Hi Nicolas,

This was a comment on the Debian bug report; I'm suggesting uploading
my changes to the Debian anki collab-maint repository.  It's too late
for anki to get into stretch, as we are now in quite deep freeze, and
it has been removed from testing.  But the version I have created,
especially when 2.1.0 has stabilised, should be able to be backported
to backports.  In the meantime, it can be uploaded to unstable (at
least once my new package, python3-send2trash, which is needed by anki
2.1.0, has been processed through the NEW queue; this can also easily
be backported to stretch-backports).

Best wishes,

   Julian

I'm not an Anki dev, just a user, I don't know about their repositories.
As a Debian user, at the moment I'd rather see Anki removed from Debian.
It doesn't look like we'll have a usable release before the stretch
freeze, but by all means, contribute your code upstream. I hope a stable
Qt5 Anki will appear in backports rather sooner than later.

I have managed to create a working Debian package based on the latest
alpha.  Would you like me to send the changes to the collab-maint
repository?

Best wishes,

  Hi,

I'm posting a modified version of Richard's Dockerfile for people using
fcitx and Chinese.  I know nothing about docker but the configuration
appears to be running and can be used as the starting point for others.

  Best,

This is not a good solution for everyone, but I'm now running Anki
inside a Debian Jessie Docker container. See here for how to do it:

There is another Qt5 repository at https://github.com/intact/anki/, it
has the same issues you mentioned. After removing my conflicting plugins
and creating a new profile I was able to use it.

Right, until there's a Qt5 port, little can be done. I have actually
experimentally ported it a while ago and ran into a few significant
problems. I need to update my code to the latest upstream git and submit
it for consideration.

The significant problems are that it has plugins and Qt4/Qt5 don't work
together in the same program. The other big problem is that the
configuration is a serialized dump of some Python data and some Qt4
package name is encoded in it. Loading old configuration in the Qt5 port
will make it crash.

So yeah, even if I submit my port ASAP there are still some showstoppers
to iron out.

Dear Maintainer,

as said in the last response, anki is not usable at all anymore. Raising

This has severe impact on people, please at least respond so that we 
know what to expect (or not) and when.


Thanks for your work,

Dear Maintainer,

it seems like anki is not usable any more. I guess this was expected but
I'm wondering if there is a plan for the future. Severity should
probably be bumped to grave.

Bug#784612: [anki] Qt4's WebKit removal

[Dmitry Shachnev]

Source: anki
Severity: wishlist
User: debian-qt-...@lists.debian.org
Usertags: qt4webkit-removal
Control: block 784513 by -1

Hi! As you might know we the Qt/KDE team are preparing to remove Qt4's WebKit
as announced in [announce]. Your package seems to be using it via PyQt4's
QtWebKit module.

[announce] 
https://lists.debian.org/debian-devel-announce/2015/05/msg1.html

Basically we are about to get the last Qt4 point release and upstream is
migrating from WebKit to Blink in the Qt5 series, so we won't have much upstream
support for maintaining Qt4's WebKit (Qt5's WebKit is expected to stay supported
until Qt6).

In order to make this move, all packages directly or indirectly depending on
the Qt4's WebKit library have to either get ported to Qt5 or eventually get
removed from the Debian repositories.

Therefore, please take the time and:
- contact your upstream (if existing) and ask about the state of a Qt5 
  port of your application
- if there are no activities regarding porting, investigate whether there are 
  suitable alternatives for your users
- if there is a Qt5/PyQt5 port that is not yet packaged, consider packaging it
- if both the Qt4 and the Qt5 versions already coexist in the Debian 
  archives, consider removing the Qt4 version

= Porting =

Some of us where involved in various Qt4 to Qt5 migrations [migration] and we
know for sure that porting stuff from Qt4 to Qt5 is much much easier and less
painful than it was from Qt3 to Qt4.

We also understand that there is still a lot of software still using Qt4. In
order to ease the transition time we have provided Wheezy backports for Qt5.

Don't forget to take a look at the C++ API changes page [apichanges] and the
PyQt4 vs PyQt5 differences page [pyqtchanges] whenever you start porting
your application.

[migration] http://pkg-kde.alioth.debian.org/packagingqtstuff.html
[apichanges] http://doc.qt.io/qt-5/sourcebreaks.html
[pyqtchanges] http://pyqt.sourceforge.net/Docs/PyQt5/pyqt4_differences.html

For any questions and issues, do not hesitate to contact the Debian Qt/KDE 
team at debian-qt-...@lists.debian.org.
