[Bug 1986781] Re: [Ubuntu 22.04]cloud-init failed to complete after 10 minutes of waiting was shown during Installation via iDRAC Virtual Console
This bug was fixed in the package casper - 1.470.2
---------------
casper (1.470.2) jammy; urgency=medium
[ Dan Bungert ]
* d/casper.casper-md5check.service: order it After=multi-user.target.
This should allow us to reach multi-user.target sooner, especially for
users where the md5 check is slow. (LP: #1986781)

Bug description:
[Impact]
* Users that install Ubuntu Server through slow
media (eg, virtual optical drive over network,
which may be common on enterprise deployments)
might hit the following subiquity startup error:
'cloud-init failed to complete after 10 minutes of waiting'
* (That in addition to 10 minutes of waiting themselves.)
* This happens because casper-md5check.service is
(slowly) verifying the integrity of install media,
which blocks `multi-user.target`,
which blocks `cloud-final.service`,
which blocks `cloud-init status --wait`
which is used in subiquity / `waiting on cloud-init`).
[Fix]
* The adopted solution (merged on lunar) is simply
not to block `multi-user.target`, but rather run
_after_ it.
[Test Steps]
For a synthetic reproducer of slowness of casper-md5check:
* boot with `break=init` to break into initramfs-tools
before exec() systemd.
* chroot /root /bin/bash
* edit /usr/lib/systemd/system/casper-md5check.service
* prepend `strace --inject read:delay_enter=5s` to the
command in `ExecStart`, to introduce a 5 secs delay
to every read() syscall performed by casper-md5check.
* exit twice (chroot, initramfs shell) to resume boot.
See comment 37 for examples.
[Regression Potential]
* Functionality related to install media integrity check.
* Users with corrupted install media might not realize
this until later on; but this is rarely the case and
even w/out the fix, there's a lot that runs _before_
we even get to casper-md5check, so they may (still)
see errors early anyway.
* There's a cosmetic glitch in the proposed solution:
the systemd line when casper-md5check finishes
shows up on top of subiquity's menu (screenshot):
"[ OK ] Finished casper-md5check Verify Live ISO checksums."
Dan Bungert mentioned this is known and should be
addressed in a future change to subiquity, and is
not supposed to block the SRU for Jammy / 22.04.2.
