Is this webpage address generator good for paper wallets or is it a phishing site?:
segwitaddress.org
I suppose that as I sweep old paper wallets I should do the world a favor and
start using SEGWIT paper wallets, is that correct? Or am I shooting myself
in the foot due to my noob-i-ness? Can someone point me to a good informative link?
THANK YOU!

Hello biddicoin,
This exact question drove me NUTTSSSS!
Here's how to remove the new Electrum 3.0.3 from Linux Mint:

sudo pip3 uninstall electrum

You will still have to manually delete the hidden folder. Press CTRL  and H to reveal .electrum in your home folder.
