/run/resolvconf/resolv.conf gets erased each time I restart, and I can't use internet without it (16.04)

Question

I have been solving issues with my ubuntu - windows partition. So after having an issue with the clock of the system and i think this triggering that I couldn't log into my user (it just bounced back) but being free to log like guest, so I created a new user like suggested here.

So, it worked, but now I couldn't load anything although the icon appeared like connected, both wireless and ethernet. So I found a solution... somewhere, that said to add to /etc/resolv.conf

nameserver 8.8.8.8

nameserver 8.8.4.4

So, I found it but it had a symlink to /run/resolvconf/resolv.conf and it didn't exists, so I made one with only said lines. And the internet worked then!!

But when I restart the computer, /run/resolvconf/resolv.conf is gone so I have to make one again each time.

How can I fix this? Apparently there aren't any other symlinks broken, and I have also done this with no result. Thanks everybody

Solution 1

You should restore the resolv.conf symbolic link and add required nameservers to /etc/resolvconf/resolv.conf.d/base. Follow these steps:

1. Reinstall resolvconf package:

   $ sudo apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall resolvconf
   

2. Add required nameservers to /etc/resolvconf/resolv.conf.d/base:

   $ sudo bash -c 'echo "nameserver 8.8.8.8" >> /etc/resolvconf/resolv.conf.d/base'
   $ sudo bash -c 'echo "nameserver 8.8.4.4" >> /etc/resolvconf/resolv.conf.d/base'
   

3. Regenerate resolv.conf:

   $ sudo resolvconf -u
   

4. Restart your network interfaces:

   $ sudo ifdown -a ; sudo ifup -a
   

Solution 2

I think the resolv.conf is not updated automatically. You can reconfigure it

sudo dpkg-reconfigure resolvconf

Try running sudo dpkg-reconfigure resolvconf and answering 'Yes' when it asks you if you want to prepare /etc/resolv.conf for dynamic updates.

@Antonio Kuri Have you tried some of these solutions?

[Admin]

Yeah, I just did. Something is missing

@AntonioKuri I've updated my answer. Try from the beginning again. Changed step 1.

When running step 3, it gives back: run-parts: failed to open directory /etc/resolvconf/update.d: No such file or directory

[Antonio Kuri]

It does make that persistent but doesn't help to fix the connection. No site loads

NetworkManager just crashed while doing nothing. Executable path: /usr/sbin/NetworkManager

[Thiago Rider Augusto]

Did you tried restarting NetworkManager?

[Antonio Kuri]

Doing the stated worked. Now I restart and the connection works just fine. Thanks
