I have no idea what went wrong, and found no clue as to what do do.

I really don't want to have to reinstall everything again.

"Mirror sync in progress?" Wait 15 minutes, then try again.

Please try main server or another mirror.

I agree with what's already provided; ie. instead of using your current `mirror.isoc.org.il` (https://launchpad.net/ubuntu/+mirror/mirror.isoc.org.il-archive) use another found on https://launchpad.net/ubuntu/+archivemirrors (or use the main archive/server)

Wait a few hours, sometimes a day, then try again. A lot of times mirrors can be slow to finish updating, and will update at a later point if they're configured right. If this continues to fail, I would fall back to `archive.ubuntu.com` and use the default archives instead of your country mirrors.

If you don't want to change your sources/mirror; you'll need to raise a ticket with your current mirror/archive so they can look at it and fix it. Chances are though; the issue will have resolved itself (next sync will almost certainly fix it) before they actually get around to looking at the issue.

The alternative NOT mentioned here is "be patient and wait for the mirrors to finish syncing". You get the error that OP mentioned MOST FREQUENTLY during a sync process.

I thought that was *implied* with the "*Chances are though; the issue will have resolved itself (next sync will almost certainly fix it) before they actually get around to looking at the issue.*" but my intent isn't always as *obvious* as it should be...

Please specify *how* to use another mirror so I can accept the answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
