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

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.

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

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

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

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!

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:
