Today i've started with Zesty system which was not used/updated since a week or so. Proposed is activated, so i've got the supposed fix: the upgrade still display an error related to the /var/apt/cache package, the upgrade failed. Need to purge the installed *xapian* packages before to be able to install apt-xapian-index
