Bug ID: 513461
Summary: kdeconnectd logspam: "Cannot find Bluez 5 adapter for
device search false"
Classification: Applications
Product: kdeconnect
Version First 25.12.0
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: desktop-application
Assignee: [email protected]

Target Milestone: ---
SUMMARY
Every 30s, kdeconnectd logs this to the system log, from `journalctl -b`:
Dec 17 00:20:03 hostname kdeconnectd[2707]: Cannot find Bluez 5 adapter for
device search false
Dec 17 00:20:33 hostname kdeconnectd[2707]: Cannot find Bluez 5 adapter for
device search false
Dec 17 00:21:03 hostname kdeconnectd[2707]: Cannot find Bluez 5 adapter for
device search false
Dec 17 00:21:33 hostname kdeconnectd[2707]: Cannot find Bluez 5 adapter for
device search false
This started happening after Fedora 43 upgraded to KDE Gear 25.12.0 + KDE
Plasma 6.5.4 + KDE Frameworks 6.21 in
https://bodhi.fedoraproject.org/updates/FEDORA-2025-e2d6cf1cf4. The system is a
desktop without any Bluetooth adapters.
These are the log entries for kdeconnectd leading up to the logspam:
Dec 16 23:54:03 hostname kdeconnectd[2707]: Cannot find a compatible running
Bluez. Please check the Bluez installation. QtBluetooth requires at least BlueZ
version 5.
Dec 16 23:54:03 hostname kdeconnectd[2707]: No local bluetooth adapter found
Dec 16 23:54:03 hostname kdeconnectd[2707]: No Primary Battery detected on this
system. This may be a bug.
Dec 16 23:54:03 hostname kdeconnectd[2707]: Total quantity of batteries found:
0
Dec 16 23:54:03 hostname kdeconnectd[2707]: Primary Battery seems to have been
removed. Suspending packets until it is reconnected.
Dec 16 23:54:03 hostname kdeconnectd[2707]: No object for name
"alsa_output.pci-0000_09_00.6.analog-stereo.monitor"
Dec 16 23:54:04 hostname kdeconnectd[2863]: QThreadStorage: entry 2 destroyed
before end of thread 0x55c8852620b0
Dec 16 23:54:04 hostname kdeconnectd[2863]: QThreadStorage: entry 1 destroyed
before end of thread 0x55c8852620b0
Dec 16 23:54:04 hostname kdeconnectd[2707]: Failed to register with host portal
QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID:
Connection already associated with an application ID")
Dec 16 23:54:33 hostname kdeconnectd[2707]: Missing CAP_NET_ADMIN permission.
Cannot determine whether a found address is of random or public type.
Dec 16 23:54:33 hostname kdeconnectd[2707]: Cannot find Bluez 5 adapter for
device search false
The first line on "Cannot find a compatible running Bluez" seems to have always
been there, the relevant packages are installed:
bluedevil-6.5.4-1.fc43.x86_64
bluez-5.85-1.fc43.x86_64
bluez-libs-5.85-1.fc43.x86_64
bluez-obexd-5.85-1.fc43.x86_64
bluez-cups-5.85-1.fc43.x86_64
bluez-libs-5.85-1.fc43.i686
kf5-bluez-qt-5.116.0-4.fc43.x86_64
kf6-bluez-qt-6.21.0-1.fc43.x86_64
STEPS TO REPRODUCE
1. Log in to a KDE session with kdeconnectd installed.
2. Run `journalctl -b`.
3.
OBSERVED RESULT
Logspam every 30s as shown above.
EXPECTED RESULT
No logspam.
SOFTWARE/OS VERSIONS
Linux: Fedora 43
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
ADDITIONAL INFORMATION
Workaround is to disable the Bluetooth backend in kdeconnectd then the logspam
stops but this has to be done for every user.
A similar bug was raised in https://bugs.kde.org/show_bug.cgi?id=417421 but
that log entry ends in "device search true" instead.
