Deleted libraries; need to boot in rescue mode (Fedora 20)
 

So when trying to update
Fedora 20, two similar libraries were found.
xz-libs-5.1.2-9alpha.fc20.x86_64
and
xz-libs-5.1.2-9alpha.fc20.i686
I believe they have to do with Skype package.
Update process couldn't continue.
It said there was a conflict with both versions.

Issue here is I attempted to remove the 64 bit version
Some other dependent libraires were shown and ask for confirmation before deletion. I confirmed.

Result is I cannot boot but in rescue mode and there is no sound.
When booting under updated distribution, system halts inevitably.

How can I restore the deleted libraries?
Do I have to reinstall the whole Fedora 20 version?

You could boot to a live CD and chroot into your system. Yum install while chrooted.
