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?
Do you have another NIC? Maybe the card died?
Immediately after I installed Debian and before I booted into it? I guess I could try installing it again to see if the installer has internet still
You seem to be doing everything right including software wise. I would try to see if the card is dead. If you can rule that out, then you can continue trouble shooting. I am just trying to rule out simple answers.
