Ubuntu 16.04 - Gephi 0.9.1 não é possível executar

Question

A primeira vez que instalei o Gephi, tive alguns problemas, mas eles chegaram ao fim. Dois dias atrás, no entanto, ele decidiu parar de correr e não consigo localizar o problema. Eu tentei as soluções oferecidas em fóruns diferentes, mas nenhum deles resolveu. Ele basicamente trava durante a tela inicial.

    java version "1.8.0_131"
    Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Além disso, digite

    sudo apt-get update

retorna

Answer 1

Foi muito mais simples do que eu pensava:

    rm -r .gephi

e isso resolveu.
