Comment 13 for bug 223226

"What does the KDM-requires-restart-dialog say exactly?
When _exactly_ does it appear?"

Apologies for puttings this directly in the comment, but it seems sufficiently relevant and not excessively long. (Plus it's an extract of a log already attached to the report.)

Based on the logs, I have also now confirmed that my issue with 'kdm' *is* the same as the original submitter's issue.

As per the *very beginning* of the attached 'apt-term.log' (I've formatted it to remove the curses escapes, my 'apt-term.log' has the same):

Ubuntu Configuration
Configuring libc6

Running services and programs that are using NSS *need to be restarted*, otherwise they might not
be able to do lookup or authentication any more. The installation process is able to restart some
services (such as ssh or telnetd), but other programs cannot be restarted automatically. One such
program that *needs manual stopping and restart* after the glibc upgrade *by yourself* is xdm -
because automatic restart might disconnect your active X11 sessions.

This script detected the following installed services which *must* be stopped before the upgrade:
kdm

If you want to interrupt the upgrade now and continue later, please answer No to the question
below.

Do you want to upgrade glibc now?

<Yes> <No>

# *** Selected <No> to avoid the disconnecting active X11 sessions mentioned above. ***

*Stopped glibc upgrade. Please retry the upgrade after you have
checked or stopped services by hand.*

# (normal logging continued)"

Please note the time stamps of the last "Log ended" and "Log started" mentions. Between those 'kdm' was manually stopped, *as required* by the scripts started by running 'do-release-upgrade' with the appropriate options, and 'do-release-upgrade' then started for the second time.

The wording here (needs manual stopping by yourself etc.) is *significantly different* from the later "Please review the following space-separated list of init.d scripts for services to be restarted now, and correct it if needed" I quoted above as the "other" manual intervention ( https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/223226/comments/7 ).
