apt upgrade exits on error with slapd_2.4.21-0ubuntu5.5_amd64.deb

[datakid]

When I do either apt-get update; apt-get upgrade or aptitude upgrade, the process exits on error without completing fully.

The error is:

I tried running apport-collect as you suggested and I got this output:

datakid@thailand:~$ sudo apport-collect 844478
Package openldap not installed and no hook available, ignoring

No pending crash reports. Try --help for more information.

I tried another upgrade and apport-collect but got the same result?

cheers

I'm also concerned that this is given a low importance despite being a common piece of software on an LTS server release. Since it's "blocking" upgraes, which will be security upgrades, I would suggest that this is actually of higher importance.

This should be closed - I solved the problem by going around it, and can't reproduce it.
