Bug#650346: doc-base trigger during perl upgrade leaves perl installation unusable

Tue Nov 29 01:19:47 UTC 2011

Package: perl
Version: 5.14.2-5
Severity: critical

When upgrading from 5.12 to 5.14.2-5, it is possible for doc-base
triggers to be run after unpacking perl, but prior to unpacking
perl-base or perl-modules, or the upgraded doc-base package. This
results in the apt installation job aborting (due to a failed trigger)
with a broken perl installation. The result looks a bit like this:

Press return to continue.

This situation can be recovered from by manually installing the new
versions of perl-base and perl-modules (with dpkg -i), then running
dpkg --configure -a.
