Public bug reported: Cannot enable WIFI & Bluethooth at fresh install of Kubuntu 24.04 LTS. «Hard blocks» or something else?
Update from the bug reporter, Bas Roufs, Tuesday 7 May 2024, at about 12.30 CEST, Mook, near Nijmegen, The Netherlands: For: Expert users and developers of Kubuntu and/or other flavours of *Ubuntu, who know about WIFI and Bluetooth - especially in connection with the package rfkill. Cc.: KDE Experts. Previous versions of this report I have submitted here: https://bugs.kde.org/show_bug.cgi?id=486368 KDE experts who have replied me there, emphasised that the issue needs to be resolved «downstream», in my case at the level of *Ubuntu. INTRODUCTION. ============ @ Kubuntu and other *Ubuntu expert users..... After checking the settings related to WIFI (and Bluetooth), I ended up filing a bug report at KDE: https://bugs.kde.org/show_bug.cgi?id=486368 According to the feedback I got from KDE experts after doing so, the problem is real. However, those experts say it cannot be solved at the side of KDE. It needs to be solved «downstream», so at the side of Kubuntu and other Ubuntu flavours in our case. That's why, i finally file this bug report. THE PROBLEM IN BRIEF. ==================== So far, I do not manage to get WIFI enabled by the useful steps at a fresh install of Kubuntu 24.04 LTS, at this laptop: Lenovo Thinkpad X230 i5, along with 4 GB RAM, 250 GB SSD. A quick internet search clarifies me that I am not the only one who deals with this problem. I do work now with wired internet. However, this wired connection does not help me so far to get the WIFI enabled. The same applies for Bluetooth. Neither GUI approaches, nor command line solves anything so far. Ticking the box for enabling WIFI is not possible. The same applies for Bluetooth. Check the screenshots I send along with this bug report. It's about the graphical check down under - fruitlessly trying to tick the box to enable WIFI or the one to enable Bluetooth. At each screenshot, you can see a red arrow pointing at a WIFI or Bluetooth check box that cannot be ticked. Here, I go through the screeenshots that I send along this bug report: 1. Mouse at WIFI connection corner right down under. I indicate the place to look at by means of a red arrow. 1a. Focus at mouse pointer at WIFI connection corner right down under. 2. Enabling WIFI not possible. The red arrow and the mouse pointer point at the box that cannot be ticked with a view to enabling WIFI. 2a. Detail - Enabling WIFI not possible. A more detailed look at the corner where the red arrow points at the box that cannot be ticked. 3. Bluetooth disbabled. The red arrow and the mouse pointer both point at the area where bluetooth should need to be enabled. 3a. Impossible to get Bluetooth enabled. After the click indicated by image 3, I end up here.... The button aimed at enabling Bluetooth cannot be toggled. This button is being indicated by the mouse pointer and the red arrow. A few terminal checks so far do not solve the problem. However, more info comes to the surface. Take a look at the next paragraph. COMMAND LINE OUTPUT REPORTS. ============================= Terminal checks derived from, amongst other pages: https://www.baeldung.com/linux/connect-network-cli https://www.baeldung.com/linux/disable-wireless-network bas@Camino:~$ iw dev phy#0 Interface wlp3s0 ifindex 3 wdev 0x1 addr 9c:4e:36:aa:5c:d0 type managed txpower 0.00 dBm multicast TXQ: qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets 0 0 0 0 0 0 0 0 0 bas@Camino:~$ sudo ip link set wlp3s0 up RTNETLINK answers: Operation not possible due to RF-kill bas@Camino:~$ bas@Camino:~$ nmcli radio wifi disabled bas@Camino:~$ nmcli radi wifi on bas@Camino:~$ sudo nmcli radio wifi on bas@Camino:~$ sudo ip link set wlp3s0 up RTNETLINK answers: Operation not possible due to RF-kill bas@Camino:~$ bas@Camino:~$ rfkill list 0: tpacpi_bluetooth_sw: Bluetooth Soft blocked: yes Hard blocked: yes 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes bas@Camino:~$ STEPS TO REPRODUCE ================= 1. Check my screeenshots attached to this bug report. See also above, «THE PROBLEM IN BRIEF». 2. Command line checks summarised here - see here above, «COMMAND LINE OUTPUT REPORTS.», What I expected to happen. ========================= Enabling WIFI should need to be possible via either command line, the graphical approach or both of them. In early April 2024, only some weeks ago, I have fresh-installed Kubuntu 22.04.4 LTS at exactly the same laptop, with the same SSD, the same hardware specs and BIOS settings. At that configuration, WIFI worked out of the box, simply correctly. Bluethooth worked also - however, with hiccups and interruptions. I expected similar results after fresh-installing Kubuntu 24.04 LTS. More info about my laptop: see here below, «Software and hardware system info». what happened instead. ======================== So far, it has not yet been possible to enable WIFI and Bluethooth. At the GUI screenshots I send along with this report, you can see the check boxes that CANNOT be ticked with a view to enabling WIFI and Bluethooth. The terminal checks summarised here above, produce some useful info. However, they do so far not bring any solution that helps to enable WIFI and BLuetooth.

