[Bug 1840122] Re: System fails to reboot from live session or ubiquity-dm - squashfs_read_data failed to read block

Tue Jan 28 11:37:23 UTC 2020

Hello Jean-Baptiste, or anyone else affected,

Accepted casper into bionic-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/casper/1.394.3 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  To properly test it you
will need to obtain and boot a daily build of a Live CD for bionic.
Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: casper (Ubuntu Bionic)
       Status: Confirmed => Fix Committed

** Tags added: verification-needed verification-needed-bionic

Bug description:
  Last known good image: Eoan Ubuntu Desktop 20190715

  Similar results started to happen with new linux-hwe kernel based on
  eoan for 18.04.4 release.

  Test Case:
  1. Boot eoan desktop to a live session
  2. Wait a couple of minutes until snapd settles
  3. Reboot the system from the system menu or from the command line

  Expected result:
  The system reboots

  Actual result:
  The systems fails to reboot or shutdown and displays some errors about failing to unmount /cdrom and squashfs errors in a loop.

  Unmounting /cdrom...
  [FAILED] Failed unmounting /cdrom.
  [  OK  ] Started Shuts down the "li…" preinstalled system cleanly.
  [  OK  ] Reached target Final Step.
  [  OK  ] Started Reboot.

  This also causes daily tests to fail and is reproducible in a VM and
  bare metal booted in legacy bios mode
