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. – mikewhatever Feb 01 '22 at 17:17
  • @mikewhatever after over an hour, still the same. Will ping this tomorrow if persists – Gulzar Feb 01 '22 at 18:27

    Please try main server or another mirror. – nobody Feb 01 '22 at 19:13
  • 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) – guiverc Feb 02 '22 at 00:11

    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. – Thomas Ward Feb 02 '22 at 01:14

I agree with what's already provided via comments by @mikewhatever or @nobody

Instead of using your current mirror.isoc.org.il

use another found on https://launchpad.net/ubuntu/+archivemirrors (or use the main archive/server)

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. – Thomas Ward Feb 02 '22 at 01:13

    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... – guiverc Feb 02 '22 at 01:35

    Please specify how to use another mirror so I can accept the answer. – Gulzar Feb 03 '22 at 10:06
  • A great explanation on how to edit /etc/sources.list on Debian and Ubuntu https://unix.stackexchange.com/questions/372736/how-to-edit-sources-list-as-root-under-debian-9 and a a complete tutorial: https://www.addictivetips.com/ubuntu-linux-tips/ubuntu-sources-list-editing-guide/ – Fernando Kosh Jun 02 '22 at 14:16
  • If using Lubuntu, have you tried looking in the manual? ie. https://manual.lubuntu.me/lts/4/4.3/software_sources.html (link currently shows 20.04 manual link) displays in the first picture a dropdown for "Download from" though selection is from 579 current mirrors listed in https://launchpad.net/ubuntu/+archivemirrors but may not be all. This detail can be changed many ways though. It's the same with other desktops too, just different menu options. – guiverc Jun 02 '22 at 22:36
