Removing a program in Ubuntu--unable to find package name

Question

I want to remove program "fio" from my Ubuntu. First, tried

apt-get remove fio

but it did not work. Then I tried to find its package name by

whereis fio 
dpkg-query -S /usr/local/bin/fio

but dpkg-query says "no path found matching pattern /usr/local/bin/fio". Any suggestion would be appreciated.

How did you install the program? Files from Ubuntu packages (.deb files) are usually not installed in /usr/local/. — Florian Diesch, Jan 15, 2015 at 16:45
I see it as an un-installed package. I am pretty sure now that I have installed from source code using ./configure && make && make install . — user3684042, Jan 15, 2015 at 21:56
Did you try to run make uninstall from the same directory as make install? — David Foerster, Mar 10, 2015 at 0:48

Now the problem is moot, but for the future:

Always use the same removal method as the installation method.

Therefore, use the following priority in installing software

Install/remove from the standard Ubuntu repositories using the GUI of the Ubuntu Software center.
Use the TUI of aptitude
apt-get install szPackageName to install and apt-get purge szPackageName to completely remove and apt-get remove szPackageName to remove the application, but not its configuration files.
Download and install a .deb file: use dpgk --install szPackageName and dpgk --purge szPackageName and dpgk --remove szPackageName as above.
So if you do download and build from source, use CheckInstall to be able to remove more easily in the future.
