OK, I removed gnome-disk-utility-libs-2.30.1-2.el6.x86_64…
I had seen it in my logs but I thought it wasn’t critical to fix all broken dependencies and I was hoping it might get fixed in a later step of the upgrade…
(Nodejs I knew it needed to be removed and replaced so it was a no-brainer…)
It looks like the upgrade script doesn’t tolerate any broken dependencies in the list package it tries to update…
I removed it and now it went muuuuuch further…
As for DAHDI, I saw this in the script output now:
######### Updating Dahdi for this kernel #########
I do not know yet if it is working though…
I see it recompiled a few things, redownloaded modules and it’s now going through “repairs”…
######### Repairing PHP Version specific modules #########
######### Repairing areminder #########
######### Repairing broadcast #########
This is where it is right now…
I am keeping my fingers crossed hoping it will complete successfully… 
I will keep you posted…
Have a nice day!
