No "open file" dialogue

[RealCommerzpunk]

Good day, after updating the container to and having Cura 5 inside, there is an issue with openin files. When I click "open" no windows opens to choose a file. The only workarrond I found is, to rename my .stl files to one from the "recent" list, it will open then from picking it there.

Would you please investigate?

Hi @RealCommerzpunk ,

This is likely due to https://github.com/Ultimaker/Cura/issues/12266. I tried a few things locally to no avail so we might have to follow along on the upstream bug.

[RealCommerzpunk]

Thank you for investigating! I now just hope for a quick solution by cura, because I cant use the common workarrond "drag and drop into cura" because its a docker, lol. ;)

[helfrichmichael]

That's no problem, actually!

Reduce the window size of Cura in the docker or minimize temporarily. Then you can right click the desktop and click "File Explorer" visiting /prints should take you to your GCODE and STLs.

Thanks first of all for the Docker image. But is there also another solution for exporting the G-code? Opening is quite simple via drag and drop. Thanks!

Hi, could you try this WO:

sudo apt-get install xdg-desktop-portal-gtk
dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORITY

It should fix the problem of not showing the open file window.

I tried, but i cant run the commands. I tried 2 ways: The "console" window from the unraid docker menu and second, the "terminal" window in the running GUI. Both result with "sudo: not found".

Then I tried the command without "sudo". Inside the GUI it results with "E: Could not open lock file /var/lib/dpkg/lock-frontend - open (13: Permission denied) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), are you root?" From unraid "E: Unable to locate package xdg-desktop-portal-gtk"

So I cant help, what am I missing?

@RealCommerzpunk

On host: sudo docker exec -it --user root <CONTAINER_NAME> /bin/bash

Then in container:

apt-get update
apt-get install xdg-desktop-portal-gtk dbus-x11 -y
service dbus start
export $(dbus-launch)
dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORITY

Next open web browser, right click -> select terminal and paste:

export $(dbus-launch)
dbus-update-activation-environment --systemd DBUS_SESSION_BUS_ADDRESS DISPLAY XAUTHORIT

And everything should working.

@helfrichmichael Do you think about adding this WO to your Dockerfile? It should resolve the problem until cura resolves it on their site.

Unfortunately on the new container with Cura 5.1.1 fix is not working.

@update It is more complicated now. You need to do all that steps above but then run cura using command: LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 /bin/sh -c /cura/squashfs-root/AppRun

I cannot find but in one of the open issue on cura was information to use: Ultimaker-Cura-5.1.1-linux-modern.AppImage for updated linux distros instead of normal version: Ultimaker-Cura-5.1.1-linux.AppImage That version should work.

Thanks to https://github.com/Ultimaker/Cura/issues/12266#issuecomment-1274861668 I think we have a viable fix. Testing now and if all is good, I'll push shortly.

[helfrichmichael]

Thanks for the patience!

https://github.com/helfrichmichael/cura-novnc/actions/runs/3238503566 is rolling out with the fix now. I'll mark this as resolved.
