Ubuntu's Canonical engineers and community members work together to determine their 32-bit support adjustments to the Ubuntu 20.04 LTS version.
After giving up the initial proposal (ie eliminate 32 packages), Ubuntu 19.10 comes with a reduced set of 32 packages (32-bit x86), available for x86_64 users. Those 32-bit packages on Ubuntu 19.10 were selected based on popularity, they may still widely used on modern Intel / AMD systems. For Ubuntu 20.04 LTS, undergoing some small adjustments.
Ubuntu community of this post lists some adding and removing programs conducted on Ubuntu 20.04 LTS. And libssl 1.0, like, wine-stable-i386, gcc -8-base and other software packages, as obsolete or other factors are removed. At the same time also added other 32 packages, including Freeglut, libv4l, VDPAU driver, VA-API driver and a variety of other libraries.
Ubuntu developer Steve Langasek outlines around 1,700 source packages will trigger a build Ubuntu Focal (20.04) in the Launchpad on the i386. Upcoming are a number of other changes to build infrastructure, and improvement / automatic packaging of its test infrastructure.
Overall, Ubuntu 20.04 LTS 32-bit support package will be very similar to the way to use Steam in Ubuntu 19.10, and still have access to other software packages not yet fully belong to the x86_64.
