Mega is a secure cloud storage provider that offers at least 5GB of free encrypted storage. It also has apps for mobile and desktop and extensions for Firefox and Chromium. It is a great option to sync your important files between your devices, upload your photos from you phone or share files with your friends.
Installing Mega on Kubuntu 20.04 requires a couple of things. The first is an account with Mega. You can register with their service here. After registration you will want to go here to download the sync client. For Kubuntu 20.04 choose Ubuntu 20.04 and then click on the Linux button to download the file.
After downloading select the file causing it to open up in Discover. Once open there will be an install button on the top right that you can select and then enter your admin password to install the file.
After installation you can open Mega Sync in the Applications Menu by going to Applications/Internet. After it opens it will ask you for your user name and password and which folder you want to sync (although it has already created one called Mega).
