I was unable to install wine on Pear Linux 7 without any clues to solve it. As an alternative, I install PlayOnLinux on my Pear Linux 7 and it works pretty well. I can install my Metatrader 4 (Windows app) on Pear Linux 7 smoothly. This tutorial will show you how to install PlayOnLinux on Pear Linux 7. This can be applied to another Ubuntu based Linux as well.
1. Install via PPA
Open Terminal and paste the following commands
wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -sudo wget http://deb.playonlinux.com/playonlinux_precise.list -O /etc/apt/sources.list.d/playonlinux.listsudo apt-get update
sudo apt-get install playonlinux
2. Install using DEB package
