USB bluetooth controller still appears even though hardware no longer present

Machine is running 16.04 LTS, current on updates.

I had an IOGear USB bluetooth adapter. Worked reasonably well. At one point I pulled it out to give to my son. Like a fool I just yoinked it out hot. Now I have a replacement, a IOGear GBU521 (which I think was the same as the original). I can’t get it to work, and I am suspecting it’s because the machine insists the previous adapter is still present.

Here is lsusb:

and hciconfig:

bluetoothctl list shows:

Controller 00:02:72:C8:AC:34 khym [default] 

The remove command in bluetoothctl does nothing (says “not available”).

I tried wiping the entries in /var/lib/bluetooth, but the entry for the phantom controller keeps returning. I also found and removed the firmware file /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd.

Boot messages include:

Sep 12 23:11:17 khym kernel: Bluetooth: hci0: BCM: chip id 63 Sep 12 23:11:17 khym kernel: Bluetooth: hci0: khym Sep 12 23:11:17 khym kernel: Bluetooth: hci0: BCM20702A1 (001.002.014) build 0000 Sep 12 23:11:17 khym kernel: bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-21e8.hcd failed with error -2 Sep 12 23:11:17 khym kernel: Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-21e8.hcd not found 

When I plug in the new adapter I get an appropriate entry in lsusb and hciconfig, but the gnome bluetooth panel doesn’t recognize it.

I’m thinking since the original controller worked without trouble, if I can get the machine to forget about it the new one should come up without further trouble.

A couple other notes: – This machine is somewhat old (core 2 duo) and currently has a dead CMOS battery so I get corrupted memory messages in my boot logs. Everything else works fine so I believe that isn’t relevant – Machine is using nvidia drivers for graphics (I know that was an issue years ago but is it still?)

I did a fair bit of searching, tried to infer where things are and how files should be based on posts of people getting their btusb to be recognized, but I haven’t come across anyone with the opposite problem!

Thanks in advance for any suggestions for further diagnosis!

“Grub loading… Welcome to grub” banner appears before grub bootloader loads

I have a dual boot system with kali and ubuntu. One week ago I did a system update with apt upgrade but interrupted it because kali did not respond if I moved the mouse. Now, when I start my laptop, there is the banner Grub loading... Welcome to grub!. The banner was not there before the update. Actually I did not experienced problems or damages so far but it is really annoying for me. Can I remove it or is it possible that the banner is sign for a possible damage?

Delated Facebook picture still appears on Google

I've delated a picture from my Facebook business page one month ago. It's still visible on Google. Google tells me that they can't do anything about it, and Facebook too (I have already contacted them both). What should I do?
NB: My business' name is "Scrivimi un biscotto" and the picture that I talk about shows "Parola di Biscotto" (which is the previous name of my business). Thank you in advance

On Boot up, Lightdm does not work and black screen appears

I updated ubuntu 16.04 LTS to ubuntu 18.04 LTS. On ubuntu 16.04 I was using gdm3, which got broken during upgrading because when I set gdm3 as default display manager in recovery mode through,

sudo dpkg-reconfigure gdm3 

it said “gdm3 is broken or not properly installed” so I set lightdm as default display manager.

Now, when I boot having lightdm, after the purple scree, the black screen appears and nothing happens. If I press Ctrl+Alt+F2 , it shows me the tty3 login screen. I login with my username and password. Sometimes, it accepts it and sometimes it doesn’t (which is an issue but not the major issue of this question).

After logging in, I can navigate my directories but I can’t open graphical window. I tried opening chromium using command “chromium-browser www.google.com” but it said something like “Graphical interface not permitted”.

How do I get my Graphical Interface back? Note that I can’t connect to wifi. I tried using

sudo ifconfig wlan0 up sudo iwconfig wlan0 essid name key s:password 

It gave error in setting password which was like “Invalid argument password, Set encode”. I tried giving hexadecimal password too without s:

sudo iwconfig wlan0 essid name key hexpassword 

Didn’t work either. How do I get my UI back? And can the internet be connected through ethernet?

The following error message appears when i run dpkg on linux ? What is the issus?

I used this command for removing the linux-image

sudo dpkg --remove --force-remove-reinstreq linux-image-4.4.0-116-generic 

But it shows the following error message

(Reading database ... 267739 files and directories currently installed.) Removing linux-image-4.4.0-116-generic (4.4.0-116.140) ...

What is the issue? I am not able to install new packages because of files like this. Please help.

17.10.1 repository Artful Aardvark appears to have been changed and is no longer located where it was

The 17.10.1 repository Artful Aardvark appears to have been changed and is no longer located where it was. None of the standard repository locations have 17.10 Artful located in them.

Right now, I’m not concerned about Opera web browser. I did find this though:

http://old-releases.ubuntu.com/releases/artful/

How do I add this to the repository lookup when I do an update? I know I have to go into the “Software & Updates” part of the Software package program, and add it under “Other Software”. But it tells me it has to be a complete APT line, where

“The APT line includes the type, location and components of a repository, for example ‘deb http://archive.ubuntu.com/ubuntu artful main’.”

I’m at a loss as to what to do next. Should I downgrade to 16.04 seeing that it’s still supported? The only reason I upgraded to 17.10 was because I was having audio issues using 16.04. The logical solution would be to upgrade to 18.04, except my hardware might not be able to handle it.

Any help is greatly appreciated. Thanks.
