dns-sd-resolved[60f4d4d6218182ed]: send-updates SetLinkDomains@6 failed: GDBus.Error:org.freedesktop.resolve1.LinkBusy: Link enx00e04c1604af is managed
Oh. You do not use a Router or Modem to manage your Line to your Provider? Like a small Raspberry or Router with dnsmasq and a NAT/Script for Routing the IP-Packages from your Network, over that single Line?
Normally in-House LAN, you’ll have that Modem or Router/WLAN Router to set up that Managed Network.
Your error Message i quoted, which you posted 10h before. Describe that your Link was Busy. And could not resolve your DNS-Request.
That’s why i wrote before about DNS-Forward and DNS-Cache.
If you have two Computers (or more Devices) on the same (Internet)-Line, which sending Messages unmanaged, someone got that Links is busy Error. Its just about Time.
Think about, Data Packages are like Trains on a track and if you try to send two together at the same time, (on one Line from two devices) they will crash. The Signals will overlay and the result is trash if sender and receiver did not communicate well.
If you have Trains with light speed, and they are on a X Miles Way to next Station and Y Miles (1, 2, 16, 20…) long. They need some time to arrive. And some time to start. If two Computers send trains on the same Line, and the Device is busy you will drop or Lost Information.
Sometimes like TCP it will request and remanage to re-send Parts. But it may be Bad with to many Trains on the same Line and firing together.
If you set up a Computer/Router/Accesspoint (just one System from your Home) with a fixed IP in your LAN and Providers Net, which will Manage the different Requests from your LAN to your Internet, DNS-Forward and else. I think you will get rid of your issues. Because this Computer route your Network-Requests in the exact timing to transmit 100% of your packages without timing/packages collisions.
I am not sure if i am 100% right but i think it’s logical.
Your Bug will only accrue if two Devices use your Line together and DNS Requests are frequent, if one Web Page ask for 60 Domains to resolve… for example. With more Devices it will get more uncontrolled and unstable.
Edit: Sorry for this Post, i missunderstood the Error-Message. It is usual for that kind of issue, but you wrote that you allready have a Router Use… is there a way that you still have overlaping signals on some network Line?
This one Errormessage can be a artefact.
