Dnscrypt-proxy: Systemd service failed to run on Linux Mint 19

[seth100]

Hi,

I did:

$ sudo add-apt-repository ppa:shevchuk/dnscrypt-proxy && \
sudo apt update && \
sudo apt install dnscrypt-proxy

and followed all parts under https://github.com/jedisct1/dnscrypt-proxy/wiki/Installation-Debian-Ubuntu#configuration

Then done:
$ sudo systemctl restart NetworkManager
$ sudo systemctl restart dnscrypt-proxy

But failed:
$ sudo systemctl status dnscrypt-proxy

Looks like these instructions don't work, then :(

Remove everything and follow the generic installation steps instead: https://github.com/jedisct1/dnscrypt-proxy/wiki/Installation-linux

I think you forgot to change:

listen_addresses = ['127.0.0.1:53']

to

listen_addresses = ['']

Granted, the page had a diff output supposed to suggest this, but it was very hard to read.

@jedisct1, thank you it works now the service, after setting listen_addresses = ['']!

The problem now is that after setting 127.0.0.1 from GUI as DNS (not auto DNS) internet does now work anymore. It can't succeed in resolve addresses.
Am I missing anything?

Thanks

Ps I think you had a typo here:
you wrote:
In dnscrypt-proxy.toml, replace listen_addresses = ['127.0.0.1:53'] with listen_addresses = ['127.0.0.1:53'].

but should be:

In dnscrypt-proxy.toml, replace listen_addresses = ['127.0.0.1:53'] with listen_addresses = [].

right?

[jedisct1]

Good catch for the typo. Fixed, thanks!

Any tip for my problem?

Got the same problem since 2.0.15, am on Ubuntu 18.04.

[jedisct1]

Don't use systemd sockets activation, and all your troubles will go away.

[MinIsMin]

Then I still have the problem seth mentioned first (permission denied on all ips with port 53)

[jedisct1]

Remove all the dnscrypt systemd service files, and install the service with dnscrypt-proxy -service install.

Thanks, now it's working fine!
