I deleted both the resolvconf folder and the resolv.conf file in /etc by mistake, assuming that resolvconf was causing UCK to fail. Now the application has upgraded, fixing the issue, but it says no file named resolv.conf in /etc. What it says is correct because I deleted those files. Is there any way to recreate the files or restore from another location?

You could reinstall resolvconf to restore the default configuration:

sudo apt-get install --reinstall resolvconf

Another idea would be remove "resolvconf" and then install:

sudo apt-get remove --purge resolvconf && sudo apt-get install resolvconf

If resolvconf -u shows the WARNING that /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf then just backup that resolv.conf and make the symbolic link:

$ cd /etc $ sudo ln -s /run/resolvconf/resolv.conf

Try this:

nano /etc/resolv.conf

add:

nameserver 8.8.8.8

nameserver 192.168.x.x (check your ifconfig output for the correct address)

then

sudo service resolvconf start sudo systemctl enable resolvconf

The accepted answer did not work for me. After reinstalling resolvconf, the system would completely wipe my resolv.conf file after each reboot.

To fix this, I had to reinstall the network-manager and libnss-resolve packages in addition to resolvconf.

  1. Manually add a nameserver to resolve.conf (this is so you can fetch packages from the Ubuntu repos):

    1. sudo vi /etc/resolv.conf
    2. Add nameserver 8.8.8.8 to the file.

  2. Reinstall the network-manager, libnss-resolve, and resolvconf packages:

    apt install --reinstall resolvconf network-manager libnss-resolve

Have you emptied your trash, if not, you can restore from trash.
