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. ** Changed in: krb5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652549 Title: package libkrb5support0 1.13.2+dfsg-5 failed to install/upgrade: trying to overwrite shared '/usr/share/doc/libkrb5support0/changelog.Debian.gz', which is different from other instances of package libkrb5support0:i386 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1652549/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
