root@sunimali-HP-ProBook-450-G6:/home/sunimali# dhclient vpn_vpn
cmp: EOF on /tmp/tmp.EnmkqhupY9 which is empty

  • Please use copy and paste from the terminal for the error messages rather than using a screenshot. –  Jun 29 '20 at 08:18

    @LoïcReynier thanks for feedback, I updated the question – Malie_Rath Jun 29 '20 at 08:29
  • Does ```sudo dhclient``` without arguments work for you? Can you please append the output of the command ```sudo dhclient -v``` to your post? – Parsa Mousavi Jun 29 '20 at 09:37
  • @ParsaMousavi this is the out after sudo dhclient: sudo dhclient [sudo] password for sunimali: RTNETLINK answers: File exists cmp: EOF on /tmp/tmp.qlfvdHMZt4 which is empty – Malie_Rath Jun 29 '20 at 10:40
  • @ParsaMousavi I updated question with sudo dhclient and sudo dhclient -v outputs – Malie_Rath Jun 29 '20 at 10:43

To resolve this part

cmp: EOF on /tmp/tmp.EnmkqhupY9 which is empty

You can try adding your local hostname to /etc/hosts

127.0.0.1 localhost
127.0.1.1 <your hostname>

  • This worked perfectly for me. Thank you! I had changed the hostname in the past and `/etc/hosts` still contained the old one. – user643011 Dec 30 '20 at 14:59
