Subject: libruby2.7: ENOENT error crash some ruby scripts

Date: Fri, 28 Aug 2020 02:23:37 +0200

Package: libruby2.7
Version: 2.7.1-3
Severity: important
X-Debbugs-Cc: antoni@friki.cat

Dear Maintainer,

Some ruby scripts fail to run from a removed directory.

If apt-listchanges package is installed apt crashes that way. That's why I've
switched to "important".

Following inline patch fixes the issue.
