package brltty 5.3.1-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 6

[James Henstridge]

The package install failed when trying to restart the brltty service. It suggested checking the status using systemctl, which showed the following errors:

Jan 12 11:32:13 scruffy systemd[1]: [/lib/systemd/system/brltty.service:16] Unbalanced quoting, ignoring: "/bin/sh -c "grep -sq '^ *RUN_BRLTTY=no' /etc/default/brltty || exec /sbin/brltty --no-daemon"
Jan 12 11:32:13 scruffy systemd[1]: brltty.service: Service lacks both ExecStart= and ExecStop= setting. Refusing.

Editing line 16 of /lib/systemd/system/brltty.service to add the missing quote at the end of the line allowed the install to complete using "apt-get install -f".
