[BUG] [Flatpak] URLs are not working

[andriej]

Title

URLs point to "about:blank" instead of proper url in browser

Platform

App - Linux

Server Installation Method

Docker

Version

2.2.1

Troubleshooting

• I have examined logs and tried to find the issue
• I have reviewed opened and closed issues
• I have tried restarting the application
• I have read Known Issues (Known Issues (Read Before Posting) #296)

The Problem

After URL is displayed in terminal and clicked in mouse, it point's browser URI to about:blank instead of opening proper url.
It works on web version properly, so has to be connected with managing links inside the app.

How to Reproduce

1. View URL
2. Click
3. (first time: choose program to open "about" with, choosing internet browser)
4. Browser opens about:blank

Additional Context

Thanks for reporting. The URL opening logic in the Electron app uses shell.openExternal() which relies on xdg-open under the hood. In Flatpak sandboxes this can fail silently if the desktop portal isn't properly available.

Could you provide some additional info to help us diagnose?

1. What desktop environment are you using? (GNOME, KDE, etc.)
2. Is xdg-desktop-portal running? (systemctl --user status xdg-desktop-portal)
3. Does running flatpak run --command=xdg-open com.karmaa.termix https://example.com open a browser?

This will help us determine whether it's a missing portal permission in our Flatpak manifest or a deeper sandbox issue.
