Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed"[...]

I consistently get the following error in my journalctl output. I am looking at a batch that occurred about every minute for ~8 minutes.

baloo_file_extractor[####]: Failed to register with host portal QDBusError("org.freedesktop.portalError.Failed", "Could not register app ID: App info not found for 'org.kde.baloo'")

The error only ever references baloo, and is quite persistent. It also tends to coincide with UFW BLOCK messages, however, I can’t confirm if they are intertwined.

Is this even an issue? Is there a safe way to prevent this error from printing? I’m trying to troubleshoot some other issues and in the meantime reduce log spam to make that easier.

I have the same issue. Except I don’t see any UFW BLOCK Mesages.

I was encountering the same issue. I pieced together a solution based on a Manjaro forum post, which I am unable to link to for some reason. My solution was to create a file called /usr/share/applications/org.kde.baloo.desktop, with the following contents:

[Desktop Entry]
Name=KDE Baloo (compat)
Exec=/usr/bin/balooshow6 %u
Type=Application
NoDisplay=true
X-Desktop-File-Install-Version=5.0

I don’t know if it’s exactly right, but at least the warning I was getting has stopped showing up in the logs.

Note that I’m on CachyOS. YMMV.

Do you know what this does exactly? I don’t necessarily want to blindly apply a fix

Same here. CachyOS (feb 2026). I also found the same post in that Manjaro forum (missing root *.desktop file in /usr/share/applications/ ) and was short of the Exec line, which I took for your suggestion after verifying it did connect to Baloo.

Fingers crossed the warning is gone : I’ll come back to report after a few reboots and sleeps (my issue seem to pop up after resuming the computer from sleep).
