect to local area network without internet, it is always failed.

3.Network cable connected, network is available, INTERNET is unavailable (airgapped lab), installation fails
yes in this case, it fails.

I believe from what you described elsewhere #3 is the case you are seeing, because you are in a lab with no external access, is that correct?
yes, correct, and i also confirm #1.
