[Bug 1577460] Re: mkinitramfs --help > Core dumped

[Dimitri John Ledkov]

"With Ubuntu 14.40 login via ssh:" doesn't make sense at all =) There is
no such thing as 14.40 release of Ubuntu. Sounds like miss-typed 14.04,
however 14.04 doesn't exist for s390x, and the bug report is for s390x.
So we guess it's for 16.04. But that's mostly irrelevant misleading
details.

The bug is valid, and reproducible on other architectures. This is not
s390x specific.

Running locale-gen and/or installer relevant langpacks (e.g. german
langpack) but getopt really should not segfault like that, as it's
common for user to have locales, that are not available on the target
server.
