electrum update 4.4.6

I have been trying to update to the latest electrum version 4.4.6 as the wallet tells me to update.
I removed the app and tried to follow the instructions for installation from phyton sources but when i put this command:

wget htts://download.electrum.org/4.4.6/Electrum-4.4.6.tar.gz

the terminal says it’s not correct command.
I am very new and hope in your help
Thank You
