Probably because I unselected all the default lists, but of course that doesn't cover the other issues.
OK, fair enough. I was alarmed at that suggestion right off the bat but yeah it does seem a lot of stuff is broken for some reason. I downloaded the Buster live image last night in preparation because the this whole thing started from using the netinstall in the 1st place.
Fun fact: I run Windows 10, (a Free)BSD( fork), and multiple Linux distros across 10 machines, and this is the 1st time I've had to reinstall an OS from scratch to fix a problem since 2006/7. Every other issue I've ever had has been fixable in the same installation. Also my 1st time using Debian, so that might be it.
Thanks for your assistance. Reinstallation it is!
UPDATE: Reinstalled from scratch using just the KDE live CD ISO and everything appears to be working.
Lessons learned:
- Keep the base OS image as simple as you can manage
- Use the Debian live CD installer, not netinstall
- Don't select the webserver option during Debian installation
Thanks all for your assistance.
I figured out why this is the case. If you use KDE, ensure the machine is configuring the network connection with an IPv4 address and not an IPv6 one. To check and fix that, do the following:
- Right-click the network connection icon in the system tray
- Click Configure Network Connections...
- In the Connections - System Settings Module window that pops up, in the list on the left, click the wired network connection via which machine is connected to the LAN
- Under the Wired tab on the right, check the Allow auto-negotiation option
- Click Apply
- Under the IPv6 tab on the right, change the value of the Method dropdown to Ignored
- Click Apply
- Click OK
- Reboot the machine
This should allow the OS to autonegotiate and IPv4 address for the network connection.
