Certificate verification failed: The certificate is NOT trusted Ubuntu 20.04

I haven't changed anything in my ubuntu, and all of a sudden this error showed up when I tried to update.
I tried to do some changes as I saw in google and nothing changed.

I would love to get some help.
thanks!

Actually, not so much, because I have no idea what to do with this address shown in the error:

https://il.archive.ubuntu.com/ubuntu.

Is it possible that they stopped the support on 20.04?

No, 20.04 is LTS. If you put the effort in, it's supported for 10 years.

It may be that there's issues with the server - so change your download servers to something else. That's on the drop down menu for software sources, first tab. You can try that.

The others will likely need to be removed - and possibly re-added after you get this back up and updating properly.
