Using yum history. I already tried to undo a trans. Didn't work hence my post. It's also a CentOS7 system. I chose that os for some other things I have running on the headless system.

So now I'm sort of a rock and a hard place kind of deal. I remember when doing all these libraries initially so I could make my own QT I wanted to rip my hair out... really don't want to go through any more sleepless nights.

Is there something I can use in terminal to parse the yum log and spot out lib changes vs looking through an entire log for said changes ?

Also. What can / would I type to see current boost lib that's installed since the error references 1.57.0 ?
