Multiple errors (IPv6 and simply error) #185

Open rodolfo-viana opened 5 years ago

rodolfo-viana commented 5 years ago

(Before posting this issue I read through closed and open issues to check if any reply would help me. No answer was helpful.)

I have been using ProtonVPN command-line tool for Linux for some weeks with no problem, but a couple of days ago I failed to connect. Since then I have been getting either

[!] Error connecting to VPN.
[!] There are issues in managing IPv6 in the system. Please test the system for the root cause.
Not being able to manage IPv6 by protonvpn-cli may leak the system's IPv6 address.

or the generic line

[!] Error connecting to VPN.

I checked IPv6 and it seems fine. I uninstalled and reinstalled ProtonVPN and the issue persists. I get this error when I choose Y and when I choose N when asked to decrease privilege...

So I am not sure what is going on. Can you guys help me please?

Here is my ifconfig output:

Please, post the output of apt list resolvconf and cat /etc/resolv.conf

rodolfo-viana commented 5 years ago

Hi @xilopaint.

apt list -a resolvconf (a because it seems there is one additional version) returns:

Listing... Done
resolvconf/bionic-updates,bionic-updates,now 1.79ubuntu10.18.04.3 all [installed]
resolvconf/bionic,bionic 1.79ubuntu10 all

cat /etc/resolv.conf returns:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 127.0.0.53

Is this info helpful?

xilopaint commented 5 years ago

There's a weird info in your logs:

resolvconf: Error: Command not recognized
Usage: resolvconf (-d IFACE|-a IFACE|-u|--enable-updates|--disable-updates|--updates-are-enabled)

It sounds like a problem with DNS management. But I have the same resolvconf version and it works fine for me. Have you tried to connect with openvpn directly using the config files?

rodolfo-viana commented 5 years ago

I just wrote a line in my .bashrc to connect when I ran my terminal. Something like echo "protonvpn-cli -c". And it would ask for my password, show the screen to select the server etc. It worked for some time and then suddenly just stopped working.

And nothing else.

xilopaint commented 5 years ago

I'm asking if you already tried to connect with a config file:

sudo openvpn <config_file.ovpn>

rodolfo-viana commented 5 years ago

No, I did not. I just followed through this guide.

xilopaint commented 5 years ago

Please, download a config file and try ~sudo openvpn config <config_file.ovpn>~

EDIT: Sorry, the right command is sudo openvpn <config_file.ovpn>

You can find a guide in the Option B on this page.

Hey @rodolfo-viana, have you tried the command in the above post?

rodolfo-viana commented 5 years ago

I did try but got no successful response. So I decided to start activating it via Network Manager.

xilopaint commented 5 years ago

It turns out I might have found the root cause of your issue. Your DNS resolver is systemd-resolved and your system might be lacking /sbin/resolvconf what prevents /etc/resolv.conf from being updated by /etc/openvpn/update-resolv-conf. That's explained here.

You can confirm this by running cat /sbin/resolvconf. If the file does not exist that's your problem. Is your system by any chance Ubuntu 18.04?

@rodolfo-viana could you close the issue if no longer interested in debugging it?
