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 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 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''

@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...
