[Pkg-javascript-devel] Bug#944821: Unhandled (and undocumented) directory to symlink (and vice versa) change breaks on upgrade

[David Prévot]

Source: popper.js
Version: 1.14.6+ds2-2
Severity: serious

The /usr/share/javascript/popper.js proper directory became a symlink in
the latest version, but dpkg does not support it, and it wasn’t handled
in maintainer scripts (nor documented in d/changelog).

Upgrading from 1.14.6+ds2-2 to 1.14.6+ds2-1 ends up with an empty
directory.

dpkg-maintscript-helper(1) should be helpful.

Regards

David
