If you run:

sudo apt-get install gksudo
gksudo cheese

Does it work OK?

Tried your suggestion with no result

[sudo] password for luis:

E: Unable to locate package gksudo
luis@luis-Ubuntu-16:~$ gksudo cheese

At this point Cheese open with same error

(cheese:3968): cheese-WARNING **: Failed to allocate a buffer: gstv4l2src.c(884): gst_v4l2src_create (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin18/GstV4l2Src:v4l2src1

luis@luis-Ubuntu-16:~$

OK, try:

sudo cheese

Any better?

Please ignore my last reply the Terminal output was taken from other Disk Drive with Ubuntu 16.04 32bit .

I apologize for the error but my main OS right now is the 32bit and wrongly use this Terminal
Now from 64bit OS Terminal output.

sudo apt-get install gksudo
luis@luis-H81M-DS2:~$ sudo apt-get install gsksudo

luis@luis-H81M-DS2:~$
I dont have another appliction open.

Are updates currently installing? If so then wait and let them finish. If you have a GUI package manager application open then close that and retry.

If not then run:
 sudo fuser -vki /var/lib/dpkg/lock
sudo dpkg --configure -a

Then try again. If asked, select yes to unlock the file

I had a new Ubuntu Update
Run this update then went to follow your initial suggestion.

Seagate 1T the reason was Skype now only works on 64bit and I needed it badly to contact family.
