As far as feeling like an idiot or a fool, I have been in the same position to many times. I shudder when I remember all the dumb things I have done…
I fact I made a big mistake earlier in the post where I showed you how to add new symlinks for libicu* .so files. I forgot to include the first step of removing the existing symlinks. I will update that post now with the added step. Apologies.
Convert to rolling means converting an existing OM Lx 4.2 system to Rolling from Konsole. A fresh install from an OM Lx Rolling iso is different. I thought we were trying to fix conversion attempt that went asunder. And it looked like we were close to fixing that. However if you can do a fresh installation that is preferred over a distribution upgrade always.
But to help I need to understand what you want to do.
This thread has instructions to do a distribution upgrade from OM Lx 4.2 to Rolling. It is a little complicated if user is not technically inclined.
If you want to do a fresh install of Rolling I recommend using this ISO.
