Can't open key archive

[jhoc2000]

I'm trying to import my Kontalk account onto my Linux computer. I've downloaded and extracted the zip desktop zip file: KontalkDesktop-3.1.2.zip
I then change into the directory: KontalkDesktop-3.1.2
and try to run the Java file: ./KontalkDesktopApp.jar

The GUI appears but I get the Java output:

The import wizard is show and I select next:
I enter the Kontalk_keys.zip file that I exported from my phone and the password and select next. I then get the error: Can't open key archive even though the pathname and file name are correct. The permissions on the file are: -rwxrwx-wx

Additional information

Operating System: Ubuntu 19.04
Desktop Environment: Mate 1.20.4
Kontalk Android version: 4.3.1

(For errors please check for exceptions or warnings in the log file and
include them here. More information: https://github.com/kontalk/desktopclient-java/wiki#i-found-a-bug-what-to-do )

Where's the log file so that I can provide any errors?

Thanks for reporting. What version of Java are you using? For the moment the client has been tested on Java 8 only (it should work on 9 too in theory, but not 11 or 12).
