All you have to do is run archey from terminal to get it to run...
Yes, having it there has an impact on .bashrc and I would remove it
Now, to solve this, I can add a startup function in Xfce to run
export PATH="$PATH:/sbin:/bin"
on login
One other thing I would like confirmed is whether or not this command is needed after one time being run.. Meaning does a shutdown and restart keep this
And it still makes no sense at all why adding something that is already there is needed to be added again
