pitti, please have a look, this seems to be related to systemd.
I hit this bug when using debootstrap+chroot (deboostrapping vivid to a new partition, then chrooting into the tree and then installing ubuntu-desktop): When the host system is an upstart system (14.10, fully updated), installing modemmanager works without problems, however if the host is the vivid livecd, then I hit this bug.

Relevant log bits:

Setting up modemmanager (1.4.0-1) ...^M
invoke-rc.d: unknown initscript, /etc/init.d/modemmanager not found.^M
dpkg: error processing package modemmanager (--configure):^M

Full log attached. apt-get was invoked the following way:

Just retested today. I have a bash script that debootstraps vivid, chroots into it and installs ubuntu-desktop.
From my utopic systeme everything is fine, but when the exact same script is run from the vivid live-cd, it fails with installing modemmanager.

Regarding chroot mounts:

 mount --bind /dev $target/dev
 mount --bind /dev/pts $target/dev/pts
 mount --bind /sys $target/sys
 mount --bind /proc $target/proc

This was apparently fixed in vivid's invoke-rc.d, i. e. considering the case that a package only has an upstart job and a systemd unit, but no init.d script. apt-get install modemmanager is fine in vivid, so this invoke-rc.d fix would need to get backported to utopic.

[Esokrates (esokrarkose)]

pitti, and how do you explain the strange behavior I observe with my deboostrap install method? NOTE: It works with the utopic host, but not with the vivid one.
As I workaround "touch /etc/init.d/modemmanager" works.

[Martin Pitt (pitti)]

Esokrates: When I do this in a chroot with a proper policy-rc.d (to suppress daemon starts, which is a must for doing things in a chroot), I get

Setting up modemmanager (1.4.0-1) ...
invoke-rc.d: unknown initscript, /etc/init.d/modemmanager not found.
invoke-rc.d: policy-rc.d denied execution of start.

and the package installs successfully. So it seems the "modemmanager not found" is a warning, but does not break stuff by itself. I guess what happens is that the postinst tries to actually start modemmanager in your chroot?

[Esokrates (esokrarkose)]

pitti, awesome as always, thanks, your explanation is right. The missing policy was the problem. Thanks very much!
