r8168 module not used by ethernet controller

Question

I discovered that my eth0 interface is constantly down (I use wlan0 for WiFi). After some googling I replaced r8169 module with r8168 (apt-get install r8168-dkms), but after rebooting failed to find the 'Kernel driver in use' line:

root@controller:/home/me# lspci -v

Here's output from dkms status:

Also:

modinfo: ERROR: Module r1869 not found.

Now eth0 interface is absent in the ifconfig -a output, probably because r8168 wasn't detected at startup.

Can anyone tell me what I've done wrong or forgot? Thanks in advance!

You should not make massive changes to a question after it has been answered. Please post a new question instead. — muru, Dec 27 '16 at 13:21

Turn off secure boot in your BIOS. Ubuntu will not load unsigned kernel modules with this enabled.

edit:

The r8168-dkms is not the right driver for your Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller (rev 07).

To uninstall it:

sudo dkms remove r8168/8.043.02 --all # to uninstall r8168 kernel module

sudo apt-get purge r8168-dkms # to uninstall r8168-dkms

Make sure that the file /etc/modprobe.d/r8168-dkms.conf does not exist.

Reboot the computer.

Edit your question to include the terminal output of the first 3 lines of modinfo r8169, and sudo lshw -C network

You will have to download the rtl8101 driver from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=7&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false#2

Follow the instructions in the README file contained in the download file, and review this Realtek ethernet driver error ubuntu 16.04 (starting with the answer that contains "For product: RTL8101/2/6E PCI Express").

Hi heynemma! I tried this, but with no results - still no eth0 and r8168 not seems to be used by the controller. – edward ziyangulov Dec 26 '16 at 07:52
@edwardziyangulov Edit your question to include the terminal app output of the command dkms status. – heynnema Dec 26 '16 at 14:17
Follow the PENDING instructions in my answer, and STOP where it says stop here. – heynnema Dec 26 '16 at 15:47
You're a magician! :) I've run the ./autorun.sh, and now I see my eth0 interface in ifconfig. – edward ziyangulov Dec 26 '16 at 17:16
I'm a newbie to AskUbuntu, what can I do for you - raise your rating, etc.? – edward ziyangulov Dec 26 '16 at 17:17
In my case, sudo apt-get autoremove was needed as well. Now the troubles caused by r8168 are fixed, thank you! – Pavel V. Oct 24 '20 at 07:08
