I was using Linux Mint and this was helpfull to install:
- Tor Borowser Bundle (Firefox browser made to work with Tor anonymity network)
- KeePass (Crossplatform software alllowing to store passwords and documents encrypted)
- ShadowSocks (Software that allows relaying internet traffic via remote proxy server in an encrypted way (both UDP and TCP))
- Truecrypt (crossplatform software allowing data encryption)

First add Ubuntu/Debian repositories:

sudo add-apt-repository ppa:webupd8team/tor-browser;sudo apt-add-repository ppa:jtaylor/keepass;sudo add-apt-repository ppa:hzwhuang/ss-qt5;sudo add-apt-repository ppa:stefansundin/truecrypt;
Update whole system and install Tor Browser Bundle + Keepass + ShadowSocks client + Truecrypt

sudo apt-get update -y;sudo apt-get install tor-browser keepass2 shadowsocks-qt5 truecrypt -y
All was then able to launch from the programs menu and all graphical interface.

Another usefull media player/streamer is mpv, it can stream youtube via command line:
sudo apt-get install mplayer mpv
mpv youtubeurlhere
