Can't uninstall Electrum

[Socman]

Installed Electrum to Linux Mint in terminal using these commands (from Electrum Download page):

Install dependencies:
sudo apt-get install python-qt4 python-pip
Install Electrum:
sudo pip install https://download.electrum.org/2.6.4/Electrum-2.6.4.tar.gz

It worked, and Electrum appeared in my main menu, under the "Office" category.   Ran it, set up my passwords, etc.   Electrum works and when I start it, I get my "Electrum 2.6.4 default wallet".   Received some bitcoin sent to me.  So all appears to work.  

My problem - when I go to my menu and right click Electrum to "uninstall", the uninstall fails and I get this error messege:

"Unable to locate package electrum"

Also tried from terminal, same fail:

"sudo apt-get remove electrum
Reading package lists... Done
Building dependency tree      
Reading state information... Done
E: Unable to locate package electrum"

Thanks very much.  


******************

Addendum:


Tried again and now when I try to uninstall by right-clicking Electrum in Office Menu, I get:

"Unable to locate package dpkg-query"

I clicked "remove", tried again, same answer.   Tried terminal again and still get same fail as above:

"sudo apt-get remove electrum
Reading package lists... Done
Building dependency tree      
Reading state information... Done
E: Unable to locate package electrum"

Your help will be GREATLY appreciated.  I really need to uninstall Electrum...

Additional stuff:

1.  There is an ".electrum" folder in home/computer/.electrum

2.  I used Synaptic Package Manager  to reinstall "dpkg" successfully.   Electrum does not appear in Synaptic

2.  There is a "dpkg-query" in usr/bin (as well as "dpkg" and a few other dpkg related files)

3.  I can install and uninstall packages from the Mint 13 Software Manager.   All programs including Electrum seem to run just fine.



In sum, although I really want to uninstall Electrum, it seems this can't be accomplished with this "outside" package, which doesn't appear in either the Mint 13 or Ubuntu Software Managers.    I may have to just live with this hitchhiking parasite - doesn't take up much memory, and doesn't seem to hurt anything.

But I'd sure like to get it off my laptop - thanks again for any advice...

Well delayed bump ...  can anyone please help?   Thanks...

apt is for downloading stuff from your distro's repos i.e. ubuntu's repos. you installed electrum manually without using your distro's repos. To remove it use:

sudo pip uninstall electrum


You can remove the electrum dependencies via apt because that's what you used to install them:

sudo apt-get remove python-qt4 python-pip

Even after you do all of the above your electrum wallet will remain in ~/.electrum. Because deleting a bitcoin wallet can lead to monetary loss electrum does not remove them when you remove it. So you can delete that folder manually but be sure to write down your seed words first (13 random english words).
