[Bug 1976287] Please test proposed package

[Łukasz Zemczak]

Hello Andrea, or anyone else affected,

Accepted casper into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/casper/1.445.3 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 focal.  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, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

Title:
  casper: qemu instances too small during autopkgtest (potential OOM
  failures)

Status in casper package in Ubuntu:
  Fix Released
Status in casper source package in Focal:
  Fix Committed
Status in casper source package in Jammy:
  Fix Committed
Status in casper source package in Kinetic:
  Fix Released

Bug description:
  [Impact]

  During autopkgtest we are creating VMs with 768MB of RAM, that used to
  be enough in the past, but nowdays we typically require more memory
  and we may trigger some sporadic out-of-memory failures during
  autopkgtest.

  [Test case]

  Run autopkgtest with a recent kernel (e.g., 5.15 or above).

  [Fix]

  Bump up the memory size to 1G.

  [Regression potential]

  We may see regressions in test systems with a small amount of memory
  (in the host / hypervisor), because after this change we need more RAM
  in order to run and complete autopkgtest successfully.
