Install failed on fresh Ubuntu 22.04 LTS

[ColinAF]

I tired to install this on a fresh install of Ubuntu 22.04 LTS and I got a few errors. It seemed like dconf was complaining about extra slashes in the profile_path. I was able to fix this by using sed to chop off any trailing slashes. I'm not much of a bash guy so I'm not sure if this is ideal but it allowed me to install the theme. Additionally I was seeing "error: Failed to execute child process “dbus-launch” (No such file or directory)" pop up a couple times during the install and I was able to resolve this by installing dbus-x11. This was not listed in the INSTALL.md. I went ahead and made these changes and am submitting a pull request.
