Cura crashes when trying to use 'Open File(s)' Arch Linux

[wetgravel 1]

I have recently reinstalled my PC with Garuda Arch Linux using their minimal KDE installer. Whenever I open the 'Open File(s)' dialog Cura crashes and quits, the save project and export file dialogs from the File menu work correctly. Trying to Import or Export a material also results in a crash.

 

The logs say:

load non-native FileDialog implementation:
qrc:/qt-project.org/imports/QtQuick/Dialogs/quickimpl/qml/FileDialog.qml:4 module "Qt.labs.folderlistmodel" is not installed
[0m
Fatal Python error: Segmentation fault

 

I had no problems on my previous Manjaro KDE install and have no problems running a much older install of Garuda Arch KDE. I am assuming there is a dependency missing or a Python library not installed but I'm not savvy enough to work out how to fix this.

Are you running the AppImage or did you get a copy from an AUR or something? (Or it could just be in the regular repos, I haven't messed around with Arch in ages). AppImages usually include all the dependencies they need.

 

Also you'd think a KDE install would contain all the Qt libraries you'd ever want 🙂 but I guess if it's minimal maybe not?

 

Being too lazy to set up an Arch VM, just looking in the repos for Debian and openSUSE Tumbleweed ❤️ and the different distros have different packages, so I can't tell you exactly what to search for, but in Debian (actually I can't remember whether that VM is Mint or LMDE so maybe Debian/Ubuntu) you'd probably want to make sure you have (probably being a bit overkill):

qml-module-qtquick-controls

qml-module-qtquick-controls2

qml-module-qtquick-dialogs

qml-module-qtquick-layouts

qml-module-qtquick-window2

qml-module-qtquick2

 

Whereas on my openSUSE install it's a bit more simple:

libQtQuick5

libqt5-quickcontrols

libqt5-quickcontrols2

 

In both VMs Cura runs fine.

 

Basically, just use pacman to search for qtquick and install anything which seems relevant - especially what seems like an all-encompassing package (like libQtQuick5 or qml-module-qtquick2) or anything to do with dialogs or controls.

 

Also, I don't have the Qt 6 versions of these packages installed, so you probably don't need those.

Thanks for the reply, it looks like all the qt dependencies are already installed.

I tried both the Appimage and versions from the AUR , both the same.

 

So unfortunately I still haven't fixed the issue. Luckily drag and drop works for getting models into Cura, but I would like to fix this if I can.

I downloaded a Garuda KDE "Lite" (I've seen full fat distros with smaller downloads) ISO and set up a VM. I was able to replicate your problem but couldn't find a solution. All I found was a deep yearning to punch whoever decided pacman's syntax in the gut. Hard.

[wetgravel 1]

I can never remember the the Pacman commands so always setup zsh aliases called pacsearch, pacinstall and pacremove.

The slightly annoying thing is that the Garuda KDE with the vanilla interface used to be called Bare Bones iirc and was less light, I have it installed on my laptop and it works perfectly.
I also have tried a few a few other Arch Distros with KDE Plasma in a VM, some reproduced the issue and others didn't. I'm now comparing what packages are installed on a fresh install of a distro that did work (Reborn OS) and my Garuda install and hopefully I'll figure out what's missing.

I will mention, using VM's for testing is not really recommended. 
While its possible to get Cura running in a VM.. part of possible issues could be.. that its running in a VM..

Cura does not formally support running in virtualized environments.
As noted here: https://support.ultimaker.com/s/article/1667337917781 

[wetgravel 1]

Well, using a sledgehammer to crack a nut. I ended up just installing all the missing packages that were installed on Reborn OS that weren't installed on mine. Cura started working properly after a reboot.

That's not really what I was doing. Cura was crashing on my desktop PC running on bare metal not in a VM. That's what I needed to fix. I used the VM's to find an Arch distro running KDE that didn't crash Cura so I could compare the differences in installed packages between a distro that worked and one that didn't. And it worked!

I have the same issue on Manjaro i3. 

 

Tried Cura 5.4 and Cura 5.5. Both AppImage and AUR build...

 

Running with strace results in the following just before the crash:

2023-11-01 13:40:19,435 - WARNING - [MainThread] UM.Qt.QtApplication.__onQmlWarning [444]: file:///opt/ultimaker-cura/share/cura/resources/qml/Cura.qml:624:5: QML FileDialog: Failed to load non-native FileDialog>
qrc:/qt-project.org/imports/QtQuick/Dialogs/quickimpl/qml/FileDialog.qml:4 module "Qt.labs.folderlistmodel" is not installed
 

I'm not sure what to install extra, because I have both qt5-declarative qt5-quickcontrols qt5-quickcontrols2 as qt6-declarative

Could you share the list of missing packages, please? 

[wetgravel 1]

I can let you have a list of the packages, Please note that packages I installed are from an Arch KDE install, I couldn't see anything that looked like the likely culprit, so in the end I just installed all of them. A lot of them are particularly for KDE Plasma so you will need to pay attention and filter out the packages that are not relevant to your i3

 

[wetgravel 1]

One or more of the following packages fixed my problem but I don't know which. I don't know if installing any the packages in the following list will work on a Manjaro i3 system and I take no responsibility for any damage you may do to your do to your system.

I would suggest you do what I did but for i3. It looks like RebornOS also does an I3 version, I would download that install it in a VM download and run the Cura appimage and see if the open file dialog doesn't crash Cura. If Cura appears to run correctly get a list of all the explicitly installed packages using

pacman -Qe >reborn_installed_packages.txt

You will need to get that file off the VM and on to your computer, if you haven't set up virtual disks I would suggest email it to yourself from a web email.
Get a list of the explicitly installed apps from your Manjaro I3 system and then use diff to find out what packages are installed on reborn and not manjaro. It's probably worth stripping off the version numbers of the packages in a text editor using find and replace with a regular expression \s.* and replace with nothing.
 

diff reborn_installed_packages.txt manjaro_installed_packages.txt | grep '^<' | cut -c 3- > on_reborn_but_not_manjaro.txt

 

I've got to thank iAsk.Ai for the regular expression and the diff command syntax, I would have had to do it all maunually otherwise

TL;DR: Sorry, I just needed to get this off my chest. Please feel free to ignore me.

And I'm betting you're not the only one. Searching is the most painful, having to regexes (I hate regexes), I ended up installing Octopi because that used plain language and could search the AUR as well as the official repos.

 

Still... I can remember the syntax for zypper fine. And apt. And dnf. /me tries not to begin general anti-Arch rant

Fortunately half the reason I love KDE is that it is infinitely customisable. Although if I wanted something light, I'd be looking for something that runs Xfce instead.

Yes, I'm quoting myself here. But how do you ship a distro without make, nano or even ls and make it take up 1.5GB of an ISO... and demand 29.9GB of hard drive space to install? Normally I only set up my VMs with 16GB and I've only had to increase that for Ubuntu... not that I'm installing a lot of stuff (just a test VM for if someone is having problems with Cura and they're running Ubuntu), just all that comes with it and updates added up quickly.

I couldn't see anything that looked obvious but as the were all installed on a freshly installed Arch KDE install that they weren't going to do any harm to my Arch KDE system if I installed the lot. I had a snapshot standing by to revert to if there were any problems.

Please be a bit more descriptive. Without context that one... what I'm assuming is a shell command... isn't very clear.
