I want to completely remove libfreenect from my Ubuntu 16.04 laptop. Right now, when I run locate libfreenect I get this:

EDIT 1

Trying to uninstall the package libfreenect-dev:

~$ sudo apt-get remove libfreenect-dev

~$ 

It's in spanish and it says that there is no package with this name installed.

EDIT 2

After running updatedb I get:

~$ locate libfreenect
/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so
/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so.0
/var/cache/apt/archives/libfreenect-bin_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/libfreenect-dev_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/libfreenect-doc_1%3a0.5.3-1_all.deb
/var/cache/apt/archives/libfreenect0.5_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/ros-kinetic-libfreenect_0.5.1-0xenial-20190607-170601-0800_amd64.deb

EDIT 3

After running apt-get clean and sudo updatedb again, I just get:

~$ locate libfreenect
/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so
/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so.0

I think that I've installed it by source, but I have removed the source file. How can I uninstall them?

You need to do

sudo updatedb

to update changes to the filesystem. After that removed items will disappear from the results shown.

edit:

These 4 are the installer files Ubuntu keeps on your system and you can remove these with the rm command.

/var/cache/apt/archives/libfreenect-bin_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/libfreenect-dev_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/libfreenect-doc_1%3a0.5.3-1_all.deb
/var/cache/apt/archives/libfreenect0.5_1%3a0.5.3-1_amd64.deb
/var/cache/apt/archives/ros-kinetic-libfreenect_0.5.1-0xenial-20190607-170601-0800_amd64.deb

So

rm /var/cache/apt/archives/*libfreenect*amd64.deb

Do a sudo updatebd after removing to remove them from the results.

There are part of OpenNI2. Do you still have that installed?

/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so
/usr/lib/OpenNI2/Drivers/libfreenect2-openni2.so.0

If you do: uninstall that with the method corresponding to what you installed it with (apt -> apt remove, from source there might be an uninstaller).
