I just had a .ttf font I wanted to install to use in conky, but by double-clicking and executing it, the installer (font-viewer) failed. I received the error message "Install Failed". No clue why this has happened as I have previously installed fonts this way.
|"Install Failed" message when trying to install font|
I knew about gnome-font-viewer that I could get from the Software Centre, but I didn't feel like installing another software just to get a new font. There has to be another way.
SolutionThe solution, turned out, was quite simple. Copy the .ttf file to ~/.fonts/ and you are good to go. No logout or restart is needed, nothing.
So from the terminal,
cp /route/to/font.ttf ~/.fonts/
After this when starting a document editing software, e.g. AbiWord, the new fonts will be available.
