Following in the footsteps of Ubuntu Desktop, the Ubuntu Server official flavor won’t be shipping with 32-bit ISO images when the Ubuntu 18.04 LTS (Bionic Beaver) operating system will be released next year in April. Therefore, you won’t be able to install Ubuntu 18.04 LTS as a server, nor desktop OS on an old 32-bit computer. The removal of the 32-bit ISO images of the Ubuntu Server edition was discussed internally over at Canonical since early November, and there aren’t any 32-bit daily builds available to download on Canonical’s servers. However, today it was confirmed that Ubuntu 18.04 LTS would be a 64-bit release on both desktop and server.
