[Bug 520021] [NEW] update-initramfs fails due to loss of /lib/udev/firmware.sh during update

[Peter Belew]

Public bug reported:

Binary package hint: initramfs-tools

Serious problem during apt-get dist-upgrade after apt-get update:

The file /lib/udev/firmware.sh is apparently deleted during some part of
an update. This file is essential to update-initramfs. It is almost
impossible to continue any updates or installs to the system after this
file has been lost.

This happened on 2 systems this morning (see below about that).

Is this bug in initramfs-tools, possibly?

About 10 am PST on 2010-02-10

last few lines of screen output from 'apt-get dist-upgrade'

And then ...

# apt-get dist-upgrade
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 

So then I try dpkg:

# dpkg --configure -a

The locate command thinks that the script is still there:

# locate firmware.sh
/lib/udev/firmware.sh

But it isn't:

# ls /lib/udev | grep firmware
firmware

This has happened on two systems this morning. It made it really
impossible to update the system! Fortunately, since I have two systems,
it was possible to copy the script from the other system, and to
continue the update.

After copying the file, I could complete the installation:

dpkg --configure -a
root at lightning:/lib/udev# !dpkg
dpkg --configure -a
