Client: Ubuntu packages are still built with Qt4

[btittelbach]

[Description updated to match the actual problem]

Expected behaviour

The linux packages should use Qt 5.6 at least

Actual behaviour

Some packages are still using Qt4, and Qt4 bugs (such as the config file being erased) are still reproduced.

Client configuration

Client version: 2.3.2

Operating system: GNU/Linux, Ubuntu 17.04

OS language: English

Qt version used by client package (Linux only, see also Settings dialog): Qt 4.8.7

Client package (From ownCloud or distro) (Linux only):

Distro Client (Built from Git revision 820899 on May 8 2017, 14:16:42 using Qt 4.8.7, built with OpenSSL 1.0.2g 1 Mar 2016)

Installation path of client: /usr/bin/owncloud

Future

As of now I've switched from the Ubuntu distributed package to the ownCloud distributed package. Expect same behaviour but if the bug disappears I'll report on it.

ownCloud ppa version newly installed: (Built from Git revision 820899 on May 8 2017, 14:15:40 using Qt 4.8.7, built with OpenSSL 1.0.2g 1 Mar 2016)

Qt 4.8.7 sounds very weird. @jnweiger You made sure that we get a Qt5 with Ubuntu 16.10. Please apply the same fixes to the 2.3.2 Ubuntu 17.04 builds .

@btittelbach Please wait for @jnweiger 's fix, the please test again from https://software.opensuse.org/download/package?project=isv:ownCloud:desktop&package=owncloud-client

[michaelstingl]

@btittelbach From 2.3.3, ownCloud client for Linux no longer relies on the distribution Qt packages. All platforms will come with own Qt 5.6.2 included.

[jnweiger]

Enforcing qt5 builds on all deb/ubuntu targets. 17.04 is rebuilding fine, right now.
All targets that would only build with qt4 will fail this rebuild, and will remain with qt4. I'll post the list here, so that we know which is which.

[jnweiger]

Rebuild results: All relevant Ubuntu/Debian succeed with some version of Qt5.

@btittelbach Please try again with Ubuntu-17.04 when you see owncloud-client_2.3.2-5.1 on the mirrors. Note the minimum 5.1 rebuild suffix (or later).

[guruz]

@btittelbach Any news? :)

[ogoffart]

I took the liberty to edit the title and description to reflect what the problem actually is

[btittelbach]

@guruz I repeated the things that previously triggered the bug. Does not really count as exhaustive testing, but for everything that i've tried so far the issue seems to be solved! ;-) Thanks!!
