Hi Kevin,
<div><br>
</div>
<div>Thanks for the stack trace that helps a lot. Walking through the code it seems there is a bug in the Software Collections rh-ruby22 package that you discovered. Although this bug exists, your installation of Open OnDemand should still work assuming:</div>
<div><br>
</div>
<div>- you restarted the per-user NGINX process after you changed all the home directories (try restarting your PUN, or the nuclear option restarting the whole machine)</div>
<div>- from the OnDemand host machine expanding the "~" gives the correct full path to your home directory<br>
<div><br>
</div>
<div>Could you confirm these?</div>
<div><br>
