[Bug 1876495] Re: bash-completion incorrectly shows source package names for APT

[Łukasz Zemczak]

Hello Norbert, or anyone else affected,

Accepted apt into groovy-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/apt/2.1.10ubuntu0.2 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-
groovy to verification-done-groovy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-groovy. 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: apt (Ubuntu Groovy)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-groovy

Bug description:
  [Impact]

  Source packages have been included in apt-cache pkgnames, and virtual
  packages have not been included in apt-cache pkgnames --all-names. The
  former leads to completions autocompleting to source package names
  where they only should complete to binaries.

  [Test case]
  An automated test case is included in the test suite

  test-ubuntu-bug-1876495-pkgnames-virtual

  It verifies that pkgnames does not return source package names, and
  that pkgnames --all-names does return source package names and virtual
  package names.

  [Where problems could occur]
  In the pkgnames command only. If there's a bug, it could exclude or include packages it should not.

  [Original bug report]
  Steps to reproduce:
  1. Have Ubuntu 20.04 LTS installed
  2. Open terminal, enter one of the commands below

  2a.     apt install brisk<Tab>
  2b.     apt source brisk-menu<Tab>
  2c.     apt-get install brisk<Tab>
  2d.     apt-get source brisk-menu<Tab>
  2e.     apt-cache policy brisk<Tab>

  Expected results:
  * The bash-completion should not lead to package name as there are no binary packages named with starting part "brisk" (see https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=brisk )

  Actual results:
  * all commands below get completed to the name of source package - in this example named "brisk-menu"
  (see https://packages.ubuntu.com/search?suite=all&section=all&arch=any&keywords=brisk&searchon=sourcenames). This is absolutely unexpected, as user can not really install this package in binary form.
