Hi IvCHo,
Maybe it has nothing to do with your problem, but in [another topic][1] I explained the solution I found (from another website) for my bluetooth headphones issue:

sudo apt-get purge pulseaudio-module-bluetooth bluetooth bluez-* bluez
sudo apt-get install blueman bluez pulseaudio-module-bluetooth --install-suggests
pactl load-module module-bluetooth-discover

What is interesting is that for this to work, some bluetooth packages need to be purged on line 1 before being reinstalled on line 2.
I cannot say whether it would help in your case but maybe something to consider.

When I do the purge of bluez it gives me that it will delete ubuntu-mate-core and ubuntu-mate-desktop and if i do that my Mate Desktop will be deleted . When I do sudo apt-get install bluez-* it again gives me that ubuntu-mate-desktop and ubuntu-mate-core will be deleted .
pactl load-module module-bluetooth-discove gives the output 22 so this means it is started .

Hi!
Maybe you’ll find a hint

That is because you are running an unofficial release of Ubuntu MATE instead of those built and hosted by canonical

So if I wan’t to purge pidgin withought braking ubuntu-mate-core I have to do a clean install of Ubuntu Mate 15.04 ?

I understood that this behaviour is normal because these are meta packages (which happens when you want to remove an application like e.g. pluma or pidgin in your example) and that removing them will not break your distro. @Wimpy, can you please confirm?

In Ubuntu MATE 14.04 and 14.10 the unofficial build system uses meta-packages, which means if you try and remove a package within ubuntu-mate-desktop it will also remove the parent meta-package.

This limitation is removed in the official images from Ubuntu MATE 15.04 and onward.

The Bluetooth “fix” outlined above I’ve seen on various blogs, the package removal step is completely pointless.

So which is the proper fix, under Ubuntu MATE 15.04? The package manager shows I have bluez and blueman installed.

Solution checked . You should see it . Also Canonical ends support for 15.04 so you should upgrade to 15.10
