cannot upgrade or remove multipath-tools

[John Magolske]

In doing `aptitude ugrade`, multipath-tools is to be upgraded, but I
keep getting the following message:

% sudo aptitude install multipath-tools
[...]

Nor can I purge the package:

Thanks for any help sorting this out,

Could it be because of this?

Yes, I was looking at that last night after emailing the list:

If a user's setup is direct access to scsi device, be it either sd
naming scheme or persistent names, it appears that no entry for it
is created in /sys/block sysfs hierarchy.

In this scenario, the multipath-tools' stop target fails thusly
breaking all upgrades.

Current resolution is to run the init script to survive errors,
i.e. "!sh -e"

I tried what I think is being suggested here, changing the first
line of /etc/init.d/multipath-tools to "#!/bin/sh -e", but still get
"...package failed to install" when trying to upgrade multipath-tools,
and this when running "multipath-tools stop" manually:

# /etc/init.d/multipath-tools stop

Device does not exist.
Command failed

I did notice however this morning that `aptitude upgrade` does not try
to upgrade multipath-tools. A dist-upgrade does still want to upgrade
this package -- as did a regular upgrade as recently as yesterday. But
now for some reason I can do a regular upgrade without the complaining
brought on by multipath-tools.

After editing the boot script I guess the service should be restarted
again to reflect the changes so that when it's stopped it does not fail.

You can try "dist-upgrading" again once you have edited the init script
and daemon has been restarted. Or you can also take a more practical
approach and manually download the updated deb package (0.4.9
+git0.4dfdaf2b-6) and copy/paste the init script or look for the
differences :-)

Thanks for the helpful suggestions, here's what solved the problem:

% cp /var/cache/apt/archives/multipath-tools_0.4.9+git0.4dfdaf2b-6_i386.deb /tmp
% cd /tmp
% aunpack multipath-tools_0.4.9+git0.4dfdaf2b-6_i386.deb
# mv /etc/init.d/multipath-tools /etc/init.d/multipath-tools-1
# cd /tmp/multipath-tools_0.4.9+git0.4dfdaf2b-6_i386
# cp etc/init.d/multipath-tools /etc/init.d/multipath-tools
# /etc/init.d/multipath-tools restart
# rm /etc/init.d/multipath-tools-1

After restarting the multipath-tools daemon, I was able to upgrade the
multipath-tools package successfully.

Thanks again!

John
