Describe the bug

Additional context

The problem seem related only to libsoup, but for completion I will add that as libjavascriptcoregtk-4.0 is not available anymore in Ubuntu 24.04, so I did install via apt libjavascriptcoregtk-4.1-dev and made some symbolic link changes... Other than that I just follow instructions as they are.

made some symbolic link changes

Yeah, and that's the issue probably. Either install webkitgtk 4.0 by enabling the 22.04 repos (https://github.com/tauri-apps/tauri/issues/9662) or just switch to tauri v2 to use webkitgtk 4.1 (npm create tauri-app@latest -- --rc). symlink experiments is in my eyes not a good approach and something we cannot offer help with.

[ildella]

Makes sense. The rc works out of the box indeed.

I would consider adding that optional command for the RC in the README.. that would have saved me 2 hours of work this morning.

[FabianLars]

Not worth it anymore tbh, we plan to release v2 as stable very soon. Btw, the --rc flag is documented in the v2 website. All other places like v1 docs and readmes tend to target the latest stable, but yeah, feedback is noted, thanks.
