Anyone updated a very standard debian desktop install to Trixie, finding it unable to resolve (yes, it _is_ DNS!).

DNS servers manually input in (stupid) default network manager graphical configuration tools (also manually set in stone in /etc/resolv.conf) can be pung... but no resolution happens...

#techsupport #itsDNS #debian #trixie #fcksystemd < in advance

long story short i ended up making a fresh Trixie install, which took 1-2h total, after spending a good 6h trying to figure that out... with dependency hell on a systemd-resolved that was _not_ installed in what appeared to have been a badly updated (!) system....

lessons learned: i think i dislike systemd even more now, and will stick to devuan on my main machine.... debian still r0x though.

thanks to everyone to weighed in with support and insightful suggestions!

@jz after full-upgrade . The usual /etc/apt/sources.list and *.list files in /etc/apt/sources.list.d/ are replaced by new files, located in the same directory, but with the .sources extension and using the more readable and structured deb822 format. convert all your existing files to this format, you can run:
''apt modernize-sources''

@jz It would have been much more productive to find out what was broken before killing everything, and if by asking for help. But this way your rumbling makes no much sense.

I don’t like how some changes around systemd-resolved have been implemented. But nothing in it should break traditional use of /etc/resolv.conf, and if you had to change it by hand.

@jz Sounds like a Debian or apt issue… systemd-resolved works fine on my Fedora machines… Systemd rocks!

@jz probably systemd-resolved to blame. maybe look if the contents of /etc/resolv.conf change.

("chattr +i" helps with files changing ;)

@bonifartius maybe...? i removed any "connection" in the network-manager graphical interface, and configured manually /etc/systemd/network/lan.network to my parameters, including DNS server, etc..

What is comical is i find this: https://unix.stackexchange.com/questions/442598/how-to-configure-systemd-resolved-and-systemd-networkd-to-use-local-dns-server-f

and

https://serverfault.com/questions/1008355/adding-a-new-dns-server-with-systemd-resolved

but i dont even have the systemd-resolve command, nor resolvectl .... and hard to install them as i am... offline :)

maybe i didnt upgrade correctly?

pfff...

How to configure systemd-resolved and systemd-networkd to use local DNS server for resolving local domains and remote DNS server for remote domains?

I'm connected to local area network with access to the Internet through gateway. There is DNS server in local network which is capable of resolving hostnames of computers from local network. I would

(unsure now, as resolvconf returns my dns servers for my interface!)

@jz oh my.

guess the old rigged together stuff using dnsmasq was just fine :)

@ploum oui cela ressemble à ça... mais ça marchait avant le passage à Trixie... je vais faire le menage dans /etc/network...

pffff ces jeunes avec leur systemd, j'te jure....
