How to update Speedify on Linux
If you installed using the getspeedify script, then the Speedify repository has been added to your list of Package Sources. This means that when you use an "apt" based command to update the packages on your machine, Speedify will be automatically updated as well.
To update all the applications on your machine, including Speedify:
sudo apt update sudo apt upgrade
Alternatively to just update Speedify, if you installed the user interface run:
sudo apt update sudo apt upgrade speedifyui
If you are running without the user interface run:
sudo apt update sudo apt upgrade speedify
In any case, that should be it. "update" checks for new versions and the "upgrade" actually installs them. Speedify will automatically start the new version of the daemon once the update is complete.
