package udev 229-4ubuntu4 failed to install/upgrade: /var/log/udev is a directory

Bug Description

upgrade to 16.04 failed


Test case: Install 15.10, remove the /var/log/udev file, and make it a directory (sudo mkdir -p /var/log/udev). Upgrade to 16.04 (at least udev). This will fail on this error with the xenial version, but should succeed with this fix.

Regression potential: practically zero. This only ignores errors on the rm of the old log file.

I have a workaround for this.

Since the error is "rm: cannot remove '/var/log/udev': Is a directory" what I did was to manually remove the folder

    sudo rm -r /var/log/udev
and then restart the configuration of the packages with

    sudo dpkg --configure -a

This led to a successfull upgrade to 16.04.

We don't really expect /var/log/udev to be a directory (nothing in Ubuntu creates it like that), but we should of course not fail the upgrade due to that. I committed a simple fix to .

This is only relevant for xenial, this transitional code will be dropped entirely in yakkety.

I launched a wily container, mkdir'ed /var/log/udev, installed udev from xenial and got the udev failure. I did the same procedure again, installed udev from xenial-proposed, and udev installed correctly.

This bug was fixed in the package systemd - 229-4ubuntu5

systemd (229-4ubuntu5) xenial-proposed; urgency=medium

  * debian/udev.postinst: Don't fail if /var/log/udev is a directory.
    (LP: #1574004)
  * Set MAC based name for USB network interfaces only for universally
    administered (i. e. stable) MACs, not for locally administered (i. e.
    randomly generated) ones. Drop /lib/systemd/network/
    (as link files don't currently support globs for MACAddress=) and replace
    with an udev rule in /lib/udev/rules.d/73-special-net-names.rules.
    (Closes: #812575, LP: #1574483)
  * debian/extra/init-functions.d/40-systemd: Invoke status command with
    --no-pager, to avoid blocking scripts that call an init.d script with
    "status" with an unexpected pager process. (Closes: #765175, LP: #1576409)
  * Add debian/extra/rules/70-debian-uaccess.rules: Make FIDO U2F dongles
    accessible to the user session. This avoids having to install libu2f-host0
    (which isn't discoverable at all) to make those devices work.
    (LP: #1387908)
  * On shutdown, unmount /tmp before disabling swap. (Closes: #788303)
