Canonical announced shortly after the release of Ubuntu 23.10 that the official downloads were pulled, as there was hate speech identified from a malicious contributor in some of their translations.
They posted the announcement on X, with a link to their Discourse post that gave a bit more info. In the post they mentioned it affected a "specific set of translations of the Ubuntu Desktop installer UI" and so they've taken immediate action to sort the situation with the translations being removed and replaced.
Affected downloads were for Ubuntu Desktop 23.10, Ubuntu Budgie 23.10 and the Ubuntu Desktop daily images.
Since it's all open source on GitHub, we can go in and check what actually happened. Specifically, the Ukrainian translation has been entirely removed for now and it doesn't really take a lot of thought as to why. I translated a bit of it that I won't repeat here and…yeah. No surprise it has been pulled, it was bad.
Completely ridiculous that someone would target a Linux distribution like this.
