package brltty 5.3.1-1ubuntu3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

This bug might be similar to #1533040, but I should note that this is Ubuntu Mate running on a Raspberry Pi 2 (Arm v7), so I don't know if the other bug is on the same CPU architecture or not. Feel free to mark it as a duplicate if true. I was attempting to upgrade to Ubuntu 16.04, and it appears as if I ran into some dependency errors. I'll see if I can get them sorted out with aptitude in the mean time. System is still stable and boots up fine, but I would imagine this will affect new installs until the dependency error is resolved.

Here is the error output;

sudo aptitude upgrade

Setting up brltty (5.3.1-1ubuntu3) ...
update-initramfs: deferring update (trigger activated)
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults

That is where it stops. So far not even aptitude can fix this...
