** Description changed:

  Samba 4.10.0[1] is the first samba release to completely support
  python3. It is a goal of Ubuntu to remove python2 from the desktop
  images (see bug #1440381), and this release of samba, together with the
  mandatory dependency updates it warrants (ldb, tdb, talloc and tevent),
  allow for that to happen.

  talloc FFe: https://bugs.launchpad.net/ubuntu/+source/talloc/+bug/1818522
  tevent FFe: https://bugs.launchpad.net/ubuntu/+source/tevent/+bug/1818523
  ldb FFe: https://bugs.launchpad.net/ubuntu/+source/ldb/+bug/1818525
  
  Samba 4.10.0 is not yet released, though. The current release is
  4.10.0rc4. The final release is expected for March 19th, 2019 (see [1]:
  it slipped, as it was supposed to be released on March 5th).
  
  Release notes for the 4.10 branch are at [2]
  
  Considerations:
  - We are going ahead of Debian with this change
  - python2 bindings will be dropped from the samba package, in favor of py3 
only ones. It is possible to build with both, but the current packaging would 
have to be changed because, among other things, samba-libs has python 
dependencies. We would need to move those to another package otherwise 
samba-libs would depend on both python2 and python3, which defeats the purpose 
of what we want
+ - reverse depends for python-samba (the py2 package);
+ $ reverse-depends python-samba
+ Reverse-Depends
+ ===============
+ * samba
+ * samba-common-bin
  - new python3-* packages will result from this effort: python3-samba, 
python3-ldb, python3-talloc
  - this is the first release of samba that supports python3. Bugs can be 
expected
  - samba "dot-zero" (.0) releases might contain bugs that are quickly fixed in 
point releases. We might have to do such updates before Disco releases.
  - samba 4.10.x is the last series of samba that will support python2
  - sssd needed a patch to fix an FTBFS with samba 4.10. It's in the bileto ppa 
(see below) and I proposed it for disco already 
(https://code.launchpad.net/~ahasenack/ubuntu/+source/sssd/+git/sssd/+merge/363940).
 Turns out sssd was already an FTBFS in disco due to the krb5 1.17 update 
(which I also fix in that MP). UPDATE: it is in disco now.
  
  We believe there is greater risk in postponing this change for disco+1
  than doing it now, and flushing out the bugs in preparation for the next
  LTS.
  
  FFe bugs for the samba 4.10 dependencies have been filed as well.
  
  Ongoing work for this update is being tracked in

  A diff between what is in disco, and the proposed packages, can be
  obtained with git by running diffing against the ubuntu/devel branch.
  
  Or with git-ubuntu:
  sudo snap install git-ubuntu --edge --classic
  git ubuntu clone <package>
  cd <package>
  git ubuntu remote add ahasenack
  git checkout disco-<package>-<version>
  git diff pkg/ubuntu/devel
  
  PPA with test builds:
  https://launchpad.net/~ahasenack/+archive/ubuntu/samba-4.10/
  
  Bileto ticket is green with all these packages:
  https://bileto.ubuntu.com/#/ticket/3672
  
  The gvfs failure is a badtest in disco already.
