Answer 1

Você pode instalar os seguintes pacotes

• libjavascriptcoregtk-1.0-0 (2.4.8-1ubuntu)
• libjavascriptcoregtk-3.0-0 (2.4.8-1ubuntu2)
• libjavascriptcoregtk-4.0-18 (2.6.2+dfsg1-4ubuntu1)

mas não libjavascriptcoregtk-2.4.9-0 .

E você tinha o PPA ppa:webkit-team no seu sistema antes e, portanto, libjavascriptcoregtk-3.0-0 (2.4.9-0ubuntu1~15.04~webkitteam1) instalado. Se você precisar do PPA (de novo) pule no final da minha resposta e ignore os próximos passos.

O problema é que libwebkit2gtk-3.0-25 dos Repositórios Padrão do Ubuntu precisa exatamente de libjavascriptcoregtk-3.0-0 (2.4.8-1ubuntu2) .

A solução mais rápida é o downgrade do pacote libjavascriptcoregtk-3.0-0 via

sudo apt-get install libjavascriptcoregtk-3.0-0=2.4.8-1ubuntu2

mas você deve usar os comandos abaixo para fazer o downgrade de todos os pacotes, atualizados pelo PPA ppa:webkit-team

sudo apt-get install ppa-purge
sudo apt-add-repository ppa:webkit-team
sudo apt-get update
sudo ppa-purge ppa:webkit-team

No futuro, use ppa-purge para remover um PPA do seu sistema.

Se você precisar do PPA, adicione-o novamente e use-o, e seu problema também será resolvido

sudo apt-add-repository ppa:webkit-team
sudo apt-get update
sudo apt-get dist-upgrade
