Desktop: Installation on Debian 10 (testing) fails, missing (depricated) dependancy

[pschoond]

Hello,
I tried to install nextcloud-client-l10n_2.5.0-20181111.015125~bionic1_all.deb from the PPA repository:
deb http://ppa.launchpad.net/nextcloud-devs/client/ubuntu cosmic main

I got an error about a failing dependancy: libgnome-keyring0
Searching for this package, I found this bugreport:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892359
It's not released with Debian 10 (buster/testing) because it is deprecated. In the bug report it is advised to use Libsecret instead.

I was able to install the nextcloud client by downloading both dependancies (libgnome-keyring0 and libgnome-keyring-common) from Debian 9. But this is an ugly workaround.

Client configuration

Client version: 2.5.0-20181111.015125
Operating system: Debian 10 (Buster)
OS language: NL
Qt version used by client package (Linux only, see also Settings dialog): 5.11.2+dfsg-4 amd64
Client package (From Nextcloud or distro) (Linux only): http://ppa.launchpad.net/nextcloud-devs/client/ubuntu cosmic main
Installation path of client: default

I think that issues #883 and #990 are addressing the same problem which is that nextcloud-client should use libsecret instead of libgnome-keyring and the package(s) of course depend on this new library.

By referring to Don't Make a FrankenDebian

I'm a little bit concern on how Nextcloud suggest to install their client through PPA for Debian User

I hope in the future Nextcloud will change this practice.

FWIW, some folks at Debian are working on packaging this in Debian itself:

• https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=847613
• https://salsa.debian.org/owncloud-team/nextcloud-desktop

Maybe you want to join forces? :wink:

nextcloud-desktop was uploaded to unstable last week, of course without depends to gnome-keyring.
For me, with libsecret installed, the automation unlock doesn't work, I have to insert the credentials on every start, which is really anoying.

@Micha-Btz Indeed, nextcloud-desktop is not built against libsecret (is libsecret support even implemented in nextcloud client).
Here is a report tracking the issue on Debian side : https://bugs.debian.org/920984

I guess the point here is to have nextcloud-desktop to drop libgnome-keyring0 in favor of libsecret.

[Micha-Btz]

@mxjeff Thanks, this would be easy solved when only libsecret is needed to build.

But nextcloud-desktop nor owncloud-client depend on libgnome-keyring0 nor libsecret. So how this replace should taking place? The credential support is done in libqtkeyring and this is using libsecret.
See also the build log:

Then you probably need libqtkeyring-dev and libsecret-dev while compiling. Can you make a test and compile it from debian git?

As I'm not affected by this bug (using KDE) - this all does not make sense for me to test. I'm still arguing, that this all will not help. As nextcloud-desktop does not depend on libsecret. IMO you need to search why qtkeyring do not connect via libsecret. Maybe 0.9.1 fixes this issue:

https://github.com/frankosterfeld/qtkeychain/blob/master/ChangeLog#L6

I would recommed for affected people to try out built qtkeychain 0.9.1 and if the issue is gone with that, that we fould the source of the issue.

[Micha-Btz]

I have tried it aft the update to libqt5keychain1 0.9.1-1 in unstable today. Makes no difference.
And I also get no output with dbus-monitor

[Micha-Btz]

Can give someone some hints how to debug this? Logdebug from client is also not really helpfull.

@Micha-Btz: well you need to use standard linux debug tools like strace and gdb. I used those and for Debian I found a workaround:
ln -s /usr/lib/x86_64-linux-gnu/libsecret-1.so.0 /usr/lib/x86_64-linux-gnu/libsecret-1.so

but why the hell qtkeychain is trying to access libsecret-1.so instead of libsecret-1.so.0, I have no idea. An application should never access a .so lib.

See https://bugs.debian.org/922489

[Micha-Btz]

For me it is working now. I have to install and run seahore, before nc client starts.

In Debian 10 Buster, the Nextcloud client is actually available straight from the default repositories.

sudo apt install nextcloud-desktop
