Does Not Work.

[Marcelo Marchi Negreira]

DNSCrypt-Proxy does not work in Ubuntu 22.04 LTS, even with net manager configured for 127.0.2.1 or 127.0.0.1
No connection with DNS servers.

Status changed to 'Confirmed' because the bug affects multiple users.

[Pascal Mons (anton+)]

However, the build from this PPA is working fine. Mainly the /etc/dnscrypt-proxy/dnscrypt-proxy.toml file has kept its original GitHub developer website posting ... Further proof the Debian.org alterations are just pure bullshit ...

https://launchpad.net/~shevchuk/+archive/ubuntu/dnscrypt-proxy/+packages

Or download the .deb file and proceed with $ dpkg -i dnscrypt-proxy_2.0.45~ppa2_amd64.deb

You can as well un-comment the resolver_names line and add / remove resolver(s) in that file which list is maintained on the original developer website as well :

https://dnscrypt.info/public-servers/

In the end, I just changed the DNS for IP v4 to 127.0.2.1 and it's equally working great!

Of course you still need to prevent Ubuntu updates on that package.

$ sudo echo "dnscrypt-proxy hold" | dpkg --set-selections

To re-authorize update

$ sudo echo "dnscrypt-proxy install" | dpkg --set-selections

That's it.

[NOTE]: $ journalctl -xeu dnscrypt-proxy.service

will provide a list of dns server with their latency

I am unable to reproduce this problem in Jammy. Installed dnscrypt-proxy and modified /etc/dnscrypt-proxy/dnscrypt-proxy.toml to add more servers, and then restarted dnscrypt-proxy.service. After that "journalctl -xeu dnscrypt-proxy.service" is showing me the following log which I think shows that its working.
