From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Unable to get IP address via DHCP on HP ProLiant DL380 Gen9 with Debian (lemm.ee)

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.
