Main dialog window does not open - Ubuntu

[RomeroVerde]

Expected behaviour

Main dialog window should open when clicking either on:

• Open main dialog or
• See conflicts in setting window

Actual behaviour

Main dialog does not open.

Steps to reproduce

1.a Click in Next cloud logo > Open main dialog
1.b (from settings window) Click on see conflicts.

Client configuration

Client version: Desktop 3.4.0 (Ubuntu)

Operating system: Ubuntu 20.04

OS language: English

[ajoana]

Same here with current Mint Mate 20.2 in German.

[RomeroVerde]

It appears to be the same as:
#4017

[Apromixately]

I have the same issue with the settings window. Should I create a separate issue?

[schworak]

Appears to be the same for Mint. I have nextcloud-desktop 3.4.0 installed and the "open main dialog" does nothing.

[k3tan172]

Appears to be the same for Mint. I have nextcloud-desktop 3.4.0 installed and the "open main dialog" does nothing.

Same for Pop!_OS. "Open main dialog" does nothing.

[mrmatteastwood]

Confirmed on Linux Mint 20.2 Cinnamon. Nextcloud client 3.4.0 from nextcloud-devs/client PPA.

[MegaV0lt]

Bug still exists with 3.4.1 on Linux Mint

[k3tan172]

Can confirm bug still exists with 3.4.1 on Pop!_OS. Interestingly, if you try the AppImage for 3.4.1, it works as expected.

[bugariu]

Bug still exists on Kubuntu 20.04

[MauroFoti]

Same in linux mint 20.1 with client 3.4.1. Weirdly enough, the bug does not replicate with the appimage (3.4.1) downloaded from https://nextcloud.com/install/#install-clients

[bugariu]

Wondering if it has something to do with commit 12c6d6e (esp. line 63:

_trayEngine->setNetworkAccessManagerFactory(&_accessManagerFactory);

Had myself problems using setNetworkAccessManagerFactory on Kubuntu 20.04 with stock Qt 5.12 since according to https://github.com/KDE/kdeclarative/blob/master/src/kdeclarative/kdeclarative.cpp#L88 the own NetworkAccessManagerFactory gets deleted. When I was using Qt 5.14 from /opt there was not such a problem.

This may explain why the appimage works (own Qt libraries?)

I would test it myself, but I can't compile on Ubuntu 20.04

[resoli]

Same here (Ubuntu 20.04)

[allexzander]

We will release a fix in 3.4.2. Ubuntu 20.04 https://pkgs.org/download/libqt5quick5 comes with Qt Quick 5.12 while we need 5.15 which comes in the most recent Ubuntu. For now, the only way is to either use 3.3.6, or use 3.4.1 via AppImage/flatpak/snap.

[k3tan172]

Upgraded to 3.4.2 via apt package manager and still the same issue. "Open main dialog" window does not appear.

[mad73923]

Same here :(

FWIW, I discovered that if you leave everything from the repos installed, but then download the AppImage and run that, everything works perfectly. Both the dropdown as well as file manager integration (Nemo, in my case) continue to work.

This is on Linux Mint 20.2.

The AppImage puts its config files into the same location as the repo version, so what I did was, I un-checked the "launch on system startup" option in NC's settings and manually put the AppImage into my startup programs.

[despens]

If the client is dependent on a library that is not available in a LTS version of a distro as popular as Ubuntu, perhaps you could distribute it via Flatpak or snap instead?

[MegaV0lt]

Menu and language still not working with 3.4.2 on Mint Cinnamon 20.3

[jurgenhaas]

Confirmed, just updated to the packages version 3.4.2 on Ubuntu, the client works but the popup still doesn't show up.

[mrmatteastwood]

The client is, in fact, available as a snap or flatpak. To my understanding, though, you can't have file manager integration if you run either of these.

[despens]

@mrmatteastwood For the AppImage version the file manager integration works just fine.

The snap release of the desktop client is an "unofficial" build and as far as I understand from the description depends on Ubuntu Core instead of providing its own libraries (so the wrong QT version would still be used). It also states it doesn't support file manager integration. So for now using the AppImage is probably the best compromise.

