[Secure-testing-team] Bug#833462: openjdk-7-jre-headless does not upgrade : does not find that /proc is mounted

[Erwan David]

Package: openjdk-7-jre-headless
Version: 7u111-2.6.7-1~deb8u1
Severity: important
Tags: security

When trying to upgrade openjdk-7-jre I get error :

Setting up openjdk-7-jre-headless:amd64 (7u111-2.6.7-1~deb8u1) ...
/var/lib/dpkg/info/openjdk-7-jre-headless:amd64.postinst: 19: /var/lib/dpkg/info/openjdk-7-jre-headless:amd64.postinst: mountpoint: not found
the java command requires a mounted proc fs (/proc).

Indeed I do not have the mountpoint command

Maybe a dependency needs to be restricted on the version number ?
