[Bug 1995790] Re: regression: ?garbage does not work correctly in install commands

[Launchpad Bug Tracker]

This bug was fixed in the package apt - 2.7.10

---------------
apt (2.7.10) unstable; urgency=medium

  * pkgcachegen: Use placement new to construct header to make
    valgrind happy when we hash/write out padding bytes
  * Add Conflicts: apt-verify.
    The APT team is very concerned about the encroachement of its
    namespace and the impact on security of its file verification
    process. We have expressed those concerns in the ITP bug, but
    the package was nonetheless uploaded and accepted, so we have
    to take this extraordinary step to protect our users.

Bug description:
  The awesome apt has a some wonderful tips on their EXAMPLES section
  (printed below). The choice of name to "garbage" might not have been
  the best but the function is extremely useful.

  $ man apt-patterns | sed '/EXAMPLES/,/^[^ ]/!d;/^[^ ]/d'
         apt remove ?garbage
             Remove all packages that are automatically installed and no longer needed -
             same as apt autoremove

         apt purge ?config-files
             Purge all packages that only have configuration files left

         apt list '~i !~M (~slibs|~sperl|~spython)'
             List all manually-installed packages in sections matching libs, perl, or
             python.

  Lets mark a package as automatically installed, and use the examples.

  $ sudo apt-mark auto shotwell
  shotwell set to automatically installed.

  $ sudo apt remove ?garbage
  Reading package lists... Done

  The following packages were automatically installed and are no longer required:
    libraw20 shotwell shotwell-common
  Use 'sudo apt autoremove' to remove them.
  0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

  $ sudo apt autoremove

  The following packages will be REMOVED:
    libraw20 shotwell shotwell-common
  0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
  After this operation, 9.806 kB disk space will be freed.
  Do you want to continue? [Y/n] N
  Abort.

  Apt-patterns works as it should everywhere else, as far as I can see,
  it works wonders with ie `apt list '~g|~c'` and many other
  applications. I used `apt purge '~g|~c'` successfully in Ubuntu 20.04
  for years, so I feel this is a regression.
