I assume that this may have been a temporary network problem.

If you re-try the command "sudo apt update" three times in a row, do you still get the same error messages?

Tunc TUNCBILEK (tunc2bilek) said : #2

I tried for 6 hours but same

Manfred Hampl (m-hampl) said : #3

Do you use a web proxy for internet access?

Have you tried changing to a different mirror server?

Tunc TUNCBILEK (tunc2bilek) said : #4

I tried 5 different mirrors, all servers same. I'm not sure about web proxy because i don't have control of network in front of my servers.

Tunc TUNCBILEK (tunc2bilek) said : #5

Network admin added a new rule : ) They reverted it and problem solved. Thank you
