It seems that 6.8.0-49 has not been installed previously or is not visible:
``` rc linux-image-6.8.0-47-generic 6.8.0-47.47 amd64 Signed kernel image generic rc linux-image-6.8.0-48-generic 6.8.0-48.48 amd64 Signed kernel image generic ii linux-image-6.8.0-50-generic 6.8.0-50.51 amd64 Signed kernel image generic ii linux-image-6.8.0-51-generic 6.8.0-51.52 amd64 Signed kernel image generic ii linux-image-generic 6.8.0-51.52 ``` However, I can confirm that this issue is not new. I experienced it around 8 months ago but never reported it. I wonder if the VPN connection might be causing something unusual (though that would potentially suggest a lower-level bug or some headless config issue which reflects on the bluetooth controller status). Will try without a VPN and see if the issue persists. In any case, the issue isn’t particularly strenuous. If it happens and I need Bluetooth again to connect my earbuds, I simply restart the laptop. It’s mildly annoying at worst. Have a great Christmas. Sent with Proton Mail secure email.
