As you may know, Font Manager is an open-source application for managing fonts. Via a simple and intuitive interface, it allows the users to easily install new fonts or remove some of the installed fonts.
The latest version available is Font Manager 0.7.2 (an alpha version), which has been recently released, coming with a bunch of changes.
Despite the fact that the porting process has not been done completely, the application is already usable.
Up to date packages are available via some third party PPA, so installing the software on Ubuntu 15.10 Wily Werewolf, Ubuntu 15.04 Vivid Vervet, Ubuntu 14.04 Trusty Tahr and derivative systems like Linux Mint 17.2 Rafaela, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Deepin 2014, Peppermint 6, Peppermint 5, LXLE 14.04 and Linux Lite 2 systems is piece of cake.
All you need to do is add the PPA to your system, update the local repository index and install the font-manager package:
$ sudo add-apt-repository ppa:font-manager/staging
$ sudo apt-get update
$ sudo apt-get install font-manager
Optional, to remove font manager, do:
$ sudo apt-get remove font-manager
