Title:
  python3-gpg "1.16.0-unknown" version is incomparable -> dependencies
  always fail

Status in gpgme1.0 package in Ubuntu:
  Confirmed

Bug description:
  The python version of the gpgme version contains "unknown" and is
  therefore not PEP440 order compatible.

  See this example:

    # pip3 freeze | grep gpg
    gpg===1.16.0-unknown

    # pip3 install pstore
    ...
    Successfully installed gpg-1.10.0
    Successfully installed pstore-2.0.0

    # pip3 freeze | grep gpg
    gpg==1.10.0

  
  Key takeways from that example:

  - pstore depends on gpg>=1.10

  - 1.16 SHOULD be higher than 1.10

  - pip installs 1.10 even though 1.16 exists

  - the triple-= (gpg===1.16.0-unknown) means that the version exists,
  but cannot be version compared:
  https://peps.python.org/pep-0440/#arbitrary-equality


  Suggested fix:

  - replace the '-' from `gpgme-config --version` "1.16.0-unknown" with
  a '+'; that will compare as expected;

  - fix so "-unknown" isn't appended.

  
  Apparently, this is caused by insufficient fixes in 0001-avoid-identifying-as-beta.patch

  I've attached a FIXED version, which should fix things.

  Before:

    $ autoreconf -ivf

    $ grep Generated.*gpgme configure
    # Generated by GNU Autoconf 2.71 for gpgme 1.16.0-unknown.

  After:

    $ quilt push 
    Applying patch 0001-avoid-identifying-as-beta-FIXED.patch

    $ autoreconf -ivf

    $ grep Generated.*gpgme configure
    # Generated by GNU Autoconf 2.71 for gpgme 1.16.0.

  
  Versions:

  $ lsb_release -a 2>/dev/null| grep Codename
  Codename:	jammy

  $ apt-cache policy python3-gpg  | grep Installed
    Installed: 1.16.0-1.2ubuntu4
