open-iscsi upgrade fails to stop iscsid

[Bryan McLellan]

Binary package hint: open-iscsi

On an upgrade from open-iscsi=2.0.865-1ubuntu4 to open-iscsi=2.0.870.1-0ubuntu1, the postrm script for 2.0.865-1ubuntu4 stops iscsid via the initscript, which fails to to all iscsid processes. When apt then tries to run the postinstall script, the init script for open-iscsi fails to start due to the existing process.

Work around is to forcibly kill the iscsid processes before upgrade:

#306678 is a problem with the update-rc.d line triggered by an upgrade in the postinst script.

If this is a duplicate of anything, I think it's #181188, which resolves iscsid not stopping correctly. However the fix for this bug requires an upgrade and the upgrade path is not clean due to what I've reported in this bug.

This also breaks all PPA builds that depend on it:

Thank you for taking the time to report this bug. In an effort to keep an
up-to-date and valid list of bugs to work on, I have reviewed this report
to verify it still requires effort and occurs on an Ubuntu release in
standard support, and it does not.

It is unfortunate that we were unable to resolve this defect, however
there appears to be no further action possible at this time. I am
therefore moving the bug to 'Incomplete'. If you disagree or have
new information, we would be grateful if you could please add a comment
stating why and then change the status of the bug to 'New'.
