Hi everybody,

After nearly a couple of decades using C# in industry, it looks like I'm coming back to Mercury!

I'm trying to install Mercury under WSL on my home Windows box and I'm getting nowhere.  (Please forgive me if I come across a touch Forest Gump: even back in the day I only had half a clue about Linux admin.)  If anyone can offer advice, I'd be most grateful.  I've installed Arch Linux under WSL and I'm trying to install Mercury using the instructions at Mercury packages for .deb based systems<https://dl.mercurylang.org/deb/>

Now Arch, it seems, uses something called 'pacman' to install things, whereas the instructions refer to 'apt'.  Okay, so


  *
I install 'apt', edit /etc/apt/sources.list.d/mercury.list to include

deb http://dl.mercurylang.org/deb/ DISTRO main
deb-src http://dl.mercurylang.org/deb/ DISTRO main


  *
I run the weird GPG thing that the document tells me to do


  *
I run 'apt update' and then...


[root at Herbert tmp]# apt update
Ign:1 http://dl.mercurylang.org/deb DISTRO InRelease
Err:2 http://dl.mercurylang.org/deb DISTRO Release
  404  Not Found [IP: 45.56.89.38 80]
Error: The repository 'http://dl.mercurylang.org/deb DISTRO Release' does not have a Release file.
Notice: Updating from such a repository can't be done securely, and is therefore disabled by default.
Notice: See apt-secure(8) manpage for repository creation and user configuration details.
Notice: Missing Signed-By in the sources.list(5) entry for 'http://dl.mercurylang.org/deb'

At this point I'm so far down the rabbit hole of Things I Don't Care About While Recovering From The Flu that I'm here to call for help.

Is the right thing to do now to try installing from the sources instead?

Anyway, looking forward to re-connecting with everyone again!

Cheers,
Ralph
