Another Ubuntu upgrade; minor bugfix deployed

Team blog: Developers

The VPS is now running on Ubuntu 20.04 (Focal), the latest Long Term Support release, which receives security updates until April 2025. The upgrade was fairly painless, but the do-release-upgrade wrapper script was interrupted, and I had to manually fix some broken packages.

I also fixed a small bug which has been annoying me for a while: The Wikidata search box wasn’t working when you started a new review, until you un-focused and re-focused it.
