Repository expired

Attempting to install the2.7.0.14 linuxCNC, but attempting to use Synaptic Package Manager to install emacs, ddd and other useful tools finds no packages. Using apt-get gives a message about the wheezy updates/Release "is expired". Solution?

Wheezy has been archived a while ago (there are no updates, no need to get freaked out), you need to update the repo to
deb archive.debian.org/debian wheezy main

This page does more justice:
serverfault.com/questions/960970/wheezy-...eturns-404-not-found

I wouldn't get too freaked out by the security warning at the end of the article. There is not a big risk of your milk going sour, chickens not laying and rivers running dry.

Did that. sudo apt-get update still complains about the expired repository. I installed this ISO in a VM under Windows 10 a few months back, and Synaptic Package Manager still works there.

What exact expired repo is it exactly complaining about ?
The Wheezy repos were archived June 2018.
The actual error output and you apt sources will help. Include any in the /etc/apt/ directory and /etc/apt/sources.list.d/ directory.

Theoretically if you copy the /etc/apt directory from the VM to other machine it should all be good.

I just installed Linuxcnc 2.7.14 via the official iso and this is the contents of my /etc/apt/sources.list

used this to run
And all was good.

Thank you. You solved my problem.

And what does it mean archived?
Will they no longer develop?

Ogogon.
