Eu tentei a solução de este link Mas não obtendo solução

Eu tentei instalar GRASS GIS, OSGeo, etc

    

Answer 1

1. Entre no /etc/apt/sources.list.d e procure por moka-ubuntu-daily-xenial.list e exclua-o se houver mais de uma entrada.
2. Execute também o passo seguinte para noobslab-ubuntu-apps-dependencies-xenial.list .
3. Onde as linhas estão começando com E , isso significa erro. verifique se o URL está correto ou não.
4. Para todas as linhas com W , elas são um aviso. De acordo com os registros, podemos concluir que a URL que você colocou não está acessível.

Answer 2

Primeiro

Para o erro configured multiple times , em terminal , faça o seguinte:

ls -al /etc/apt/sources.list.d/moka-ubuntu-daily-xenial.list*

Você provavelmente verá isso:

moka-ubuntu-daily-xenial.list
moka-ubuntu-daily-xenial.list:2
moka-ubuntu-daily-xenial.list:3
moka-ubuntu-daily-xenial.list:4

Deixe moka-ubuntu-daily-xenial.list sozinho e exclua os 3 restantes com:

sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:2
sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:3
sudo rm /etc/apt/source.list.d/moka-ubuntu-daily-xenial.list:4

Segunda

Para os erros 404 Not Found , veja minha resposta anterior a essa mesma pergunta em como redefinir as fontes de atualização

Terceiro

Ignore os erros do SHA1.

Quarto

Para os erros repository can't be authenticated , instale y-ppa-manager e atualize as chaves de autorização gpg. Em terminal , digite:

sudo apt-get update
sudo apt-get install y-ppa-manager

Em seguida, inicie PPA Manager no painel do Unity.
