Disable Integrity Check On Ubuntu Server 20.04.1 ISO?

server system-installation disk-check

I was plagued with this issue as well, would easily take 40+ minutes for the check to finish when using IPMI virtual media.

I believe I've found a workaround for now.

Spam press Ctrl+C as soon as you see the purple screen appear after booting from ISO. You should see the following screen after pressing Ctrl+C:
Select your language, press Enter. Then, once the screen is at Install Ubuntu Server, select F6 Other Options:
Press Esc to close the dialog box in the bottom left corner. At this point, you should be able to type on the line that starts with Boot Options.... Replace quiet with fsck.mode=skip, then press Enter:

At this point you should be able to boot without disk verification which is very fast over an IPMI-mounted disk.

  No. This is when booting from virtual media (imitating CD) on a server when trying to install the OS.

  Are you installing onto bare metal? Or into a VM or container? Your output indicates that your system disabled caching, so yes the check is going to take a long time.

  I went out shopping and it finished. Now I am installing. Yes - on bare metal. Would be good to know how to skip this. Also there appears to be 20.04.2 installer, which is being downloaded now. Strange. It is not available on the ubuntu site, yet.

At the grub prompt for install ubuntu server you need to hit 'e' then add "fsck.mode=skip" immediately before "quiet" (add a space before and after "fsck.mode=skip") then hit F10 or ctrl+x, I tried adding it to the very bottom and it didn't work, more info here : bugs.launchpad.net/ubuntu/+source/casper/+bug/1892369/commen‌ts/…
