Comment 3 for bug 1068222

I get similar error on Ubuntu 16.10 upgrade:

sudo dpkg --configure -a
Setting up console-setup-linux (1.142ubuntu5) ...
update-alternatives: error: alternative path /etc/console-setup/vtrgb.vga doesn't exist
dpkg: error processing package console-setup-linux (--configure):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 console-setup-linux

Any workarounds? (The upgrade was otherwise OK)
