Removed resolv.conf, connected to network, but no internet connection

[Mo0rBy]

I removed resolv.conf in order to clear my DNS settings, thinking that it would auto-regenerate on reboot, but it has not, and I can no longer connect to the internet. I can’t post the detailed information of the inxi command due to having no connection on the machine, so I can’t copy paste it.

I’ve tried a few things to fix this issue:
sudo resolvconf -u
sudo systemctl restart NetworkManager

I tried sudo touch resolv.conf and sudo nano resolv.conf but both give me No such file or directory (nano does it when I try to save and exit the editor).

not sure if this will work but is there any /etc/resolv.conf??

if not then paste the output of cat /run/NetworkManager/resolv.conf to that file and try again

Hi @Mo0rBy,

If you are % sure that it’s all, you can, theoretically just recreate it with the correct owner and permissions. Here is mine as example:

$ cat /etc/resolv.conf

# Generated by NetworkManager
search example.com
nameserver 8.8.8.8
nameserver 8.8.4.4

After which you should set the correct owner and permissions:

sudo chown root:root /etc/resolv.conf

and

sudo chmod 0644 /etc/resolv.conf

Followed by rebooting and seeing if it works.

If it does, then just for good measure, reinstall NetworkManager

pamaac reinstall networkmanager

I can’t recreate the file with nano or touch. When I try to save and exit nano, I get [ Error writing resolv.conf: No such file or directory ] and when i do sudo touch resolv.conf I get touch: cannot touch 'resolv.conf' : No such file or directory.

So I can’t even create before changing owner/permissions etc.

Also, I don’t have the pamaac package manager installed, I think i just have pacman and nothing else.

[Mo0rBy]

I do get an output for the cat command

# Generated by NetworkManager
nameserver 127.0.0.53
options edns0 trust-ad

However, I can’t create a new resolv.conf file with touch or nano, I just get No such file or directory, which is strange, because I’m, CREATING the file, so of course it doesn’t exist.

[Mo0rBy]

I tried pacman -S networkmanager and it fails to download the .pkg.tar.zst file and fails to resolve hostnames got loads of stuff (which makes sense as I dont have internet connection because of this issue)

What is the output for

sudo ls /etc/res*

[Mo0rBy]

/etc/resolv.conf /etc/resolvconf.conf

So this says that resolv.conf does exist?

[Mo0rBy]

I just did sudo rm resolv.conf no errors. Then did sudo nano resolv.conf and I was able to save it with the output of the previous cat command. Restarting now to see if it works.

[Mirdarthos]

That’s exactly what I was about to suggest.

[Mo0rBy]

YES, thank you, that did trick. Very strange behaviour, do you know any guesses why it was like that?

[Mirdarthos]

None whatsoever. Just make sure the ownership and permissions are correct as per my previous post.
