It's been a few months since I did this, but the technique still works just fine.

I have the same problem when I create a usb stick of Fedora 32 but only on some newer machines.

I don't think it is a bug but this shows how to fix it:

https://bugzilla.redhat.com/show_bug.cgi?id=1768498

Had to access the stick offline on another machine, then , I edited the /etc/lvm/lvm.conf file and changed these two parms to these values:

external_device_info_source = "udev" fw_raid_component_detection = 1

it now boots fine on all the machines (one that hung on the Monitoring LVM and ones that did not)

That is interesting.

I have a USB stick that I can edit so I will try this and report back.

I did what was suggested, boot a Live CD and install onto another USB. Because the sticks I have are only 8GB I need to use a Fedora Server live CD to get the install size to fit. KE did not fit for example.

I got as far are replacing lvm vgchange --monitor y with sleep 30. And the stick then boots.

I ended up getting an USB SSD for this, the USB sticks where too small and very slow.

It did not help that I tried to do a dnf update and 24 hours later it was still going and then the kernel paniced.

Using the SSD I reproduced the problem and you where quite right adding the two lines to lvm.conf fixes the problem.

Unless there is a reason not to add thoses lines I think this is a bug.

I'm going to discuss on Fedora devel list.

 FWIW, some years back I did (more than once) install Fedora  onto
 a USB stick using an normal install procedure. all I had to do was
 be sure to specify the right device for the USB stick so I didn't
 wipe out the installed system on the computer.

By "normal install procedure" I assume you mean you were able to boot some installation media. Since the OP can't boot the live media, the "normal install procedure" isn't available. It may be possible to create a new ISO image with extra grub options like [2]https://www.askapache.com/linux/linux-debugging/

I was doing it before the live system options were common, so it was just boot up an install disk and let the installer run, being sure to use the right destination device. I don't know why a live usb would fail to install on a USB stick, as long as it isn't the same one you've already booted. Also, last I noticed, there were installation media other than the live ones.
