The best way is to run the installation script described on the official website every time Calibre notifies you of an update:
Code:
sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin
. Use this command in the terminal, and the next time you open the terminal, you won't need to copy it again. Just move the arrow up, and the commands you've used will appear.
If you use this method, you'll have Calibre updated on the same day as the notification. The formats you mentioned often take more than a week to update.
