[Bug 1773152] [NEW] Error updating xubuntu 18.04 LTS bionic. Cannot overwrite libperl5.26:i386

[Mark Beardsley]

Public bug reported:

Whenever I try to update my system, the following error message is
reported;

E: /var/cache/apt/archives/libperl5.26_5.26.1-6_i386.deb: trying to
overwrite shared '/usr/share/doc/libperl5.26/changelog.Debian.gz', which
is different from other instances of package libperl5.26:i386

The error survives any attempt I make to fix broken packages as advised
if I try to perform and apt-get update operation in a terminal window.
The text of the pasted into the window above was displayed in a pop-up
window when using Synaptic Package Manager to perform an update of the
system.

Below is the full text displayed in the 'Details' section of the package
manager;
