Welcome to LQ.
? Which (Mint?) OS is it you want to install ``audacity`` into ?
Please show the outputs from these two commands :
Code:
a) uname -m
b) cat /etc/issue
Audacity has some (many) dependencies you will have to download too :
http://packages.ubuntu.com/trusty/audacity
libc6, libexpat1, libgcc1, libglib2.0-0, libgtk2.0-0 you already have.
What you need, is an audacity version that requires some available sound-codecs etc.
( A random ppa version may not be the right choice.)
