rust-doc from -updates is uninstallable on 16.04 and 18.04

[Jan Claeys]

The package 'rust-doc' version '1.17.0+dfsg2-8~ubuntu0.17.04.1' in zesty-updates depends on the package 'fonts-open-sans', which doesn't exist in zesty.

This makes the package uninstallable and prevents upgrades.

Thanks for taking your time to report this issue and help making Ubuntu better.

I can confirm this issue on Ubuntu 17.04, both locally but also as listed on https://packages.ubuntu.com/zesty/rust-doc.

[Hans Joachim Desserud (hjd)]

Same issue is affecting 16.04 as well as 14.04 and I see that the latter is also lacking libjs-highlight.js https://packages.ubuntu.com/trusty/rust-doc. I suppose this was introduced when rustc was backported to older releases.

[Manfred Hampl (m-hampl)]

Why not just backporting fonts-open-sans to the older LTS releases?

[Olivier Tilloy (osomon)]

zesty has long been EOL, but xenial is still supported, and similarly affected.

[Simon Chopin (schopin)]

Closing this bug as fonts-open-sans is available in all supported distributions (Bionic and forward)
