Well you are correct. It looks like sldap is the reason for your problem proceeding.
Errors were encountered while processing: /var/cache/apt/archives/slapd_2.4.28-1.1ubuntu3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I would suggest filing a bug against that package. This report is rather large now so it would not be the best for me to change packages at this point. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/943638 Title: upgrade lucid to precise has missing candidates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/943638/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
