I’m having trouble getting an IP address via DHCP on my HP ProLiant DL380 Gen9 server running Debian. I’ve tried various troubleshooting steps, but nothing seems to work.

Error messages:

  • “No DHCPOFFERS received”
  • “No working leases in persistent database - sleeping”
  • “Activation of network connection failed” (GNOME)
  • “IP configuration unavailable” (Plasma)

Hardware:

  • HP ProLiant DL380 Gen9 server

Software:

  • Debian operating system
  • GNOME and Plasma desktop environments

Troubleshooting steps:

  • Checked network cable and ensured it’s properly connected
  • Restarted network service
  • Set /etc/NetworkManager/NetworkManager.conf managed=true

Additional information:

  • Internet worked during the Debian installation process, but not after booting into the installed system.
  • The problem occurs on both GNOME and Plasma desktop environments, but Plasma provides a slightly more helpful error message.

I’d appreciate any help or guidance on resolving this issue. Has anyone else experienced similar problems with DHCP on a HP ProLiant DL380 Gen9 server with Debian?

    You might have to bring this question over to the Debian Forum. I don’t work with servers, but as noted above this sounds like a situation where you need to install a newer version of the kernel.

    You could try using the Testing ISO https://wiki.debian.org/DebianTesting

      Not necessarily as that hardware is older. It is better to check to see what is in dmesg and ip a first.
