/etc/init.d/udev-finish does not get cleaned up on upgrade

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

The udev package in wily is missing /lib/udev/udev-finish, hence systemd reports the udev-finish.service as failed.
Placing this script , which is in udev package 219-7ubuntu6 (vivid-updates), into the correct location rectifies this.

udev-finish.service is gone, together with /lib/udev/udev-finish. That's quite deliberate, we don't need it any more.

Please give me the output of "sudo systemctl status -l udev-finish.service". Thanks!

Confirming that udev-finish.service is gone in udev 225-1ubuntu4 as compared to 219-7ubuntu6 (vivid-updates). Yet several files that should be removed (if I understand the udev package preinst/postinst/prerm/postrm scripts) aren't.. The output below is obtained after manually reinstalling the udev 225-7ubuntu6 deb via sudo dpkg -i

$ ls -l /etc/init | grep udev

-rwxr-xr-x 1 root root 6084 Jun 17 23:24 udev

Hope this helps ..

Can you please attach /etc/init.d/udev-finish? Did you perhaps modify this? This file is usually cleaned up on upgrade from versions earlier than 225-2.

[Martin Pitt (pitti)]

Ah well, it seems you downgraded to 219-7ubuntu6 again? If you upgrade to wily again with

  sudo apt-get install udev

can you please copy&paste the entire output?

No, I did not downgrade to 219-7ubuntu6. I manually downloaded that .deb file to compare it with 225-1ubuntu4. That was when I noticed that 219-7ubuntu6 had the /lib/udev/udev-finish script, which I copied over. I did restore a recent wily backup though, so these now obsolete udev files in /etc/init & /etc/init.d files might stem from that. I can confirm that these did not get removed when manually installing udev 225-1ubuntu4 though.

After manually removing /etc/init/udev-fallback-graphics.conf, /etc/init/udev-finish.conf & /etc/init.d/udev-finish and reinstalling udev 225-1ubuntu4 everything seems to be in perfect order again.

Might be one of those glitches, I can't be sure, but systemd no longer reports anything as failed and the system looks a ok :)

My apologies for the mixup, and many thanks for your kind and speedy replies!

Ah, this would explain it then.

I just did a dist-upgrade from vivid to current wily, and it works as intended:

Setting up udev (225-1ubuntu4) ...
Installing new version of config file /etc/init.d/udev ...
Installing new version of config file /etc/init/udevmonitor.conf ...
addgroup: The group `input' already exists as a system group. Exiting.
A chroot environment has been detected, udev not started.
update-initramfs: deferring update (trigger activated)
Removing obsolete conffile /etc/init.d/udev-finish ...
Removing obsolete conffile /etc/init/udev-finish.conf ...
Removing obsolete conffile /etc/init/udev-fallback-graphics.conf ...

And /etc/init.d/udev-finish is gone. So let's chalk this up as "your backup restored the file". (It's by far *not* a good idea to backup /etc/ in its entirety and restore it! Please just backup files that you actually changed).
