If I re-enable armel and proceed with removal (a newer libc6:amd64 had
already been installed causing breakage, see Bug#670668), I get a
cryptic error from dpkg, but can't be sure who's causing it - at least
things seem back in working order as far as packages seem concerned:
(Reading database ... 438877 files and directories currently installed.)
Removing libgcc1:armel ...
dpkg: libc6:armel: dependency problems, but removing anyway as you requested:
locales depends on glibc-2.13-1; however:
Package glibc-2.13-1 is not installed.
Package libc6:armel which provides glibc-2.13-1 is to be removed.
Package libc6:amd64 which provides glibc-2.13-1 is not configured yet.
Removing libc6:armel ...
dpkg: error: --configure needs a valid package name but 'libc6' is not: ambiguous package name 'libc6' with more than one installed instance
Type dpkg --help for help about installing and deinstalling packages [*];
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Options marked [*] produce a lot of output - pipe it through `less' or `more' !
E: Sub-process /usr/bin/dpkg returned an error code (2)
