A Canonical publicou<\/a><\/noindex> Declara\u00e7\u00e3o sobre a revis\u00e3o dos planos relacionados \u00e0 descontinua\u00e7\u00e3o do suporte \u00e0 arquitetura de 32 bits x86 no Ubuntu 19.10. Ap\u00f3s considerar os coment\u00e1rios, expresso<\/a><\/noindex> pelos desenvolvedores do Wine e plataformas de jogos, foi decidido garantir a constru\u00e7\u00e3o e fornecimento de um conjunto separado de pacotes de 32 bits no Ubuntu 19.10 e 20.04 LTS.<\/p>\n

A lista de pacotes de 32 bits fornecidos ser\u00e1 elaborada levando em conta os desejos da comunidade e incluir\u00e1 componentes necess\u00e1rios para a continuidade da opera\u00e7\u00e3o de programas legados que permanecem apenas na vers\u00e3o de 32 bits ou que requerem bibliotecas de 32 bits. Caso a lista se mostre incompleta e pacotes ausentes sejam identificados, o conjunto de pacotes ser\u00e1 ampliado mesmo ap\u00f3s o lan\u00e7amento.<\/p>\n

Afirma-se que as discuss\u00f5es e coment\u00e1rios surgidos ap\u00f3s o an\u00fancio da descontinua\u00e7\u00e3o do suporte \u00e0 arquitetura i386 foram uma surpresa para os desenvolvedores da distribui\u00e7\u00e3o, uma vez que a quest\u00e3o da descontinua\u00e7\u00e3o do suporte \u00e0 i386 tem sido discutida na comunidade e entre os desenvolvedores desde 2014. Os desenvolvedores do Ubuntu tiveram a impress\u00e3o de que havia consenso sobre a quest\u00e3o da descontinua\u00e7\u00e3o do suporte \u00e0 i386 e que n\u00e3o haveria surpresas, mas aparentemente alguns pontos foram negligenciados, incluindo durante consultas com a Valve (nota: \u00e9 poss\u00edvel que alguns dos discutindo n\u00e3o tivessem a expectativa de que seria decidido n\u00e3o apenas interromper a constru\u00e7\u00e3o de pacotes i386, mas tamb\u00e9m abrir m\u00e3o da forma\u00e7\u00e3o de bibliotecas multiarch, necess\u00e1rias para executar aplicativos de 32 bits em um ambiente de 64 bits).<\/p>\n

A longo prazo, para garantir o suporte a aplicativos de 32 bits em lan\u00e7amentos ap\u00f3s o Ubuntu 20.04, planeja-se desenvolver em conjunto com WINE, Ubuntu Studio e fornecedores de jogos uma solu\u00e7\u00e3o para o uso de sistemas de containeriza\u00e7\u00e3o para fornecer componentes de 32 bits da ramifica\u00e7\u00e3o LTS do Ubuntu e organizar a execu\u00e7\u00e3o de aplicativos antigos. Com base em Snaps e LXD, ser\u00e1 poss\u00edvel preparar o ambiente necess\u00e1rio de 32 bits e o conjunto de bibliotecas.<\/p>\n

Lembramos que a raz\u00e3o para a interrup\u00e7\u00e3o do suporte \u00e0 arquitetura i386 \u00e9 a impossibilidade de manter os pacotes no mesmo n\u00edvel das outras arquiteturas suportadas no Ubuntu, por exemplo, devido \u00e0 indisponibilidade das \u00faltimas inova\u00e7\u00f5es em seguran\u00e7a e prote\u00e7\u00e3o contra vulnerabilidades fundamentais como Spectre para sistemas de 32 bits. Manter a base de pacotes para i386 requer muitos recursos em desenvolvimento e controle de qualidade, o que n\u00e3o se justifica devido \u00e0 base de usu\u00e1rios reduzida (o n\u00famero de sistemas i386 \u00e9 estimado em 1% do total de sistemas instalados).<\/p>\n
