PVE 8.1-1 installation fails with unsquashfs-error

Wanted to add my 2cents -- could not get 8.2 to work. Tried all the same things as everyone else in this thread. Tried 7.4, worked first try (booting from same USB drives as 8.2 also).
 
I just find out that installation did work with other usb SD card reader but other give me this error. So maybe there is something related to SD card readers too?

Can confirm. Had this issue and once I flashed to a regular flash drive it worked no problem. Tried 3 times with a card reader and no luck. Strange issue but glad the fix was easy.

I know this is a bit dated, but I thought I'd post my solution. I encountered this error when using a USB stick. I saw a solution to install 7.4 and then upgrade, which I did but I didn't want to stop there. I thought about it and saw some folks said to use a different or a new USB stick. I had a USB 3.0 HDD enclosure so I put in a 500GB SSD I had around (overkill I know) and wrote the 8.2 image to the HDD using the PI imager. It installed flawlessly. Same image as failed on the USB stick.

Ran in to the same issue and found this thread. You guys nailed it down to the USB stick, so I used Diskpart to make sure that every single partition was deleted before I wrote the installer on with Rufus, and then it worked just fine.
