When installing LAMP server, I went for tasksel, and got my DE (Xfce) and seemingly also display manager (LightDM) removed (this is a known "bug", believe it or not). Now I just need to connect to wifi to start reinstalling the removed components.
However, it seems there's very little to start with. I have no wireless interface (
ifconfig -a shows only
lo). I have no
ifdown. By way of relevant tools, I have at least (and maybe only)
systemctl status network-manager shows that
network-manager.service is loaded and inactive (dead). I can activate it w/
systemctl restart network-manager, but that's it. I edited /etc/network/interfaces, to include the wireless info, as described here, and rebooted. This bought me nothing.
lspci -v assures me I (still) have Intel Wireless 8265 / 8275 network controller. The question: Is there anything I could try to do to connect to wifi other than a complete reinstall of the distro? Something to get things going. I'm on Ubuntu 18.04 LTS
