Installation media self-check: weird reply

Installation media self-check is giving me a reply that makes no sense. It is not saying success or failure; it’s saying:
Please make sure your installation medium is available. Retry?

I’m using the net install on a USB flash drive.

So, is it not smart enough to know it’s on USB, and trying to verify a CD that it can’t find?

I see reports of this error related to Wifi, but I’m plugged-into the LAN.

Confused,
Lance

That’s the problem. It is looking for a CD or DVD to check.

My advice: don’t do media checks when you are using a USB. But do validate your download with md5 or similar checksums before you write it to the USB.

It is impossible to validate the USB stick. The image file can be
validated before it is placed on the USB stick, but not later — at least
on the lives, after the first boot, its partition table is modified,
adding a writeable partition. Thus changed, it no longer can pass the
check, which anyways, only tests CD/DVDs.

I don’t know if they can redesign the test, or at least give a message
that USB sticks can’t be tested.

A writeable partition is added for live USB. But the OP was about the NET install image, and I’m pretty sure that doesn’t add a writeable partition.

However, I agree that it would be good if the test could be fixed to either give a sensible message or to even check just the one partition that should not change.

The actual image can be different for each class of device. the test is for CD/DVD only. That is mainly because burning a dvd/cd is just not all the reliable. Copying an image to a drive is very reliable.
