Hi Walter! Thank you for your support. Would you please send me a link with some guide to install a desktop environment like the ones you suggested? I looked for it, and I found so many things even not very updated. It may seem very basic, but I'm new to Linux. Thank you again, regards!
(ps: one thing about the CLI, I tried to use " dropbox lansync [y/n] " -so with No- to stop synchro, but it's not clear what it does, the CLI doesn't say if it's effective or not, maybe I should use stop and restart dropbox daemon? "dropbox start [-i]" and "dropbox stop")