HARD BLOCKS AND/OR SOMETHING ELSE? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ On Wednesday 1 May 2024, a comment came in about this passage in my bug report at KDE, https://bugs.kde.org/show_bug.cgi?id=486368 > bas@Camino:~$ rfkill list > 0: tpacpi_bluetooth_sw: Bluetooth > Soft blocked: yes > Hard blocked: yes > 1: phy0: Wireless LAN > Soft blocked: no > Hard blocked: yes This is the comment I point at: «(...) If it is hardblocked, it cannot be enabled in software. E.g., see https://askubuntu.com/questions/98702/how-to-unblock-something-listed- in-rfkill Unfortunately this seems like a downstream configuration issue and I would suggest asking for help on the distribution forums. (...)» More about Bluetooth. --------------------- Here below, I carry out some checks recommended in this article: https://community.spiceworks.com/t/how-to-verify-bluetooth-using-linux- command/961891 bas@Camino:~$ bluetoothctl -v bluetoothctl: 5.72 bas@Camino:~$ No error report so far - there is apparently SOME bluetooth in the system. Now, I check whether bluetooth is running or not..... bas@Camino:~$ systemctl status bluetooth ● bluetooth.service - Bluetooth service Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: enabled) Active: active (running) since Fri 2024-05-03 14:49:51 CEST; 5h 40min ago Docs: man:bluetoothd(8) Main PID: 1931 (bluetoothd) Status: "Running" Tasks: 1 (limit: 4220) Memory: 552.0K (peak: 2.9M swap: 412.0K swap peak: 412.0K) CPU: 98ms CGroup: /system.slice/bluetooth.service └─1931 /usr/libexec/bluetooth/bluetoothd mei 03 14:49:51 Camino bluetoothd[1931]: Starting SDP server mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support csip plugin mei 03 14:49:51 Camino bluetoothd[1931]: profiles/audio/micp.c:micp_init() D-Bus experimental not enabled mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support micp plugin mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support vcp plugin mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support mcp plugin mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support bass plugin mei 03 14:49:51 Camino bluetoothd[1931]: src/plugin.c:plugin_init() System does not support bap plugin mei 03 14:49:51 Camino bluetoothd[1931]: Bluetooth management interface 1.22 initialized mei 03 14:49:51 Camino bluetoothd[1931]: src/profile.c:register_profile() :1.53 tried to register 0000111e-00> lines 1-22/22 (END) Apparently, it is running, however, with some complications. How to fix them? Can anybody help with this? Now, I try this..... bas@Camino:~$ sudo systemctl start bluetooth [sudo] password for bas: bas@Camino:~$ No error report here. Now, I try again this command: systemctl status bluetooth The result I get is exactly as above. Now, I gonna check whether or not all required packages have been installed: sudo apt list --installed | grep blue bas@Camino:~$ sudo apt list --installed | grep blue [sudo] password for bas: WARNING: apt does not have a stable CLI interface. Use with caution in scripts. bluedevil/noble,now 4:5.27.11-0ubuntu2 amd64 [installed,automatic] bluez-cups/noble,now 5.72-0ubuntu5 amd64 [installed,automatic] bluez-obexd/noble,now 5.72-0ubuntu5 amd64 [installed,automatic] bluez/noble,now 5.72-0ubuntu5 amd64 [installed,automatic] libbluetooth3/noble,now 5.72-0ubuntu5 amd64 [installed,automatic] libkf5bluezqt-data/noble,noble,now 5.115.0-0ubuntu6 all [installed,automatic] libkf5bluezqt6/noble,now 5.115.0-0ubuntu6 amd64 [installed,automatic] libspa-0.2-bluetooth/noble,now 1.0.5-1 amd64 [installed,automatic] qml-module-org-kde-bluezqt/noble,now 5.115.0-0ubuntu6 amd64 [installed,automatic] Apparently, everything needed has been installed. Now, I look at the «bluetooth adapter» and connectivity issues. sudo hciconfig hci0 reset bas@Camino:~$ sudo hciconfig hci0 reset Can't get device info: No such device This is weird....This points at some hardare issue? On the other hand... at exactly the same laptop with the same specs, I DID work with Bluetooth. However, it was not reliable. There were hiccups. By toggling FN + F5, I tried to get Bluetooth and or WIFI working.... But the test «sudo hciconfig hci0 reset» delivers the same non-result. Any conflicting Bluetooth related services running? I try this command.... sudo systemctl list-units | grep -i bluetooth bas@Camino:~$ sudo systemctl list-units | grep -i bluetooth bluetooth.service loaded active running Bluetooth service bas@Camino:~$ Apparently, there is one process running. But I still cannot «enable» Bluetooth. No clue what to do next to get Bluetooth running. SUMMARY AND CONCLUSION: HARDWARE ISSUES OR SOMETHING ELSE? ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ For both WIFI and Bluetooth, command output results shared in this report seemingly point at hardware issues, hard blocs, etc.On the other hand, at exactly the same laptop along with the same BIOS settings, I WAS able to work with those techniques along with Kubuntu 22.04.4 LTS - WIFI out of the box, BLuetooth with some hiccups and interruptions. Terminal output reports shared here above, indeed do point at «hard blocks» for both WIFI and Bluetooth. Also a few Kubuntu expert users I spoke with so far, think in the same direction, which I understand. On the other hand - Only a few weeks ago, I have been working with Kubuntu 22.04.4 LTS at exactly the same laptop with the same hardware and the same BIOS settings. Then, WIFI worked out of the box and Bluetooth with some hiccups and interruptions. BIOS settings at my Lenovo X230: NO «security» enabled. No BIOS password! Provisional conclusion: I am really not sure whether «hard blocks» or any other hardware issues are the core issue.
