[tor-relays] Help! TOR Relat dead after upgrading Ubuntu to 18.04

First off, will outline that I am very much a newbie, but was able to get a relay up and running on a Ubuntu machine. It was running fine for maybe 12 months (MelbTorBox), with a few resets and software updates along the way.

Just doing my bit to help the network.

Anyway, after the Ubuntu upgrade, I had to re-install TOR and I believed I did it basically the same way.

Unfortunately, that appears not to be the case.

I've posted the error messages on the Ubuntu forum hoping to get assistance, but no joy:

https://askubuntu.com/questions/1070469/18-04-tor-relay-error-could-not-bind-to-0-0-0-09050-address-already-in-use-i

I'm now coming to the experts to see if I can resurrect relay before I pull the pin on the idea.

I have BASIC Unix knowledge (I can type commands and that's about it). I think I might have a couple of copies installed in different places and I know I have the TOR browser installed (it works fine).

When I type 'nyx' it replies with:

Unable to connect to tor. Maybe it's running without a ControlPort?

So I type 'tor' and get

I 'think' my original torrc file may have somehow survived the Ubuntu upgrade, but I don't know how as I did a wipe and re-install of Ubuntu. But when I edited it, there were my contact details sitting there.

Very appreciative of any help!

Thanks

Ben.
