"Connection timed out" indicates some kind of networking problem. Are you connected to the network? What network troubleshooting have have you already done? — user535733, May 08 '20 at 18:45
i have no network issue i can ping 8.8.8.8 and google.com and also no network error i get — Jimmy Mij, May 08 '20 at 18:47
Try sudo apt update again. If it still fails, then you have an ISP problem (except for the one that really doesn't exist anymore, of course). — user535733, May 08 '20 at 18:59

Let me go over the three basic troubleshooting steps that will solve most of things:

Check Power (is the modem / router turned on, is the adapter turned off (wifi), etc)
Check your connections (check cables: are they properly plugged, try re-seating, are they in the correct place, etc) Some of us would have added after this to check on which side of the keyboard is the problem occurring :P
Only then try to look further into configurations, software, etc.

With Networking Troubleshooting The basic idea is

Try to ping your modem/router.

example A: ping 192.168.0.1 (whatever the IP of your gateway is)

If you succeed try to ping a known IP (example 1.1.1.1 or 8.8.8.8)

example B: ping 1.1.1.1 (or whatever server you know is usually always up, (and replies))

If you succeed try to ping a website (google.com)

example C: ping google.com (or whatever website you know normally is up and replies)

You are basically working your way out of the network, because if you can't even ping your gateway the problem is within your device or between. But if you can get to outside IP's but not names, then your issue is DNS (resolving names to IP's)
