Estou trabalhando com um programa do governo que foi escrito em Fortran 77 e requer o g77 para configurar e compilar o código-fonte. Eu entendo que o g77 foi extinto e substituído por compiladores mais novos, mas meu ponto de contato com o governo e eu estamos descobrindo que os compiladores mais novos no GCC produzem inúmeros erros quando tentamos compilar este programa.
Eu tentei instruções que estavam disponíveis em uma pergunta postada anteriormente para o Ubuntu 12, onde o arquivo sources.list é emendado para adicionar as páginas do Hardy Ubuntu, e então deve estar disponível. No entanto, como mostra a saída abaixo, isso não foi bem-sucedido. Eu tentei procurar por outras fontes do g77, mas nada apareceu.
Eu tentei instalar versões anteriores do Linux neste computador e em outros, apenas para descobrir que as versões que baixei estavam com falta dos principais recursos e não puderam ser instaladas. Por favor, dê uma resposta detalhada, pois não tenho muita experiência com o Linux.
