Hi,

You can fix this using sudo apt-get install scrot streamer mpg123
Then download the Ubuntu 20 prey installer from https://www.dropbox.com/s/glpb50o33yzhfvr/prey_1.9.4_u20_amd64.deb?dl=1
(sorry the dropbox link, I just created a custom installer for Ubuntu 20)

Then install it using this command sudo dpkg -i prey_1.9.4_u20_amd64.deb

Let me know how it goes
Regards,
Javo

@javo I came here to report the same error, but sorry, I'm not prepared to download and install a file from Dropbox provided by random Internet guy :)

Hi @darren12345, the fix is already available on the prey downloads site :)

@javo For Ubuntu 64-bit? Not when I happened to look earlier today.

Edit: Running sudo apt-get install --fix-broken fixed it!

I have just downloaded the software from the official site and installed in 3 different computers running Ubuntu 20.04 LTS. It worked flawlessly!

Thanks for supporting GNU/Linux!

[darren12345]

@KairanD was it is the 32 bit or 64 bit version?

[KairanD]

@darren12345 64 bit version.

[darren12345]

OK, I just noticed the update to @Vinnl 's post about running apt --fix-broken. This worked on two machines (it wanted to install about 90 extra packages though). However, on one I couldn't get it to open the Firefox URL for linking the machine to Prey. It's not a device I actually want to link though so I'm not too worried about that. It's working on my laptop now which is the main thing. Thanks all.
