Dd doesn't work

I was trying to put Fedora on a usb drive, but it doesn’t work:

~/Downloads [1]> sudo dd if=Fedora-Xfce-Live-x86_64-38-1.6.iso of=/dev/sdb
dd: writing to '/dev/sdb': No space left on device
8193+0 records in
8192+0 records out
4194304 bytes (4,2 MB, 4,0 MiB) copied, 0,0341593 s, 123 MB/s

Can we see the output of:

 lsblk -o name,type,size

sda disk 238,5G
├─sda1 part 1000M
└─sda2 part 237,5G

You don’t have a /dev/sdb

But the usb drive was connected, I don’t know what’s happening

It is possible your drive is failing. Thumb drives have a high failure rate.

Or did you do an update and not reboot…kernel esp.
