    How to disable file checking in daily build iso

    Recently when booting from USB containing a recent daily build iso, it takes much longer than before. The reason was due to initrd doing file checking. Is there any way to disable the file checking steps during booting from the LiveUSB?

    None have been documented (that I'm aware of, nor mentioned on community.ubuntu.com where the topic was raised). I've found some flavors harder than others to skip (I've only achieved 'skip' once on Lubuntu for example out of loads of tries... yet have achieved it more than once on far fewer tries on ....)

    Hit escape key during booting, one can see that media check is being executed. Just burn a usb from a most recent daily build iso. This and other warnings/error messages are also very discomforting. There is no need to repeat here--just make a usb, boot from it, and hit the escape key.

    How much longer? Can you provide evidence of that statement?

    Thanks @ping-wu. I had the latest Xubuntu 20.04 daily besides me, so it was easy to test

    Yeah, it's terrible. Relatively speaking, on my laptop 18.04 takes 35 secs, 20.04 recently takes 3 min.
    1st. time it started doing this thought I had a bad iso.

    Edit: today's pending image takes 3:50..
    If you hit s during the bootup it'll skip, exactly when don't know, just tap away for a bit.

    Re: How to disable file checking in daily build iso

    I'm glad error checking was enabled on the (first) 20.04 Beta iso I downloaded. I used a USB and booted up in live mode - all normal it seemed. I attempted to install it and half way through the install I got a error with a bug report request. Rebooting dropped me to the cursed 'GRUB>' prompt. Booted up again and checked the file checking reporting, and noticed one file error. I downloaded another ISO and installed normally with that. How can an ISO downloaded with Qtorrent give me a corrupted file, or does it get corrupted in the finalising process?

    In the recent ISO at least after April 1st when You insert the USB to install you have a window showing the check progress and You have the choice to stop the check.
