get Dropbox working

[frarude]

Unable to activate Dropbox external storage. Always error message "Fetching request tokens failed. Verify that your Dropbox app key and secret are correct."
App code and secret correct and verified. CA certs are valid and up-to-date.

Solution:

remove debian package php-dropbox and install files and folders
(/usr/share/owncloud/) apps/files_external/3rdparty/Dropbox
from git instead.
Modify apps/files_external/lib/dropbox.php and external/ajax/dropbox.php to contain
require_once DIR.'/../3rdparty/Dropbox/autoload.php';
instead of the relative path. (This is a relevant difference between debian package and git)

Steps to reproduce

1. debian system (sid)
2. install apache, php, (and minimum additional: php-dropbox )
3. install owncloud 7
4. follow steps to activate a Dropbox external

Expected behaviour

external_files Dropbox should work

Actual behaviour

It is not possible to activate a Dropbox synchronization

As far I can see you're using packages by the Debian maintainers. Those are unsupported by us, if you cannot experience this bug with the official packages available via http://owncloud.org/install/#instructions-packages I'm going to close this issue and ask you to get touch with the Debian maintainers.

[karlitschek]

@LukasReschke Do you have evidence that the packaging might make a difference?

remove debian package php-dropbox and install files and folders
(/usr/share/owncloud/) apps/files_external/3rdparty/Dropbox
from git instead.
Modify apps/files_external/lib/dropbox.php and external/ajax/dropbox.php to contain
require_once DIR.'/../3rdparty/Dropbox/autoload.php';
instead of the relative path. (This is a relevant difference between debian package and git)

That looks PRETTY much like a packaging problem ;-)

[LukasReschke]

Additionally, really, we already have way too many issues just with our own distribution. If other distributions break it by manually patching things we shouldn't care about that too much…

See

core/apps/files_external/lib/dropbox.php

Line 25 in 3ff1f87

require_once __DIR__ . '/../3rdparty/Dropbox/autoload.php';

- we're doing it correctly…

Subject: Adapt Dropbox path

The Debian package depends on the needed classes instead of embedding
them, i.e. php-dropbox.

That's within their patches.

[karlitschek]

Ok. Makes sense

[frarude]

I am aware that this is not an owncloud fault but I think many people do search here. For all of them I wrote this "Issue".

[DavidPrevot]

Upstream bug tracker is not the appropriate place for Debian specific
issues. Please, file a bug report in the BTS, preferably using reportbug.

https://www.debian.org/Bugs/Reporting

People using the Debian package, as distributed by Debian, should look there:

https://bugs.debian.org/owncloud

[DavidPrevot]

[Sorry for continuing this thread, but I didn’t get any answer by mail or bug report]

@frarude I updated php-dropbox to fix this issue, can you please give it a
try and report back that it works as expected (preferably via a bug report)?

https://people.debian.org/~taffit/php/php-dropbox_1.0.0-3_all.deb

Thanks in advance.

Regards

David
