The first issue in comment #18 (fsck.mode=skip is ignored if it's last on cmdline) is in progress in bug 1892369 (comment 34) [1]. The second issue (ctrl-c doesn't abort the disk check) is also described there, and unfortunately it's a limitation which was introduced as part of another change, apparently (not a bug), and is no longer an option. ... Currently, to skip the disk integrity check (casper-md5check), please insert 'fsck.mode=skip' before '---' in kernel cmdline (i.e., make sure it's not the last string).

[Bug 1875548] Re: Its not easy to determine how to skip the filesystem check
Forget "quiet", it's whether "fsck.mode=skip" is the last thing on the kernel command line. There is no disk check if there is something after "fsck.mode=skip". I tried "quiet". Then I tried "nomodeset" instead. I tried putting a blank at the end of the line. That was *not* enough to make the "fsck" stop the disk check. I was using the GRUB2 editor, so maybe it would have worked if I really added a blank at the end of the line in the grub.cfg file. Also, Ctrl-C does *not* abort the disk check. Given the way the display crawled through a flock of files before saying it was on squashfs, I'm pretty sure I hit the Ctrl-C before it had started on squashfs -- It just did not pay attention. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875548 Title: Its not easy to determine how to skip the filesystem check To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1875548/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1875548] Re: Its not easy to determine how to skip the filesystem check
I craft my boot device by hand. I'm using files filched from some
Ubuntu distribution (so, GRUB2), lately booting with the ISO file. I've
booted from an external (USB) hard disk, and from thumb drives.
On my external hard drive, I copied vmlinuz and initrd to the ESP
(because on another machine, with Secure Boot enabled, the version of
GRUB2 I filched does not support NTFS filesystems, and I cannot insert
the appropriate module). The ISO file is in a subdirectory of an NTFS
partition. The GRUB2 item is:
set bdir=(${root})/boot
set fsd=/os/boot
menuentry "Ubuntu 20.04.2 64-bit via ISO" {
set gfxpayload=keep
set ubdir=${bdir}/ubuntu200402-64
set isopath=${fsd}/ubuntu-20.04.2-desktop-amd64.iso
linux ${ubdir}/vmlinuz boot=casper iso-scan/filename=${isopath} ignore_uuid
fsck.mode=skip
initrd ${ubdir}/initrd
}
So, GRUB is told to load the kernel and initrd from the FAT-
formatted ESP, while the kernel is told to find the ISO file.
I observed the same behavior with 20.04.1 as with 20.04.2.
I observed the same behavior when booting from a thumb drive as when
booting from a hard drive.
I haven't tried to find a copy of "20.04". Was there such a thing?
Or was 20.04.1 the first released version, the one referred to in all
those posts complaining about the automatic disk check?

Jay: What are you using to make your USB, ISO boot using GRUB2, or a tool like Rufus or mkusb? I can not duplicate your result using Rufus with Syslinux boot in BIOS mode.
