Re: Bug#976219: zsh uninstallable due to partial oldstable security update
zsh package has appeared in security.debian.org and now it is installable again.
Some timestamps in http://security.debian.org/debian-security/pool/updates/main/z/zsh/
zsh-common_5.3.1-4+deb9u4_all.deb 2020-12-01 04:13
zsh_5.3.1-4+deb9u4.dsc 2020-12-01 03:53
zsh_5.3.1-4+deb9u4_amd64.deb 2020-12-01 04:28
Yesterday when I made this ticket amd64.deb was not there.
arch:all was built on 2020-12-01 04:09:37
arch:amd64 was built on 2020-12-01 04:10:40
I wonder was this upload made just at the same time as FTP update was running
and then only zsh-common was available at that moment.
