Your Electurm is installed correctly what you need is to have the icon?
Yes, I'd like an icon but that's not the only issue. Electrum will not start by entering the "electrum" command in terminal. It seems like it should start by doing that if it's installed correctly.
Add ~/.local/bin to your PATH variable and it will:
export PATH="$PATH:/home/willy2streams/.local/bin"
Add the above line to your .bashrc file. Then close and open the terminal again and hopefully it'll work.
As I said before the installation instructions provided on the electrum download page are for an unprivileged user installation because they don't want you fetching modules from pip as root.
