Install script is not working anymore

Tried to install octodash with the script provided in the wiki. It gave some errors, so I tried manually.
errors in script

All is going well until I want to install

sudo apt install xserver-xorg ratpoison x11-xserver-utils xinit libgtk-3-0
then I get the same errors.

Where can I get the files needed for the install?

Thanks in advance
