I have the same problem; I’m trying to run AdGuard Home (v1.3.13), but can’t use port 53: conflicts with ‘Virt Service’.
I have tried the incus command, above, but this doesn’t appear to change anything which allows AdGuard to install / work.
And, although my router doesn’t allow use of a non-standard port, I did try setting AdGuard to port 54, just to see if the install/update would complete with that (it does). Now, though, the AdGuard ‘Setup Guide’ still refers to port 54 even if I set the port back to 53 and enable ‘Host Network’ (the only other way I can get the install to complete). And I don’t believe I want ‘Host Network’ enabled.
Edit(1): I can now get AdGuard to complete installation with port 53 set, by setting the ‘Host IP’ to the address of my TrueNAS, i.e. “‘192.168.0.2’ IP Address”. Which is odd, because I’ve never been able to get that box to take an actual IP address before, only “‘0.0.0.0’ IP Address”. The Application Info now does report that, amongst the Ports being used, it’s using “tcp://192.168.0.2:53 : 53” (it didn’t do that, before).
However, I still can’t get DNS queries to work, if I put that address in as my router’s DNS server. So, the TrueNAS box on 192.168.0.2 is set to direct DNS queries to the router on 192.168.0.1, which then sends those back to the TrueNAS box on 192.168.0.2:53. Could this be a problem?
And, the ‘Setup Guide’ in AdGuard still refers to port 54, not 53.
Edit(2): I’ve just realised that I probably need to set an upstream DNS server, in AdGuard. If that’s so, then I’m a doofus.
Edit(3): Nope, AdGuard is still not reporting any queries.
