I just did a wheezy-to-jessie dist-upgrade of my system and the process aborted twice (after dpkg is set upped): Setting up dpkg (1.17.21) ... <lot of messages> dpkg: cycle found while processing triggers: chain of packages whose triggers are or may be responsible: doc-base -> doc-base packages' pending triggers which are or may be unresolvable: doc-base: /usr/share/doc-base dpkg: error processing package doc-base (--configure): triggers looping, abandoned and after apt-get install -f and apt-get dist-upgrade again: dpkg: cycle found while processing triggers: chain of packages whose triggers are or may be responsible: man-db -> man-db packages' pending triggers which are or may be unresolvable: man-db: /usr/share/man dpkg: error processing package man-db (--configure): triggers looping, abandoned If it helps, I can provide a (script) log of the upgrade process.
