sascha, are you able to provide information about a reproducer
environment for this? I'd like to see this fixed but we need to have a
way to make sure the change actually fixes things.

The change is trivial and I'm going to upload it to the jammy SRU queue,
but we need a test case in order for this SRU to be accepted. If
someone affected by this bug can please detail how to reproduce the
issue *without* having to first generate a new installer image, that
would be useful.

I'll also add that installers for past LTS Ubuntu releases do work in
our environment.
I opened up the Focal initrd.gz we use for PXE based installs (I think
it was from the mini.iso which I guess is now classified as a "Legacy

The Ubuntu Jammy installer initrd is missing the /etc/dhcp/dhclient-
exit-hooks.d/rfc3442-classless-routes hook for dhclient. The
/sbin/dhclient-script included in the initrd assumes the hook is present
and if the "rfc3442_classless_static_routes" DHCP is sent by the DHCP
server it ignores the the
Funny thing is that the rfc 3442 is from 2002.
Thats what makes me wonder of the missing support till today...
My workarround till today is to unzip the iso -> kernel+initrd, patch
the initrd, and use the patched initrd.
I would not recommend anyone to do it like that, only if theres no other

I just wanted to say that we are also hitting the same problem (lack of
dhcp option 121/249). So Subiquity connects to the network, but can't
get a default route and thus fails.
Couple this with the removal of debian-installer support from Ubuntu,
and we can no longer install Ubuntu Jammy LTS.
