nextdns: Unifi UXG Pro does not work

There is now a total of $225 pledged to solving this issue on BountySource.

Right now thats even more 😀 375, but no updates so far. @rs Maybe you can help?

@rs could this issue be re-opened please?

Thank you! 🙂

Poking around with some of the install script’s FORCE_* ENVs to no avail. Even if the installation seems successful, running the nextdns binary (for any of the subcommands besides version) results in: system not supported. On the plus side, that means the architecture of the binary is correct and that it executes. I think it’s tripping over some of the checks for the ubios platform like: https://github.com/nextdns/nextdns/blob/90dca2ec199308d69578dc5cdfd99046a805ba72/host/service/ubios/service.go#L28-L30

I’ve included a ton of info from my UXG Pro. I’ve also got 2x uSgs at my disposal. Let me know if there anything else I can help with.

Congratulations! NextDNS is now installed.

To upgrade/uninstall, run this command again and select the approriate option.

You can use the nextdns command to control the daemon.
Here is a few important commands to know:

# Start, stop, restart the daemon:
nextdns start
nextdns stop
nextdns restart

# Configure the local host to point to NextDNS or not:
nextdns activate
nextdns deactivate

# Explore daemon logs:
nextdns log

# For more commands, use:
nextdns help

# nextdns start
system not supported
# nextdns activate
system not supported
# nextdns log
system not supported
# nextdns version
nextdns version 1.37.11

It’s unclear to me what the analog for some of these checks would be for the UXG Pro’s UbiOS as it seems novel compared to the USG.

No i just used the defaults, with Router I said yes. After that I rebooted and it worked. However, since I dont ‘trust’ it keeps working I have removed it now and went for the normal DNS via IP in the UI.

My friends, firmware UXG Pro 3.0.7 allowed me to install sh` -c ‘sh -c “$(curl -sL https://nextdns.io/install)”’ without any workarounds, NextDNS after almost 2 years is now running on my UXG Pro!
