Eu tenho o mesmo problema ao usar wubi1510r298.exefromhttps://www.dropbox.com/sh/6uqomp8l1frcd1y/AAAhSCimTaYE-94egbmc1X_na?dl=0, em dois computadores diferentes.

Também tenho o mesmo problema ao tentar instalar o Ubuntu em vez do Kubuntu.

Answer 1

O algoritmo hash para assinaturas gpg mudou de sha1 para sha512 e sha512 não é suportado pelo módulo Wubi usado.

Eu carreguei um patch paralaunchpad.net(Código fonte)

O patch ainda não oferece suporte ao sha512, mas oferece um melhor tratamento de erros. Então ele grava as seguintes mensagens no log ...

WARNING saplog: A signature from ID:'46181433FBB75451' has an unsupported hash algorithm:10(SHA512).
ERROR  CommonBackend: Could not verify signature for metalink md5sums
ERROR  CommonBackend: Cannot authenticate the metalink file, it might be corrupt

... mas não há nenhum erro fatal não tratado que impeça a instalação.

Se você deseja corrigir um wubi.exe existente, não é necessário compilar todo o wubi.exe a partir da fonte.

Se você copiar api.py da fonte (caminho de origem:/src/openpgp/sap/api.py) para seu wubi.exe com 7z (caminho de destino:/lib/openpgp/sap/api.py) também deve funcionar.

Se você não quiser corrigir nada,aquitambém já são versões corrigidas.wubi14043.exe,wubi14043SB.exeewubi1504SB.exeuse um api.py adicional.wubi1510r299.exeusa uma nova compilação da fonte.

Answer 2

Consegui contornar esse problema com o Ubuntu 14.04.3 (funciona 100%). Você pode tentar executar o mesmo método no Kubuntu 14.04.3 (deve funcionar) ou analisar o arquivo isolist.ini alterado (verifique os comentários) e atualizar wubi1510r298.exe de acordo para executar a versão mais recente.

Aqui está a instrução (para a versão 14.04.3):

1. Downloadkubuntu-14.04.3-desktop-i386.isoem um diretório separado.
2. Downloadwubi14043.exe(para a versão 14.04.3) no mesmo diretório.
3. Instale 7z.

4. No diretório com wubi14043.exe crie uma pasta temporária:

   mkdir wubi-temp

5. Vá para a pasta temporária:

   cd wubi-temp

6. Extraia wubi14043.exe para a pasta tmp:

   7z x ../wubi14043.exe

7. Edite o arquivo data/isolist.ini e substitua seu conteúdo pelo conteúdo que colei abaixo.

8. Atualize seu wubi14043.exe com isolist.ini alterado:

   7z você ../wubi14043.exe

9. Remover pasta temporária:

   cd..
   rd /s wubi-temp

10. Desconecte seu computador da rede e execute wubi14043.exe atualizado - ele deve ser capaz de instalar o Kubuntu a partir do ISO local agora.
