As you might have heard by now, Canonical has made the decision to drop 32bit support from Ubuntu 19.10 onwards.
Writing on the mailing list, as well as this post on Ubuntu's Community Hub, Canonical gave a reminder that the decision isn't coming without warning. It was proposed last year and it was followed up with another post detailing a final decision to be made in the middle of 2019. So here we are, the decision seems to have been made.
The problem isn't hardware, as likely around 99% of people nowadays have a 64bit capable computer. Going by our own statistics, from what 2,254 users told us only 4 are using a 32bit Linux distribution. The issue then, is mainly software and libraries needed to actually run 32bit applications. This is where it sounds like there's going to be plenty of teething issues, with a number of people not too happy about the decision.
Steam, for example, is one such application along with plenty of 32bit games that will likely never get updated, although Canonical did say they're "in discussions" with Valve about it. There's also GOG, Humble Store and itch.io which all provide a number of direct-download 32bit games, which do not supply the required 32bit libraries to run. It doesn't sound like they have been given any thought (at least they haven't been mentioned).
Another of the major problems being Wine, with a discussion now happening on their mailing list. The discussion doesn't seem to be too positive, with developer Henri Verbeet even saying "I think not building packages for Ubuntu 19.10 would be the only practical option.", although Andrew Eikum's idea of using the Steam Runtime could be an interesting way around it.
What are your thoughts?
