Please advise (not an expert, please keep it clear and simple):

I installed Ubuntu 18.4 on my HP 15 laptop. Everything else I managed to fix but Ubuntu does not find WIFI. I googled and tried several suggested solutions but the solutions I tried did not work did not work because there are "broken packages".

How do I

  1. Fix broken packages?
  2. Fix WiFi?

  • Do you have ifconfig installed on the machine? Try running ifconfig in a terminal and add the output to your question. – Chris Sullivan Jan 02 '19 at 19:30
  • Here is an excellent question about checking what driver you have, as well as the steps needed to install a PCI compliant driver. https://askubuntu.com/questions/333424/how-can-i-check-the-information-of-currently-installed-wifi-drivers – Chris Sullivan Jan 02 '19 at 19:33
  • I did that and got: 'ifconfig' not found. Can be installed:

    sudo apt install net-tools

    I did that. This is the end of the output libdvd-pkg: Checking orig.tar integrity... /usr/src/libdvd-pkg/libdvdcss_1.4.2.orig.tar.bz2: OK libdvd-pkg: apt-get check failed, you may have broken packages. Aborting...

  • lspci | grep -i network gave me this: *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:3000(size=256) memory:a1100000-a110ffff – koppuli kappilka Jan 02 '19 at 20:07
  • Did you tried running sudo apt install --fix-broken on a terminal window (ctrl+alt+t)? – Pablo Bianchi Jan 02 '19 at 21:31
  • May we see: lspci -nnk | grep 0280 -A3 Welcome to Ask Ubuntu. – chili555 Jan 02 '19 at 22:16
  • @Pablo Bianchi Installed 18.10 and during installation the system found WIFI and Bluetooth but once done both disappeared. Then, I disabled Secure Boot. Did the --fix and lspci please see below. Still no WIFI or Bluetooth 02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.

  • @ chili555 AND suddenly THE WIFI WORKS!!!! :) Disabling secure boot was the solution. Now I just have to find a way to fix the dual boot.... – koppuli kappilka Jan 04 '19 at 11:28
  • AFAIK secure boot have nothing to with WiFi/network. Please update the question with the output of inxi -SMn && lspci -nnk | grep 0280 -A3 (what @chili555 asked and a little more). – Pablo Bianchi Jan 04 '19 at 18:43

    @PabloBianchi Please see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1806472 From the bug report: "Yep, disabling Secure Boot seems to allow the driver to load no problem." – chili555 Jan 04 '19 at 21:35
