For those who want to install the latest Remmina 1.2.0, the default GTK+ remote desktop client, a core developer has made the new Remmina Snap app for Ubuntu 16.04, Ubuntu 16.10, and higher.
Remmina is a free and open-source remote desktop client written in GTK+, aiming to be useful for system administrators and travellers, who need to work with lots of remote computers in front of either large monitors or tiny netbooks. Remmina supports multiple network protocols in an integrated and consistant user interface.
Currently RDP, VNC, SPICE, NX, XDMCP and SSH are supported.
sudo apt install snapd
So you can easily launch Ubuntu Software App and search for Remmina. Besides the original installed version, you’ll see a new Remmina package from Ubuntu Snappy Store.
Click install it and you’re done. For command line, you can use the following command to install the client:
sudo snap install remmina
NOTE: The Snap app in Ubuntu Desktop is currently not perfect, it may not respect your GTK and/or icon theme.
Don’t like the Snap app? For Ubuntu 14.04, Ubuntu 16.04, Ubuntu 16.10, and derivatives, there’s also Remmina Next PPA that contains the latest DEB packages.
1. Remove the snap app via Ubuntu Software, then open terminal (Ctrl+Alt+T) and run command to add the PPA:
sudo add-apt-repository ppa:remmina-ppa-team/remmina-next
Type in password (no visual feedback) when it prompts and hit Enter.
2. Then you can upgrade the original version of the software to the latest via Software Updater utility.[h4]Uninstall:[/h4]
To get rid of the PPA repository and restore to the shipped version of Remmina in Ubuntu, use ppa-purge tool via command:
sudo apt install ppa-purge && sudo ppa-purge ppa:remmina-ppa-team/remmina-next
