webkitgtk-6 is broken

[Samueru-sama]

https://github.com/Samueru-sama/NewsFlash-AppImage/releases/tag/4.1.4-1%402025-11-09_1762691167

Steps to reproduce the issue:

• Extract the AppImage

• Run SHARUN_DIR="$PWD"/AppDir ./AppDir/shared/lib/webkitgtk-6.0/MiniBrowser

This causes the following error:

Unable to spawn a new child process: Failed to spawn child process “/tmp/N3G/webkitgtk-6.0/WebKitNetworkProcess” (No such file or directory)

If I copy ./AppDir/shared to ./AppDir/shared/lib/webkitgtk-6.0 it works!

Replacing the sharun hardlinks with symlinks causes this error:

bwrap: execvp /tmp/N3G/webkitgtk-6.0/WebKitWebProcess

So the problem seems to be that we have a double sandbox in here??? Whatever is calling bwrap does not have access to SHARUN_DIR.

Okay the problem does not look like a double sandbox, since I made a bwrap script in the AppImage to check if I had to full access to the AppDir and I do.

The solution should be that sharun needs to walk back every single parent directory until it finds the shared/bin directory it needs.

This is not weird and in fact servo browser does this with its resources directory xd

Yeah this is very fucked

This only happens in fedora btw

Noticed the latest commits added some of the sharun dir checks: Updated artifact with latest sharun

right now this is working because I added a workaround that involves making a bwrap wrapper script that all it does is bypass bwrap completely to work without sandbox (bad).

To test with bwrap you have to remove that script and place a symlink to the real bwrap since webkit2gtk also has the path hardcoded to /usr/bin/bwrap and this had to be patched...

Failed to check ELF class: /tmp/Xti/webkitgtk-6.0/shared/bin/WebKitWebProcess: No such file or directory (os error 2)

sharun is still trying to find a shared/bin dir where the WebKitWebProcess hardlink is located.
