Kubuntu 22.04 missing libwebkit2gtk-4.0.so.37 when running AppImage

[Guswilly]

Describe the bug Steps taken: Downloaded zip file, extracted, properties changed to executable, then Run in Console returns: /tmp/.mount_BambuSdizE6Q/bin/bambu-studio: error while loading shared libraries: libwebkit2gtk-4.0.so.37: cannot open shared object file: No such file or directory

Ran updates, and I have tried with the same error: sudo apt install libfuse2 Unfortunately Web based content is overloaded with the above fix making it hard to find a fix.

Desktop (please complete the following information):

• OS: Kubuntu 22.04

Did you install libwebkit2gtk-4.0? I had to install webkit2gtk4.0 package on Fedora to get rid of that error.

Fedora: dnf install webkit2gtk4.0 (K)Ubuntu: should be apt install libwebkit2gtk-4.0

It might be a different package name as searching online it seems like it has libwebkit2gtk-4.0-37, but it might be different for your specific version of kubuntu.

Same issue on manjaro stable.

pacman -Ss libwebkit2gtk
extra/webkit2gtk 2.38.4-1 Web content engine for GTK extra/webkit2gtk-4.1 2.38.4-1 Web content engine for GTK extra/webkit2gtk-5.0 2.38.4-1 Web content engine for GTK

[Guswilly]

Thanks for the help. I tried this all again and found that I had a typo in the library name, a simple . versus a - (libwebkit2gth-4.0.so-37 is the correct name).

Now it works.

[khumarahn]

Same here on gentoo. I have net-libs/webkit-gtk-2.40.1-r410 installed. I don't undestand how to fix this

[Krutonium]

This really should be packed into the AppImage

[lordfiSh]

Same Problem on the Steam Deck (Arch Linux) /tmp/.mount_OrcaSlPfBnnd/bin/orca-slicer: error while loading shared libraries: libwebkit2gtk-4.0.so.37: cannot open shared object file: No such file or directory

#1841 and #185 have the same issue

[Cypher1]

For me the following packages were missing:

webkit2gtk4.0-2.40.0-2.fc38.x86_64
mesa-libOSMesa.x86_64

i.e.

sudo dnf install webkit2gtk4.0-2.40.0-2.fc38.x86_64 mesa-libOSMesa.x86_64

I also suspect the following may be helpful for the live preview, but haven't gotten it working.

sudo dnf install gstreamer1-plugins-bad-freeworld.x86_64 gstreamer1-svt-av1.x86_64 gstreamer1-plugins-bad-free-extras-1.22.5-1.fc38.x86_64

[magealexstra]

just fyi i'm running kubuntu 23.10 and to install i had to search and found it listed as libwebkit2gtk-4.0-37 in apt-cache.

installing allowed the app to launch.

sudo apt install libwebkit2gtk-4.0-37

Is there an AppImage which is not depended on a Debian/Ubuntu based system ?

[DupiDachs]

I am under Archlinux here and the package webkit2gtk4.0 is not provided here. But there is webkit2gtk4.1.

The workaround is to install version 4.1 via pacman -S webkit2gtk-4.1 and then create some symbolic links.

me@AsusLaptop: $ ldconfig -p | grep webkit
	libwebkit2gtk-4.1.so.0 (libc6,x86-64) => /usr/lib/libwebkit2gtk-4.1.so.0
	libwebkit2gtk-4.1.so (libc6,x86-64) => /usr/lib/libwebkit2gtk-4.1.so

and hence (you need to be in the folder of your AppImage),

me@AsusLaptop: $ ln -s /usr/lib/libwebkit2gtk-4.1.so.0 libwebkit2gtk-4.0.so.37

and also

me@AsusLaptop: $ ldconfig -p | grep libjava
	libjavascriptcoregtk-4.1.so.0 (libc6,x86-64) => /usr/lib/libjavascriptcoregtk-4.1.so.0
	libjavascriptcoregtk-4.1.so (libc6,x86-64) => /usr/lib/libjavascriptcoregtk-4.1.so

and hence (you need to be in the folder of your AppImage),

me@AsusLaptop: $ ln -s /usr/lib/libjavascriptcoregtk-4.1.so.0 libjavascriptcoregtk-4.0.so.18

Does the job for me. HF!

[czinehuba]

Slightly different directories, but it in Ubuntu 24.04 did the trick as well. cheers

sudo ln -s /lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0 /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 sudo ln -s /lib/x86_64-linux-gnu/libjavascriptcoregtk-4.1.so.0 /lib/x86_64-linux-gnu/libjavascriptcoregtk-4.0.so.18

That worked for me. I also installed the following packages (maybe not all of them needed): sudo apt-get install libwebkit2gtk-4.1-dev libwebkit2gtk-4.1-0 language-pack-en language-pack-en-base language-pack-gnome-en language-pack-gnome-en-base language-pack-kde-en

I did this and now I have the error:

"authentication failed due to unexpected error"

Kubuntu 24.04

[BadPixel89]

This is affecting Mint as well. I resolved by doing the following:

Create the links as outlined in a previous post: sudo ln -sf /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.1.so.0 /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 sudo ln -sf /usr/lib/x86_64-linux-gnu/libjavascriptcoregtk-4.1.so.0 /usr/lib/x86_64-linux-gnu/libjavascriptcoregtk-4.0.so.18

Move the appimage to a new folder, I chose: /home/BadPixel89/tools/OrcaSlicer/OrcaSlicer_Linux_V2.1.1.AppImage

you can run from terminal as others have: cd to the directory containing the app image and run the it from terminal with the following: WEBKIT_DISABLE_COMPOSITING_MODE=1 ./OrcaSlicer_Linux_V2.1.1.AppImageD

This allows you to run through the setup, choose a printer / filament profiles etc

To run from UI (Xfce Edition of Mint): edit: removed link to guide, this way works better

• Right click the start menu and click "Edit Applications"
• highlight the section you want the icon to appear under
• Click the blue plus in the top left to add a new launcher
• Name it something like OrcaSlicer, give it a description, and click the edit icon on the command field
• Click command, then click the browser icon and point it at your appimage
• Click environment variable and set
• • Variable to "WEBKIT_DISABLE_COMPOSITING_MODE"
• • Value to 1
• click apply
• I set working dir to the same folder containing the appimage as well
• click the blue save icon next to the plus, you can also click the cogs to test it without saving
• close the editor and save if prompted

Now you should be able to open start and type OrcaSlicer to open it like a normal app and use it.

Did not work for me on fedora 40, while it does start up after installing that package the welcome screen is blank. :(

[BadPixel89]

While it does start up after installing that package the welcome screen is blank. :(

Did you run it with the argument like this, I had the same result when not using the argument on Mint:

WEBKIT_DISABLE_COMPOSITING_MODE=1 ./OrcaSlicer_Linux_V2.1.1.AppImageD

[ExperimentalCyborg]

Oh crap i missed that detail. Thank you so much!

[xpcone]

WEBKIT_DISABLE_COMPOSITING_MODE=1 did not help, webkit 4.0 is too old

[ExperimentalCyborg]

Yeah i happily thanked badpixel after the gui showed up but the 3D render in the workspace still doesn't show up :joy: Until then i'll be using a laptop running mint 22 for slicing... :smiling_face_with_tear:

Same error here: /tmp/.mount_OrcaSlU9Wgv2/bin/orca-slicer: error while loading shared libraries: libwebkit2gtk-4.1.so.0: cannot open shared object file: No such file or directory

Worked for me in Linux Mint 22. Unfortunately, there is no "dark" mode theme on this version.,

This seems to be the oldest open issue regarding libwebkit2gtk-4.0.so.37 and the AppImage. Someone really should close the multitude of open duplicates: https://github.com/SoftFever/OrcaSlicer/issues?q=is%3Aissue%20state%3Aopen%20libwebkit2gtk-4.0.so.37

I accidentally posted in this closed issue: https://github.com/SoftFever/OrcaSlicer/issues/4616#issuecomment-2704402878

[timnolte]

It appears that this won't ever be fixed as 22.04 compatible AppImages have been dropped from the nightly builds. https://github.com/SoftFever/OrcaSlicer/issues/10111

Fair enough, this can be closed IMHO
