package dictionaries-common 1.20.2 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 255

[DonQuichote]

In the middle of a release upgrade, I am suddenly presented with a crash report. I am in the middle of it, so I do not know wether this will leave me with an incomplete system (again, after the bug about my processor that DOES support pae, but is not recognized) or not.

I did not do anything special, other than:

sudo do-release-upgrade -d

I added the -d option because even upgrading from a less-than a year old Xubuntu version (13.04 to 13.10, current) no longer works normally.
Output of lsb_release -rd:
Description: Ubuntu 13.10
Release: 13.10
But notice that I am in the middle of upgrading to that version.
I would off course expect the release upgrade to succeed, not a crash report.

For the record, I am upgrading the machine over an SSH connection with X support enabled.

I recognise the bug as a duplicate, but for the record: the bug did leave me with a complete system. I ran
sudo apt-get update
and
sudo apt-get upgrade
and there was only an (unrelated I think) issue with MariaDB from another repository.
