Arch Linux User Repository

Issue Fixed - 2026-04-16

Problem: The download URL was returning HTTP 403 Forbidden errors. The previous URL included a signature hash (e.g., x64signed_ffutrq3xq6f5.deb) that was time-limited.

Solution: Removed the signature hash from the URL. The URL without the signature (x64signed.deb) is a stable, permanent endpoint that works correctly.

Details:

• The unsigned URL (x64signed.deb) returns the exact same file with the same SHA512 checksum
• No changes to package contents or dependencies
• pkgrel bumped to 2 to signal the fix

Why this works: The signed URLs appear to be pre-authenticated CloudFront/S3 URLs with short expiration times. The unsigned URL appears to be a permanent, publicly accessible endpoint.

Go to https://www.webull.com/trading-platforms/desktop-app, click on the linux(Ubuntu) link to get and confirm a working link(seem to change often) to the required .deb file. Go to your paru cache folder \ directory for webull ~/.cache/paru/clone/webull-desktop/. edit & save the URL link in PKGBUILD and SRCINFO to any of the working links (this one worked for me as of today "https://u1sweb.webullfintech.com/us/Webull%20Desktop_9.3.0_9100000072_global_x64signed_fhsw97jm1tz5.deb" ). Open a terminal window from this directory and enter command "makepkg -si". Refer to the following links on using makepkg https://app.studyraid.com/en/read/32178/1407717/generating-the-package-with-makepkg , https://wiki.archlinux.org/title/Makepkg , https://pacman.archlinux.page/makepkg.8.html .

The link to the .deb file is inaccessible. It's giving me errors using paru and yay. Could anyone familiar with resolving these kinds of issues help with this?

drpr15 Also getting a 403 forbidden on the download. But switching to this url worked: https://u1sweb.webullfintech.com/us/Webull%20Desktop_9.3.0_9100000072_global_x64signed_fg9a8yykmo75.deb

Getting error 403 (Forbidden) when it tries to download the .deb. When I manually download the file from their site, I see a different signed_blah string. Perhaps there's a different link that doesn't include this bit that would be more reliable? (Note: the file I got manually has the same checksum that the pkgbuild calls out)

Updated to 9.3.0 (2026-03-13)

Thank you to postadelmaga for the PKGBUILD fix!

Changes:

• Updated to version 9.3.0

• Added dependencies: qtav (AUR) and libcurl-gnutls

• Removed conflicting bundled libraries: libgnutls.so and libnghttp2.so

To install:

paru -S webull-desktop

Note: Run with LD_LIBRARY_PATH=/opt/WebullDesktop or use the desktop file which handles this automatically.

cacoro2 Did you ever find a solution to the error when clicking on news links in Webull?

kde-open: symbol lookup error: /usr/lib/libproxy/libpxbackend-1.0.so: undefined symbol: g_strv_builder_unref

I'm running on Manjaro fully updated.

please update to new version 9.3.0: https://u1sweb.webullfintech.com/us/Webull%20Desktop_9.3.0_9100000072_global_x64signed_fbf1sou1qznl.deb

Here a PKGBUILD that fix all issues for the new version: https://pastebin.com/FjYT1sL9

ISSUES:

• /usr/share/licenses/$pkgname/LICENSE.txt is not present anymore in the new deb package

• New dependency qtav -> After installing ERROR: WebullDesktop: error while loading shared libraries: libQtAV.so.1: cannot open shared object file: No such file or directory

• New dependency libcurl-gnutls (removed the one present in the package as it create issues ) -> ERROR /opt/WebullDesktop/WebullDesktop: /opt/WebullDesktop/libgnutls.so.30: version 'GNUTLS_3_6_13' not found (required by /usr/lib/libcurl-gnutls.so.4)

• the lib libnghttp2.so included in the package create an error so has been removed after the installation

I'm on Wayland and when I try clicking links, the app just freezes. I'm not seeing anything out of the ordinary in the logs. Anyone have a solution?

EDIT: I've spun up an Ubuntu VM, installed the native deb package and had the same issue there. I guess it's just a bug.

Maybe I'm missing a library. I get the following console message when I double click a link:
