Thank you everyone for you responses.

First, a clarification:

I intend to stay on jessie version, and do not want to mix different releases.
Therefore I don't intend on adding the 'ascii' sources to my sources list.

I don't even need that much to upgrade, I was just doing my usual weekly routine of 'apt update' and 'apt upgrade' when I noticed this error.

Currently I don't see the new version of the package in question.

My sources are the original ones.

#cat /etc/apt/sources.list |grep 'deb http'
deb http://auto.mirror.devuan.org/merged/ jessie contrib non-free main 
deb http://auto.mirror.devuan.org/merged/ jessie-security main contrib non-free 
deb http://auto.mirror.devuan.org/merged/ jessie-updates main contrib non-free 

However golinux says that 'auto.mirror' is now deprecated.

So what exactly I should replace it with?

This page
https://devuan.org/os/

shows the same urls that I do have.

Do I have to add some kind of 'experimental/proposed' repo and pull the package from there?

I don't normally like to fiddle with 'experimental' branches, and prefer to use stable/oldstable editions
to save myself the trouble of debugging software which is too raw.

However since I started this discussion, I am willing to help ensure that everything works OK now, but you have to tell me
exactly what I should add to my sources.list to see the new version.

Regarding bug report: I sent an email to 'submit (at) bugs (dot) devuan (dot) org' on July 30 2018 from the same email I used
to register on the forum.

Regarding blocked IP: I've installed wireshark and it is running in the background as I type this message. I don't see any head requests
being made right now.

Quick report on what I was doing when banned: I wrote one reply, than wrote another reply, clicked 'preview message', than I was faced with
a message saying my IP is blocked. Using palemoon 27.8.1.

So this message is being written in external text editor, just in case.

Once again, thanks everyone for your time.
