Ap\u00f3s dois anos desde o encerramento da forma\u00e7\u00e3o de imagens de instala\u00e7\u00e3o de 32 bits para a arquitetura x86, os desenvolvedores do Ubuntu tomaram a decis\u00e3o<\/a><\/noindex> de encerrar completamente o ciclo de vida dessa arquitetura na distribui\u00e7\u00e3o. A partir da vers\u00e3o de outono do Ubuntu 19.10, os pacotes no reposit\u00f3rio para a arquitetura i386 n\u00e3o ser\u00e3o mais gerados. <\/p>\n

O \u00faltimo lan\u00e7amento LTS para usu\u00e1rios de sistemas de 32 bits x86 ser\u00e1 o Ubuntu 18.04, cujo suporte se estender\u00e1 at\u00e9 abril de 2023 (com assinatura paga at\u00e9 2028). Todas as edi\u00e7\u00f5es oficiais do projeto (Xubuntu, Kubuntu, Lubuntu, etc.), assim como as distribui\u00e7\u00f5es derivadas (Linux Mint, Pop_OS, Zorin, etc.) n\u00e3o ter\u00e3o mais vers\u00f5es para a arquitetura de 32 bits x86, pois s\u00e3o constru\u00eddas a partir da base de pacotes do Ubuntu (a maioria das edi\u00e7\u00f5es j\u00e1 parou de fornecer imagens de instala\u00e7\u00e3o para i386).<\/p>\n

Para garantir a execu\u00e7\u00e3o de aplicativos existentes de 32 bits que n\u00e3o podem ser recompilados para sistemas de 64 bits (por exemplo, muitos jogos no Steam permanecem apenas nas compila\u00e7\u00f5es de 32 bits), em ambientes Ubuntu 19.10 e vers\u00f5es mais recentes \u00e9 oferecida<\/a><\/noindex> \u00e9 necess\u00e1rio usar um ambiente separado com o Ubuntu 18.04, instalado em um cont\u00eainer ou chroot, ou empacotar o aplicativo em um pacote snap com as bibliotecas de runtime core18 baseadas no Ubuntu 18.04.<\/p>\n

Como raz\u00e3o para a descontinua\u00e7\u00e3o do suporte \u00e0 arquitetura i386, menciona-se a impossibilidade de manter os pacotes ao n\u00edvel de outras arquiteturas suportadas no Ubuntu devido ao baixo n\u00edvel de suporte no n\u00facleo do Linux, ferramentas e navegadores. Em particular, os desenvolvimentos mais recentes em seguran\u00e7a e ferramentas de prote\u00e7\u00e3o contra vulnerabilidades fundamentais n\u00e3o s\u00e3o mais desenvolvidos de maneira oportuna para sistemas de 32 bits x86 e est\u00e3o dispon\u00edveis apenas para a arquitetura de 64 bits. <\/p>\n

Al\u00e9m disso, manter a base de pacotes para i386 requer muitos recursos de desenvolvimento e controle de qualidade, que n\u00e3o se justificam devido \u00e0 baixa base de usu\u00e1rios que ainda utiliza hardware desatualizado. O n\u00famero de sistemas i386 \u00e9 estimado em 1% do total de sistemas instalados. A maioria dos PCs e laptops com processadores Intel e AMD lan\u00e7ados nos \u00faltimos 10 anos pode ser facilmente migrada para o uso do modo de 64 bits. O hardware que n\u00e3o suporta o modo de 64 bits j\u00e1 est\u00e1 t\u00e3o desatualizado que n\u00e3o possui os recursos computacionais necess\u00e1rios para executar as vers\u00f5es mais recentes do Ubuntu Desktop.<\/p>\n
