Não é possível instalar o GitKraken

Acabei de instalar o GitKraken (A Git GUI) baixando-o do site. Quando tento instalá-lo via 'Discover Center', ele não funciona. Então encontrei em algum lugar online o comando dpkg -i [filename], usei-o no gitkraken .deb e noddd MAGIC! Funciona!

Eu tentei executar o GitKraken (digitando no gitkrakenterminal), e isso me deu esse erro bonito:

Qualquer ajuda seria muito apreciada.

Em terminal...

• sudo apt-get update
• sudo apt-get install curl libcurl3

Agora seu aplicativo deve funcionar.

Instalei o libgnome-keyring-common e o libgnome-keyring-dev no ubuntu 16.04, que resolveu o problema para mim:

sudo apt install libgnome-keyring-common libgnome-keyring-dev 

Eu usei o seguinte comando:

$ sudo apt-get install curl libcurl3 

e obteve o erro abaixo:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 curl : Depends: libcurl4 (= 7.58.0-2ubuntu3.8) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Então mudei meu comando para:

$ sudo apt-get install curl libcurl4

E lembre-se sempre de atualizar os pacotes antes, como mostra Heynnema!
