Is the new Ubuntu 21.10 compatible with 32-bit (for termux)? [closed]

I recently received a 64-bit version of new Ubuntu daily builds. You can download Ubuntu 21.10 daily builds from the Ubuntu website. You will be able to download Ubuntu 21.10 on October 14, 2021. This date is the one listed on Launchpad, the home of Ubuntu development.

Does the new version of Ubuntu (21.10) have a 32-bit version, which can be installed on Android phones within Termux?

You may be looking for 32bit ARM, i.e. the armhf architecture, which Ubuntu 21.10 does support.

However, Ubuntu does not anymore support the traditional 32bit (i386) architecture, as Thomas Ward mentioned in the other answer.

32-bit ARM

ARM 32bit is supported by all current releases (and currently, all future releases) of Ubuntu, and can be installed in Termux once their system catches up with cloud releases.

However, this is limited to devices with the armhf infrastructure instruction set specifically - it will not work for older armel devices or devices that don't speak armhf in the right endianness.

32-bit non-ARM

There are no Ubuntu versions that support standard 32-bit. This includes all current and all FUTURE Ubuntu versions.

The last supported version of Ubuntu that was 32bit was (only just barely) Ubuntu 18.04. Since 18.04, there are no 32bit ISOs/images anymore.
