Bug#825421: libc6: Unable to upgrade

[Nicolas Patrois <nicolas.patrois@gmail.com>]

Package: libc6
Version: 2.22-7
Severity: normal

Dear Maintainer,

libc6 v. 2.22-7 can’t be upgraded to 2.22-9, the package is broken.
aptitude safe-upgrade libc6 keeps the package.
aptitude full-upgrade libc6 wants to remove libc6-i686 (OK, it’s a virtual package now) and upgrade several other libc6 packages but with no upgrade of libc6.
