[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.]

Some additional attempts to fix failed for me - I'm stuck and cannot
update or remove anything.

perl is already the newest version (5.26.0-8ubuntu1.1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libperl5.26 : Breaks: libperl5.26:i386 (!= 5.26.0-8ubuntu1) but 5.26.0-8ubuntu1.1 is to be installed
 libperl5.26:i386 : Breaks: libperl5.26 (!= 5.26.0-8ubuntu1.1) but 5.26.0-8ubuntu1 is to be installed
 perl : Depends: libperl5.26 (= 5.26.0-8ubuntu1.1) but 5.26.0-8ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
