Não é possível instalar o Minecraft no Kubuntu 18.04

Question

Eu fiquei perplexo com esse problema de Java por cerca de 4 dias agora. Eu recentemente atualizei para o Kubuntu 18.04 e estou tentando fazer com que o Minecraft funcione sem sucesso. Aqui estão minhas mensagens de erro:

Eu tentei atualizar meus certificados, verifiquei que a porta 25565 está aberta, fez uma exceção para essa porta no UFW, embora eu tenha desabilitado, usei várias versões do OPENjdk e Oracle, usei diversas versões arquivadas diferentes do Minecraft.jar , tentei rodar como root (como você pode ver), mas não cheguei a lugar nenhum.

    

Answer 1

Eu também tive o mesmo problema e foi resolvido com o seguinte comando:

sudo snap install minecraft

Para iniciar o Minecraft, execute o seguinte comando:

minecraft

    

Answer 2

Para resolver o problema no kubuntu 18.04 eu fiz:

sudo rm /etc/ssl/certs/java/cacerts

e depois:

sudo update-ca-certificates -f

(não execute java com sudo )
