[Bug 1764614] Re: package libperl5.26 5.26.0-8ubuntu1 [modified: usr/share/doc/libperl5.26/changelog.Debian.gz] failed to install/upgrade: trying to overwrite shared '/usr/share/doc/libperl5.26/changelog.Debian.gz', which is different from other instances of package libperl5.26:amd64

[Mike B.]

Found a FIX! Just need to move/backup the shared doc file that was
causing the problem and all is right again.

~| sudo mv /usr/share/doc/libperl5.26 /usr/share/doc/libperl5.26.barron
~| sudo apt --fix-broken install
