Installing Screaming Frog (.deb package) on WSL

I am running a Windows 10 computer with Ubuntu 18.04 running via the Windows Subsystem for Linux.

I am trying to install an SEO spider, Screaming Frog, so that I can run it in headless mode and run crawls programmatically. It appears to have been installed correctly, but when I try to run it on the command line with screamingfrogseospider, the following error is thrown:

/usr/bin/screamingfrogseospider: line 18: /usr/share/screamingfrogseospider/jre/bin//java: No such file or directory 

Does anyone have any ideas why this could be occuring?

Installing .deb package using gdebi

I’m having some problems installing .deb packages on my laptop running Ubuntu 18.10
I’m completely new to Linux coming from Windows so sometimes you’ll have to explain stuff to me like I’m five

First I downloaded some .deb packages via Firefox, then I just double clicked one and the Ubuntu Software Center started.
I pressed ‘Install’, it then asked me for my password which I entered.
At first it would just go back to the Install button, but now after trying a lot of Terminal commands it just shows a progress bar which stays at 0%.

Like I said I tried a lot of commands that I found after some Googling. I also tried installing Gdebi but that resulted in following Error which I couldn’t resolve with Googling:

dirk@Ubuntu-L:~$   sudo apt-get install gdebi [sudo] password for dirk:  Reading package lists... Done Building dependency tree        Reading state information... Done You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies:  discord : Depends: libatomic1 but it is not going to be installed            Depends: libgconf-2-4 but it is not going to be installed            Depends: libappindicator1 but it is not going to be installed            Depends: libc++1  gdebi : Depends: gdebi-core (= but it is not going to be installed          Depends: gnome-icon-theme but it is not going to be installed          Recommends: libgtk2-perl but it is not going to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). 

Basically I need help installing .deb packages. The “normal” Ubuntu doesn’t seem to work which I found is a common problem with the solution to use Gdebi. But Gdebi also doesn’t seem to work for me.
Currently I’m quite close to just re-installing my whole Ubuntu system and hoping it works then. Or just going back to Windows which I luckily still have in a multi-boot.
