Linux tarball install script broken on Kubuntu 25.10

[Petrosophia]

There is an install script on this page online/this file in the repo.

I wound up needing to

1. copy and paste the install.sh file manually from GitHub (put it into a file called zen-install.sh)
2. edit it (see below)
3. chmod +x zen-install.sh
4. ./zen-install.sh

in order to install it correctly.

For some reason, line 54 of install.sh wasn't working for me. Currently, it reads:

tar -xvJf $tar_location

I had to change it to

tar -xf $tar_location

to make it run without error. I probably could have left the -v flag, but -J was giving me problems, even though it should have been fine for a .tar.xz file.

EDIT: I forgot to mention, I'm running Kubuntu 25.10.
