python3-xapian not installed when apt-xapian-index upgraded

While apt-xapian-index gained a depends on python3-xapian, python3-xapian1.3 also provides that package so during an upgrade python3-xapian1.3 is kept and python3-xapian is not installed. If the dependency for apt-xapian-index is made a versioned one then python3-xapian will get installed.

The apt-xapian-index change is insufficient as python3-xapian1.3 wasn't removed first.

Is there a workaround for this bug? On my system apt has stopped working altogether because of this broken pipe error.

Look like it's fixed.

Yesterday I purged both "python3-xapian" and "apt-xapian-index".

Few minutes ago i reinstalled apt-xapian-index and python3-xapian via synaptic, it worked with no issues being reported.

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

Since a week or so isn't really enough information for me to determine
what packages you had installed before the upgrade. Please include the
specific package versions (apt-xapian-index, python3-xapian,
python3-xapian1.3) you had installed.

What command did you use to upgrade? What was the exact error message
you received?

I appreciate the time you are taking to perform testing but we really
need more information for it to be actionable.
