Without any cause that I can tell, all text has turned into boxes /rectangles everywhere in Ubuntu 16.04.

I am able to press ctrl-alt-F1 and go to shell, I have run :

apt-get update

And

apt-get upgrade

But this has not changed anything.

Any suggestions?

This can be the result of some invalid permissions settings on Font files. You need to set correct permissions for fonts.

To fix the permissions of all fonts ending with .ttf or .otf extension use these two commands.

find /usr/share/fonts -iname '*.ttf' -type f -exec sudo chmod -v 644 {} \;
find /usr/share/fonts -iname '*.otf' -type f -exec sudo chmod -v 644 {} \;

Then use this command to re-build font cache

sudo fc-cache -r -v

This should fix the problem.
