Package: ifupdown
Version: 0.8.41
Severity: normal
Dear Maintainer,
I was doing my network setup, which included statically configured
logical interfaces. So there were dns-nameservers entries in my
/etc/network/interfaces. My configuration files is below (the actual
IPs and MACs is wiped).
I noted that ifup with my setup is producing error messages like this:
...

I have found discussion about similar problem there:
https://unix.stackexchange.com/questions/714901/dns-broken-when-using-ifupdown-and-systemd-resolved-after-upgrade-to-ubuntu-22-0
Also I had a look into the /etc/network/if-up.d/resolved and I assume
this is a typo in the line 69:
https://salsa.debian.org/debian/ifupdown/-/blob/master/debian/if-up.d/resolved#L69
Then I edited mine /etc/network/if-up.d/resolved this way:

And now it works well.
I'm guessing that someone might also have a static network
configuration at the same time as systemd-resolved installed, so I hope
this information can help someone.
Kind regards,
Dmytro
