[Bug 1928687] Re: Avoid infinite loop on EOF on media change prompt

[Brian Murray]

Hello Julian, or anyone else affected,

Accepted apt into hirsute-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/apt/2.2.4ubuntu0.1 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  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-
hirsute to verification-done-hirsute. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-hirsute. 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.

Bug description:
  [Impact]
  The cdrom media change prompt hangs on EOF. This causes the autopkgtest to hang when run in a debian lxd container for unknown reasons related to lxd/systemd isolation likely (it works fine in Ubuntu), but it's also surprising behavior in general.

  [Test plan]
  We did not really come up with a test for this except running autopkgtest -- lxd autopkgtest/debian/$suite/$arch. That being said, the change is minimal, and we do test the positive case in the test suite.

  [Where problems could occur]
  This change is isolated to the handling of pressing 'c' or hitting EOF inside the media change prompt, so any regressions would occur solely within that space. We do not foresee any regressions from the change as intended, as it seems unlikely that "hanging" is what you actually want.