[MegaV0lt]

there is no 3.3.6 for focal in the ppa

[NielBuys]

@MegaV0lt I want to reverse to a version that has the dialog working. The ppa only shows version 3.4.2. So that is why I am requesting / asking if I can get a version in ppa to reverse to. Thanks for the reply.

Why the nextcloud team do not fix this AWFULL bug ?
i cannot add another NC account.

@ledufakademy I had the same problem, and the AppImage provides a good workaround. Check out my post above:
#4069 (comment)

Just need to download the AppImage here: https://github.com/nextcloud/desktop/releases/download/v3.4.2/Nextcloud-3.4.2-x86_64.AppImage

Then mark as executable in the file properties, run, add your account. If you like, you can also replace the repo version with it: just close the AppImage, run the regular Nextcloud client that you already have installed, go to Settings and disable "Launch on System Startup". Then, open "Startup Applications" (in Mint, might be called differently in other distros) and add the AppImage there manually.

I confirm that this workaround is working (Linux Mint 20.3 -XFCE). However, it simply should be working when you install it (from repo/PPA) or fixed soon. I also notice that the font in the main dialog is tiny and the settings dialog themed properly.

[mvv588]

Same issue with v3.4.3, we deploy software using apt to our (100+) users on Ubuntu 18/20.04, the snap version is not usable, using the Appimage is not feasible. Please fix the version in the ppa, it is going to take several years before our users migrate to Ubuntu 22.04 after it comes out, thank you.

[MegaV0lt]

3.4.3 still defekt, No Main Dialog opening on click and not in systemlanguage.
how can i install the 3.3.6 Version. It is not in the ppa

[mgallien]

sorry to hear that has not been solved
can you all confirm that you get the package from a PPA archive and confirm the version of the package you use ?
we have provided patches to allow packagers to downgrade the requirement on the Qt version
packages from us only are provided as AppImage that should be fully working and are built against the required Qt version (5.15)
the proper Qt version is unavailable on Ubuntu 20.04 and hence require extra patches to be built
we have provided help there

[jurgenhaas]

Yes, I can confirm that I've installed 3.4.3 from PPA on Ubuntu 20.04 and the main dialog still doesn't show up.

[mgallien]

@ivaradi could you have a look apparently people still have troubles running desktop client 3.4 version on Ubuntu 20.04
@jurgenhaas if possible could you upload us the debug archive that you can generate from the desktop client right after a start of it ?
that will allow to figure out what is missing in the current package

[jurgenhaas]

@mgallien there is quite some sensitive data in that log. What exactly are you looking for?

[ivaradi]

I think the bug has something to do with the fact that Qt 5.12 is used on Ubuntu 20.04 (while the code itself expects Qt 5.15). So perhaps there is some code related to the main window that compiles on Qt 5.12, but does not work as expected. I am not really familiar with Qt, but if you can give me some hints as to where to look in the code, I might be able to experiment.

As far as I understand, the "Settings" window continues to open fine for everyone using Right-click >> Settings.

So would that not be simple and make sense to just replicate the functionality of the main dialog within the "Settings" window?

For example :

• In the top banner of the Settings window, have a link to adding a new account, to the right of the list of current accounts (not being able to add new NC accounts IS a big stumbling block)
• add a tab for Conflicts
• etc.

The client would remain usable for everyone, whether or not they have the current QT bug and any possible future bug to the same effect.

Could we have that?

YES PLEASE. I 1000% agree!

Thank you so much for your great work

I have this problem again when using the repo version of the nextcloud client. I wonder if this has to do with the version of Qt on my system (see config below).

It's been broken at least since client version 3.5.1, possibly before and was definitely working fine with 3.4.2. However in the meantime Qt has updated so unsure whether the bug is from the update on the client or from the update in Qt. The flatpack version of the client works completely fine.

Nextcloud Desktop: 3.5.2 from stable ppa
Operating System: KDE neon 5.25
KDE Plasma Version: 5.25.3
