Where to set manual DNS with vpn boot script?

Sounds like you have more serious problems with your setup if you can’t edit that file with sudo.

Can you post the output of sudo ls -al /etc/resolv.conf?

Hi @yknivag
the command gives the following output

-rw-r--r-- 1 root root 137 May 15  2016 /etc/resolv.conf

So yeah, I am running everything as user=osmc .
I tried this:

osmc@osmc:~$ sudo chown osmc:osmc /etc/resolv.conf
chown: changing ownership of '/etc/resolv.conf': Operation not permitted

and

osmc@osmc:~$ sudo chmod 777 /etc/resolv.conf
chmod: changing permissions of '/etc/resolv.conf': Operation not permitted

sudo su puts me in root@osmc

Whats the output from mount

I wanted to just check how your file system is mounted as I was expecting there and issue.
Really getting less ideas. Upload full logs with grab-logs -A maybe we find something

Greatly appreciated.
Here we are: http://paste.osmc.io/ronuhugafu

A bit of context. The system has been updated since a fresh install about 9 months ago I think.
As can be seen from the first post, I have tried to apply a script for openvpn to start at boot.
At the moment I believe the script is not running, however openvpn does connect automatically. Although not with the DSN server.
Checking the status of rc.local says that the process has failed.

update: the vpn is not running at the moment using the current settings.

Can you post the outcome of:

echo Test > test
cat test

And also
cat /etc/passwd

first

osmc@osmc:~$ echo Test > test
osmc@osmc:~$ cat test
Test

second

Had you set a root password in the past?
If yes can you try su and then change the file?

I do not recall setting a password., but su prompts me to input it though.

Try to reset it with sudo passwd

nice, I was able to reset the password, it now reads rialto

Can you now do su and change your files?

can you please guide me threw the steps?

I can log in as root@osmc

root@osmc:~# chmod 777 /etc/resolv.conf
chmod: changing permissions of '/etc/resolv.conf': Operation not permitted

Can you change the content as root?

ie as root, can you issue:

nano /etc/resolv.conf make a change and save it with CtrlO? Or does it say read-only there also?

If it does then there is something very seriously amiss and you may be best off with a clean install.

A permission error remains while logged in as root.
I tried adding a line to nano /etc/resolv.conf
got a permission denied prompt while saving.

I think I’ll be working on a full clean install.
Can anyone direct me to a good tutorial for openvpn that is tailored to OSMC?

Also, I would like to thank @yknivag @fzinken @sam_nazarko @joakim_s @ActionA and @jimblazin for helping me with this issue!

Yes, clean reinstall makes sense (and avoiding none official addons in the future).
For openvpn there are a couple of threads in the forum just search.
