22.04 not installing

I would also suggest that once you have downloaded the file, you verify your download using sha256 before writing it to disc or USB stick to make sure you have a good download.

The verification process is described in detail at the following link:

ISO checksums for kubuntu downloads are found at:

Instead of writing it to a DVD, I strongly suggest writing the ISO image to a USB stick instead. DVD seem to have become less reliable with iso images in recent years, probably due to dwindling usage and user testing, as well as the size of the image.

I strongly suggest to write the image to a USB stick, using the 'Startup Disk Creator' tool found in Kubuntu. You can also just download the USB directly to your hard drive, even if you still plan to burn to a DVD - this is probably better in any case as the hard drive can feed data to the DVD better and faster than data can be sent over USB, which might possibly be part of the problem you are having.

With booting from a USB, you may need to make sure your BIOS is set to boot from USB as the first choice, or use your computer's bootup hotkeys to find a boot drive selection menu. This can differ between computer brands.

Hi

Size seems about right, ubuntu webpage say 3.5 GB, looks as if your ISO is corrupt/broken. You'll need to check the ISO after download.

Have a look in another post I just answered.

I am having difficulty adopting Kubuntu 22.04. At my second attempt I have successfully downloaded (from www.kubuntu.org) the .iso file (size 3,767,502,808 - does that seem correct?) on to a usb stick. Then attempted to burn from that USB stick to a DVD. It ran to 98% and then stopped with 'Write failed : Invalid argument'. I did then try booting from the DVD but got 'Invalid Magic Number' and 'You Need To Load the Kernel First'. Understandable that it would not boot of course so presumably I have erred at an earlier stage - could anybody diagnosed just where, please? The size of the DVD is 3,760,826,612 so less than the .iso - is that normal?
