"The certificate of 'deb.debian.org' is not trusted" (3 days now)

[WiggleMaster5]

Hi,

So I'm trying to install from an ISO and it's spitting up this error when trying to confirm it's up to date / pull down files.

It's been like this for 3 days now.

I know the VM, has an IP address and the firewall is off.

Is anyone else seeing this?

Is your system clock correct?

You could temporarily switch to a different APT mirror or replace https by http to reinstall e.g. ca-certificates package, probably this helps.
