[Pkg-zsh-devel] Bug#976219: zsh uninstallable due to partial oldstable security update

[Anssi Kolehmainen]

Package: zsh                                                                              
Version: 5.3.1-4+deb9u4                                                                   
Severity: important

zsh just became uninstallable in oldstable (stretch) because security update 
is available for zsh-common but not for zsh.

apt install says
zsh : Depends: zsh-common (= 5.3.1-4) but 5.3.1-4+deb9u4 is to be installed

apt show says
Package: zsh
Version: 5.3.1-4+b3
Depends: zsh-common (= 5.3.1-4)

Package: zsh-common
Version: 5.3.1-4+deb9u4

(And thanks to fancy automated updates this actually caused removal of zsh in 
my systems)
