I've verified that the contents of /usr/share/doc/libkrb5support0/changelog.Debian.gz in libkrb5support0 1.13.2+dfsg-5 correctly matches across architectures. This looks like a problem of local filesystem corruption on your install. You can check this by installing the debsums package and running 'debsums /usr/share/doc/libkrb5support0/changelog.Debian.gz', which should return no mismatches.

Also, the correct md5sum for this file is:

$ md5sum /usr/share/doc/libkrb5support0/changelog.Debian.gz
553513278beb9f1512774d100fbd3176 /usr/share/doc/libkrb5support0/changelog.Debian.gz
$

You should be able to resolve this problem either by running 'sudo apt install --reinstall libkrb5support0', or by manually removing /usr/share/doc/libkrb5support0/changelog.Debian.gz, and then installing libkrb5support0:i386.

Closing this as invalid, since this problem is not reproduced with the package in the Ubuntu archive.
