    Check your DNS resolve. Try in command line `nslookup deb.debian.org` – Romeo Ninov Dec 08 '22 at 08:24
  • Romeo Ninov when I run 'nslookup deb.debian.org ' I get this reply: ;; connection timed out; no servers could be reached – tlholoheloh101 Dec 08 '22 at 08:29
  • Try to set your DNS to 8.8.8.8 for example and try again – Romeo Ninov Dec 08 '22 at 08:50
  • @Romeo Ninov I configured the DNS to 8.8.8.8 but it doesn't work still getting same error. The browser is not accessing the internet as well. – tlholoheloh101 Dec 08 '22 at 08:57
  • Do you have internet access at all on this machine? – Romeo Ninov Dec 08 '22 at 08:58
  • @Romeo Ninov it seems that I do not have internet access at all, the server was connected and working fine until Monday when an administrator was installing company specific software and lost ssh connection, since then there is no internet connection or ssh connection and I cannot apt-get update. Can you suggest some configuration that I can use to get it up and running again please – tlholoheloh101 Dec 08 '22 at 09:04

    talk to whomever is responsible for your DNS server and/or your network and configure a working DNS server. – Gerald Schneider Dec 08 '22 at 09:09
  • @Gerald Schneider thanks, will do and give feedback – tlholoheloh101 Dec 08 '22 at 09:15
  • I can ping 8.8.8.8 and the other 3 servers but I cannot ping Google.com or extract downloads from other url's on the internet and the internet browser has no internet access. Reply "failure name resolution" Server3 is cluster 3 and static IP /61 GW is /57 which is cisco switch 1. Switch 1 interconnected to Cisco router 1 and Router 2, FW 1 is currently bypassed. VIP /58. Still " FAILURE NAME RESOLUTION " – tlholoheloh101 Dec 13 '22 at 07:14

This worked for me:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null
