pCloud - cloud storage from SwitzerlandInternet
It has all the standard functions of a cloud service such as file sharing and sync, selective sync, etc.
You can also listen music and create playlists right in your cloud, and for that a default music player is available. PCloud also has its own clients on different platforms, including Linux, of course.
Positive in pcloud:
10 GB of free space, expandable up to 20GB
Good working Linux client with GUI
Run latest version on Linux Mint:
Once registered, you will have access to as much as 10Gb of cloud storage, which you can extend by following a few more simple steps, and one of these steps is installing the client on Linux.
The Linux client is easy to use and works well in Ubuntu/Linux mint. Other systems have not tried.
2. app image file is available on the official website, which you can download after registration.
This is a very cool cloud service that provides not only free space, but also thinking about their customers, for example in this service, you can buy gigabytes of cloud space free of charge, that is, forever, well, tell me what else the client offers such services, usually offer to buy for a year or two.
