ERROR IN UPFATE MANAGER

Ive reinstalled linux mint as was having issues in update manager. after a fresh install- i cant update the error says W: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/universe/s/systemd/systemd-coredump_249.11-0ubuntu3.4_amd64.deb
404 Not Found [IP: my ip adress)

Im new to LInux if it cant be resovled does anyone know any one that can help (maybe over the phone- or local to KENT UK)

Thanks in advance

Ok, that path looks like it’s been replaced … have you doing an “apt update” first?
(current version looks like) systemd-coredump_249.11-0ubuntu3.6_amd64.deb

hi how do i do that?

ive just rebooted several times and it looks like its resolved itself now!

Ctrl+Alt+T to start a terminal

sudo apt update
